there are three axes when the angle made between each angle is 90deg. what would be the situation if this became 60deg. i mean how many axes would be there

Hi everybody! Could somebody please assist me with an explanation as to why the following: arg (z+3-2i) = 135degrees : has its centre at -3,2 and that is the place where you begin the argument (ie go 135 degrees) Please note, just beginning complex numbers. Sorry if can't understand question...

can someone give me a hand on this one? How many grams of water at 20 degrees Celsius can be converted into steam at 500 degrees Celsius with 10 kJ of energy? wat i know is that this question is 2 parts: Water being heated to 100 C (80 C change)using the specific heat of water n then...

Are there any benefits to getting a BBA (4-yr program), and then getting a BSc (hopefully followed by med-schoo). So basically, would one accomplish anything by getting business and medical degrees? Just curious

An angle is given to one significant figure as 7 degrees, meaning that's its value is between 6.5 degrees and 7.5 degrees. Find the corresponding range of possible values of the cosine of the angle. Is this a case in which there are more significant figures in the result than in the input data...

I have worked and worked at this problem and it is just not clicking. It is now that I wish geometry would have made sense to me. I am trying to find the resultant vector made by 115 km at 80 degrees and 85 km at 15 degrees. I have been using the graphing method my teacher showed me. I...

Hi, can someone explain me the relation between the degree of a taylor series (TS) and the error. It is for my class of numerical method, and I do not find a response to my question in my textbook. I mean when we have a function Q with two variables x and y,and we use a version of TS to...

I posted this in the homework help section but got no responses so I thought I'd try posting it here. I want the answer to the question, but really I'm looking for the relationship between the values. Q: A star located 135 degrees from the solar apex on the celestial sphere is at rest in...

My guess is that 360 has no mathematical advantage, but it has something to do with 360 (and something) days in a year, or it was derived from some other number of importance. :confused:

A claw hammer is used to pull a nail out of a board. The nail is at an angle of 60 degrees to the board, and a force F1 of magnitude 500 N applied to the nail is required to pull it from the board. The hammer head contacts the board at point A, which is 0.080 m from where the nail enters the...

Why was the number '360' chosen to be the number of degrees in a complete revolution? How far back does the number go?

1)I am very interested to know about studies being done into the uses of atoms at 0 degrees Kelvin (I understand this as the temperature at which atoms cease to oscillate?) Apparently this has possible uses as nano-computers whereby a normal object, such as a coin can house massive memory...

A 1.12 mol sample of an ideal diatomic gas at a pressure of 1.00 atm and temperature of 491 K undergoes a process in which its pressure increases linearly with temperature. The final temperature and pressure are 735 K and 1.39 atm. Assume 5 active degrees of freedom. Neither pressure nor...

Hi guys, Just a quick question. In my lecturers notes, he has mobility and degrees of freedom as different things. With a separate equation for each. However, when I went searching the net for some info because I couldn't understand the notes, I found it to be different. The sites I...

why radians are used in calculus instead of degrees?

the question: a board 2 ft long with weight 50 lb is pressed against a wall. what force, applied at 30 degrees, should be applied to keep it horizontal? i'm not sure how to go about this, so i started by converting the weight of 50 lb to 22.67 kg, then getting a force of mass at 2.31 N then...

Need help... secx=3.45 (0<=x<=2pi) (Accurate to 2 decimal places) secx=-5.2 (0<=x<=2pi) (Accurate to 2 decimal places) How do you do these questions?...i am getting mixed up by doing it on the calculator...use radian or degrees mode??...cos or cos-1?...and also about csc and cot too...can...

From the Comptom Scattering formula, you get (E-E')/E E' = (1/mc^2)(1-cos@). Can someone tell me how you could find E'/E at the min of 180 degrees. I've tried using the conjugate, and other methods, but I can't get E'/E out of it. I must be doing something wrong. Thanks.

A room has temp at +22 degrees C, and after 8 hours it has fallen to 15. What is the rooms "time constant" when the outdoor temp is -5 C? I have no idea what is beeing asked about here, could someone help me...?

hey all could anyone explain the idea of combining degrees ... when can i combine , is it when i finish from a certain major or ?? should both degrees be related to each others , i mean math and something related to it let's say quantum physics or whatever ... does every university provide...

