Problem Statement: I've attached a picture of his notes. For a sorted array, to update it he put: O(logn)+O(1) Relevant Equations: O(n) + O(logn) = O(n) I don't see how it can be O(logn)+O(1) and not O(logn)+O(n) in the worst case After you find the index that needs updating, and you...

what does it mean when you say the stars all fall in on each other?And what does the line uniform distribution of stars outside this region mean?and what does this line mean- again fall in?what does fall in mean? would really appreciate some help in understanding the meaning in simpler words...

I study of interaction between a system with a reservoir considering a weak coupling between them. I consider a bosonic bath, the initial state are separable and the operator of interaction between the system and bath is linear in the displacements of the oscillators. . In the book "Quantum...

what I know d=35.75 t=? what am I meant to do with this problem? I'll add more to this area once I know some more. thanks. Is the leafs velocity considered inital? if so I know Vi

What is the difference between time dilation (t is the stationary reference frame) t = Description: If two successive events occur at the same place in an inertial reference frame, the time interval 􏰋t0 between them, measured on a single clock And this equation for time, if we take t' as the...

Suppose I "produce" positron-electron pairs one at a time (by produce I mean in plain language the inverse of annihilation). Next I measure the vector of the magnetic moment of each positron. Is each pair that is produced entangled? Without measuring the electrons, can I now be much more certain...

Hello, I'm trying to solve this, any idea please? Basically: Demonstrate for the next three processes if the Time Series would be stationary, if not, it should establish the conditions for it to be stationary. Thanks

Which of these premises is impossible or incorrect according to our current understanding of quantum entanglement? Given 2 entangled particles, p1 and p2: Observing paired particle p1 induces a change in spin on paired particle p2. There a way of detecting a change in spin on particle p2...

Thanks

Summary: how can a train traveling at light speed, travel at two different speeds being the same train, depending upon whether you are on the train platform or in the train You say good bye to your friend at the train station. You get into train that will travel at just under light speed...

In Smolin peer reviewed papers, he proposed time was fundamental. The ideas were summarized briefly in his new book "Einstein's Unfinished Revolution. He wrote that "If time is more fundamental than space, then during the primordial stage, in which space is dissolved into a network of relations...

Hi there, I have a query about electric power in AC systems. I am Chilean, and over here the power supply is 220 V (rms) at 50 Hz. Some countries use voltages in the range 200-230, but others use 110 V or so, at frequencies of 60 Hz. There is no uniqueness, but all work. My question is...

I am trying to improve the run time for a friend's child's ride on toy. The drive system is currently similar to Plum 550 20000RPM Gearbox with DC Motor,6V Motor with Gear Box with a small 6v battery. I replaced the battery with a 12V 20AH T6 SLA Battery. I'm not sure I'm using the correct...

In wikipedia text Lyaponov time is defined as inverse of the largest Lyapunov exponent. I have some difficulties with the units. Lyaponov exponents are dimensionless? So Lyaponov time is also then dimensionless? Right? How then in wikipedia article we get Lyaponov time in time units? Could you...

I don't entirely get why we usually say that only the shortest path contributes in the path integral. If you calculate the volume of nth fresnel zones which is the locus where the path length is between n-1 and n wavelengths from the shortest path in 3 dimensions, they are the same I believe. So...

Looked at some lottery wins and something was fishy. This a lottery where you pick 5 numbers out of the set (1,2, ..., 50). When no one wins, the money goes to the next iteration of the game so the prize gets bigger and bigger. It seemed that a win was too regular around every 2 or 3 weeks and...

I read that just a few feet difference in height would show a different rate of time and that was measurable. However, If the clock that is at a more elevated position it will be traveling through more space, is that what is responsible for the difference in the rate of time for that clock? I...

Summary: Does the "problem of time in quantum mechanics" go for Lorentz-invariant quantum mechanical theories like QED? Everything I read about "the problem of time in quantum mechanics," i.e. absolute time in QM clashing with relativity's relative time coordinate and relativity of...

I assumed that i had to take 5 time constants which would give the time taken to charge fully i assume then divide by 10 giving me a total number of readings of 34 , the answer is 6 yet they only used a single time constant to determine the number of readings? as this give me an answer of 68 or...

Has/Can gravity wave time distortions be measured to any degree of accuracy as does LISA measures space distortions? If not, why not?

Problem Statement: I have a canister (0.15L Volume). This will be filled with compressed air. A solenoid valve attached has a diameter of 2mm, and the air will flow through this into a pipe which leads to a balloon. The pipe diameter is 3mm, with a length of 300mm. The pressure required to...

I was reading my book on circuit analysis on chapter about RLC response and became curious about how to get an approximate value for the settling time of the response. Particularly this response My first approach was to use the upper envelope of the response and equate to 1 percent of its...

If we reversed the second law of thermodynamics, and entropy decreased, and also managed to reverse the motion for all matter in the universe, so that in 24 hours, everything would return to the state it was at then, would time be said to be flowing backwards? Or would time still be flowing...

The graph provided is below. The problem asks for the speed of the wave at 0.12s. I used the formula v=w*xmax*cos(wt), provided in our textbook where xmax is the amplitude of 2 cm, w (omega) is 2pi divided by the period of 0.2. However, for some reason this formula doesn't give me the correct...

So imagine there are now two dimensions of time, instead of the one dimension which we're used to. The laws of physics which we're used to won't make anymore sense unless they're adapted for the two dimensions of time. How would you adapt them?

I am working with signals that look like the following. The curve has the same form in both frequency and time domain. I am trying to calculate the ratio of two distances: The distance between two adjacent red "x"s (known as the free spectral range (FSR)). The distance between two adjacent...

