Awesome, completely makes sense. So the reduced pressure of the hole causes the water to flow towards it and ultimately 'spray' upwards. (I assume it would reach a max height of 20cm to once again obey Bernoulli's equation)
Really appreciate the help.
Ah that makes a bit more sense.
Maybe I'm struggling conceptually then.
So is the pressure at -20cm equal to 1960Pa everywhere except for directly underneath the area of the hole where it's equal to 0?
The problem statement:
You and a friend are in a boat in a river, the combined mass of this system is 200kg.
The boat hits a rock and a hole of 1-cm diameter forms in the bottom of the boat, which is 20cm below the water line.
1) What is the gauge pressure of the water at the depth of the...
This is falling quickly off the front page so I'm going to be petulent and bump it.
Didn't post any formulas because alfredo/reflectivity and emissivity are pretty much just ratios.
Compound A has an albedo value (visible spectrum) of 0.08, and an emissivity (infrared) of 0.08.
Compound B has an albedo value of 0.04 and an emissivity of 0.88, in the same spectrums.
We need to explain why A is more effective at transferring energy to the water flowing behind it, when...
Proper length is measured distance in the FOR where the objects are at rest, i.e. in frame S'.
I'm using the equations L' = L/gamma and x' = gamma(x-vt) and trying to solve these simultaneously, am I on the right track?
I can't determine whether L' = x' and L = x, or L' = x and L = x', though...
OK, so I defined a stationary reference frame as S, and defined the frame in the question as S'. S' is moving wrt S at a velocity v.
So the proper time is the Δt observed in S', and the proper length is the Δx observed in S'.
I think I've worked out a, but struggling with b. I'm using the...
Suppose that two events occur on the x-axis of an inertial frame, Δx apart with a time interval between the events of Δt.
a) the proper time interval between the events is...?
b) the proper distance between the events is...?
I think I'm just getting confused by the wording. I imagined that...
"This figure is a snapshot graph of the instantaneous velocity of the particles on a string. The wave is moving to the left at 50 cm/s.
Draw a snapshot graph of the string's displacement at this instant of time."
So it seems to be a quite basic question, where it's pretty much just an...
That's the problem, I don't know which equations I need. Do I need time dilation? Do I need to consider length contraction? Do I need to use a Lorentz transformation on the coordinates of something? Do I need to get a Lorentz transformation of a velocity?
I am completely lost with this...
The question...
Two events are observed in a frame of reference S to occur at the same space point, with the second event occurring after a time of 1.70s. In a second frame S' moving relative to S, the second event is observed to occur after a time of 2.25 s.
What is the difference Δx...
I do have a specific example/problem, but my actual question is more so conceptual (I'm sure that seeing someone confused by relativity is a first around here!).
The problem:
Two rockets are each 1000m long in their rest frame. Rocket Orion, traveling at 0.900c relative to the earth, is...