A flash light is pointed at a wall so that the angle between the beam and the wall is 65 degrees a) which conic section is produced? I am not sure if this is asking for the shape but I think the answer is an ellipse b) How would you adjuct the angle of the beam to produce a circle on the...

so my given is 1.52 20degrees = 1.10 sin r im trying to find sin r which comes out to 18.9 degrees but I am not sure how find that, can somebody help me out please? so you do 1.10/1.52 do you divide that into sin 20?

Anyone know enough about TI-83s to help me out? For some reason whenever I try to graph a polar equation on mine it gives me what the graph should look like for radians when degrees is the mode of choice and vice versa. For example, if I were to graph sin(theta) I get a nice pretty circle when...

If an hour hand moves 1/60th of a degree each minute how many degerees will it move in one hour?

1. Calculate the rms speeds at 20 degrees celcius of atoms of helium (4u)? 2. The escapte speed from the surface of the Earth is 11.2 km/s. Find at what temp. the following gas (O2) have this value as the rms speed? 3. One mole of an ideal monatomic gas is heated from 0 degrees celcius...

The theory of quantum fields is very strange, indeed, I must admit. Usually in books they introduce a quantum field from the standpoint of a vibrating string in one dimension. Along the string are discrete points or masses that when one of which are disturbed a disturbance is created along the...

this should be a simple question, but I am just not getting the right answer. I need to change 25 degrees to radians. I know, that 360 degrees = 2pi radians, but I am not getting the right answer. thanks for the help

Consider a situation where a friend have a red laser or a torchlight shining across the room. And you are standing at the side, perpendicular to the light beam. If light traverse in a straight line, why is that you can see the light shining across the room when you know that the light that comes...

Ok, degrees measured in a circle are measured from the center, the inside. A square's, for example, is not measured from the center; if this were the case, all polygons would be 360 degrees. Polygons are measured from the points at which lines intersect, making the degrees given to a circle, and...

I was discussing with my friends that problem: If we have a cone, upside down, rotating with angular speed constant, how much degrees of freedom, the system has? Ok, I think that if the movement is restricted to rotate around a static axis, and the speed of rotation is constant, you don't...

A ray of light strikes an interface between materials 1 and 2 and enters the new material(2). The angle of incidence is 40 degrees. The index in material 2 is 1.5 times that of material 1. The refraction angle is ( in degrees):

Can't quite figure out how to start this problem. If Earth's radius is 6378 km and has a period of 24 hrs. find: a) centripetal acceleration of a particle at the equator. I did this and got 0.03 m/s^2, but I can't figure out how to start the second part. b) the centripetal...

Can anyone help me solve the following question: A particle is moving vertically at 4.8 m/s and accelerating horizontally from rest at 1.7 m/s2. At what time will the particle be traveling at 32 degrees with respect to the horizontal? I have got various answers such as 0.894s, 0.44704s...

Does anyone have any thoughts about how I could measure temperatures up to 1200 degrees F? I could buy a pyrometer or piece one together with a thermocouple and multimeter, but just wondering if there is an easier way to do it. Thanks, Jeremy

When considering the three dimensions of space and our freedom of movement in that space, does our ability to change our state of motion (acceleration) imply an existence of a fourth dimension, ie. four space-time dimensions? Given three dimensions each mutually perpendicular, we can move...

I know this is an easy problem, but I need to know 3 sets of polar coordinates for the Cartesian coordinates (-4,4\sqrt{3}}) So I graphed the points and got the hypotenuse, r = 8. How do I convert 4\sqrt{3}}) to degrees? (4\sqrt{3}}) = 6.92820 Is this in radians...

If you were to introduce diphosphate and oxygen to one another at apporx 40 degrees celcius, would they combust instantaneously?

I find it interesting how the Earth tilts only a few degrees and the weather changes so dramatically. Question: How far fetched would it be to think that the Earths weather system remains a stationary shell and the Earth simply rotates underneath it. To put it another way, the weather "shell"...

[SOLVED] Grads Vs Degrees Knew a civil engineer whose soecialty was hydroelectric dams. He used 400 grads exclusively - as opposed to 360 degrees. Would like to know the rationale behind this...please!

This hypothesis basically states that any 2 people on Earth are connected by no more than six levels of acquaintances.