Hi all, I have experimental nuclear magnetic resonance data that describe T2-relaxation of the nuclei in the sample of interest. The experimental points obey bi-exponential dependence: I = I1*exp(-t/T2_1) + I2*exp(-t/T2_2), where I is current intensity, I1 and I2 are intensities which represent...

Hi, just a question regarding neumann conditions, I seem to have forgotten these things already. I think this question is answerable by a yes or a no. So given the 2D heat equation, If I assign a neumann condition at say, x = 0; Does it still follow that at the derivative of t, the...

The question before asked to find the net force as a function of time which I got: F = 4.83×10¹⁰ (1.65×10⁻⁸ t − 7.41×10⁻⁶) N I just have no idea how to do it with the y directed force since I only have a horizontal acceleration equation. Thanks so much to anyone that helps, I appreciate it!

Helpp meee pleaseee

Summary: I've posted this in a few forums but still confused on this problem. If the plane is moving at 200km/h and the wind pushes the plane with a velocity of 85km/h, then the resultant velocity would be 217km/h, and using sine inverse, 217.sin(theta=85, I got 23°, which is B, but the answer...

Equations: Question: Using the equation for t' I got the answer -0.00000499756s (Wrong anyway) As we know the values: v = 0.67c m/s x = 3900 m t = 0.000005 s Also how can time be negative? Does this mean that event 2 happened before the first event when t = 0?

Hello, I have the force defined as a function of time, where F=A-Bt and A=100N, B=100Ns-1. I have to determine, how long it will take for object to stop, if t0=0s and v0=0,2ms-1 and mass of the object is m=10kg. Can somebody please help me with this, because I'm having hard time with this task.

Tonight I'm taking my wife and parents to Brian Cox's World Tour "ADVENTURES IN SPACE & TIME" with sidekick Robin Ince. All his European stops sold out and so far all of his US stops have been close to selling out. I've been impressed because he's not quite the household name Neil deGrasse Tyson...

Note: Maths has always been kinda a weak point for me in school. Anyway. From hereon I'm going to talk about this in the context of a train for simplicity, even though this is actually needed for an entirely different context - but I don't think this is relevant for the problem. In terms of my...

Hello, I've got this question: A 16 MB file is compressed using a compression ratio of 4. The resulting compressed file is transmitted over a wireless connection that offers a maximum data rate of 1.2 Gbps. If a throughput of 60% can be achieved, and assuming there are no other transmissions...

Hello people, I have a question regarding the time calculation. could you please let me know if there are any equations with which I can find the time to generate steam in the header for certain pressure level. lets say I am supplying fuel and mass flow of water to the boiler at certain...

Hi, I have some crucial questions belong to statistics: First, How can we derive the variance function with respect to mean for a given data? Secondly, I would like to ask: what method should we employ if the variance in time series behaves like a high order (such as ##𝑎𝑢_𝑡^5+𝑏𝑢_𝑡^4+𝑐𝑢_𝑡^3##...

Is it possible that time is just another coordinate axis? That it can be moved freely into backwards and forwards at any speed. And for some reason we as humans can only see it moving forward? and communicate at a definite speed in time. Maybe everything is already calculated and solved, and...

It is obvious that there is a one-to-one relationship between real numbers (defined to include infinity) and their multiplicative inverses (assuming we map the inverse of zero to infinity and vice versa). Thus, one should be able to replace the distance between two points in space with it's...

I just watched a youtube video saying that somewhere in a black hole, time is bidirectional (can go to the future and can go to the passed), but space is one-directional. Any introduction material on this subject? Thanks in advance!

All I've done so far is think about F_net. Since F=ma, and a is a vector, I was thinking that I should find the x and y components of a and then try to calculate F_net that way, but I'm confused as to where I should use x(t) and y(t). Or instead, thinking about it as the change in momentum over...

Since the metric is euclidean in coordinates ##(ict,x)## it can be drawn in a plane, but if the metric is ##diag(1,-1)##, can both axis still be drawn in a plane ?

here I am trying to find ##\frac{d}{dt}dx## where ##x(t)## is the position vector Now ##\frac{d}{dt}(v_x(x,y,z,t)dt)=\frac{dv_x}{dt}dt=\frac{\partial v_x}{\partial t}dt+\frac{\partial v_x}{\partial x}dx+\frac{\partial v_x}{\partial y}dy+\frac{\partial v_x}{\partial z}dz## Now dividing by ##dx##...

I have been reading a book on classical theoretical physics and it claims: -------------- If a Lagrange function depends on a continuous parameter ##\lambda##, then also the generalized momentum ##p_i = \frac{\partial L}{\partial\dot{q}_i}## depends on ##\lambda##, also the velocity...

I came up with this formula. A takes 20 days to have 80% completion. Simple algebra gets that A takes 25 days to complete finish by themselves. Now I'm trying to come up with a formula. ##1/.8(1/25) = 1/20## with 80% completion. Now I'm working with the remaining 20%. ## 1/.2(1/25+1/b)##...

The Singapore Flyer is a very tall Ferris wheel.It is 315 meters tall and has a diameter of 150 meters. Each revolution takes about 30 minutes. If you were allowed to ride for 3 hours, how far would you travel? How much of a mile or how many miles would you travel?

For Initial Value problems I want to implement an ODE solver for implicit Euler method with adaptive time step and use step doubling to estimate error. I have found some reading stuff about adaptive time step and error estimation using step doubling but those are mostly related to RK methods. I...

I accept that time can pass at different rates depending on if the applied motion or gravity (both a parameter in some formula) and as a result time passes at a different rate. However, this seems to imply that we have some control over how slow time may pass. So, if that is just a fact of the...

I would like to ask a question on whether there is a proportionality between volume of a balloon, and the time it takes to deflate. I have conducted several balloon hovercraft experiments. I need to find the relationship between the amount of air pumped into the balloon and how long the...
