Why is relative velocity AFTER equal to Vf2 minus Vf1 but relative velocity BEFORE equal to V1 minus V2 in the coefficient of restitution formula?
relative velocity is defined as the time rate of change of one object with respect to another object.the relative velocity depends upon the observer i.e.if the velocities of two objects are same then the relative velocity also seems to be equal.
In direct current charges carries have a drift velocity but in alternating current there is no net velocity of the charge carriers. Explain why?
In direct current the charge carries always flow in the same direction, while in alternating current they change direction repeatedly, meaning overall there is no net direction.
What is group velocity in waveguide?
Group velocity in a waveguide is speed at which EM energy travels in the guide.It will always be less then speed light.
The emmiter current of an n-p-n transistor is equal to?
The sum of (base current) plus (collector current).
What is the formula for Kirchoff's current for parallel circuits?
Kirchoffs's current law states that the sum of all the currents flowing out of any point is equal to zero. In other words, the current flowing in is equal to the current flowing out.In the case of a parallel circuit, this means that if a single current branches into two or more parallel branches, then the sum of the currents in the parallel branches must be equal to the original current before it branched.
What is the relationship between current, charge, and velocity in an electrical system where the current is equal to the charge multiplied by the velocity?
In an electrical system where current is equal to the charge multiplied by the velocity, the relationship is that the current flowing through the system is directly proportional to both the amount of charge and the velocity at which the charge is moving. This means that as either the charge or the velocity increases, the current flowing through the system will also increase.
What would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?
As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................
Is it possible for something to have an escape velocity equal to light?
No light is the fastest possible. Nothing escapes the velocity of light. ==================================== Sure. The escape velocity at some appropriate distance from a black hole is equal to 'c'. That's why the hole is black. The exact value of the distance depends on the hole's mass.
Why anything cannot cross the velocity of light?
Because every matter has a mass which tries to stop the matter from gaining the equal or higher velocity as light.
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
The velocity of light is 3.00 which is equal to what?
This question does not make sense. Part (1) "The velocity of light is 3.00" is a statement within the question following Part (2) "which is equal" is again a statement. Part (3) "to what?" is the question. So if I ask, "The velocity to what?" and replace the word "velocity" with "light" to define it better, I get, "The light to what?" and substitute the value of light with the given in Part (1) and add the second statement given in Part (2), I get, "3.00 is equal to what?" Hello? is what I want to ask. Perhaps reversing the original question will enlighten: "What is equal to the velocity of light...which is 3.00?" Wa-la. This was a trick question. The answer in not only within the question itself, but also happens to correlate to the number of minutes wasted answering this...this...
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
The velocity of the body is constant if it covers equal displacements in equal intervals of time. This is because velocity is defined as the rate of change of displacement with respect to time. If the body is covering equal distances at equal intervals, then the velocity remains constant.
When is the instantaneous velocity equal to avg velocity?
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
When do you say that the velocity of the car is equal?
when a car travels equal distance in equal intervals of time its velocity is uniform and equal
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
What is the velocity of light in meters?
the velocity of light is 300000000 m/s
