The answer is partially inelastic collision
In this type of collision there is no conservation of kinetic energy, and the objects don't stick together after the impact.
There is deformation of the ball (which causes heating)
There is friction between the ball and the bat.
And there is loss of energy due to sound.
Answer:
Yes. the wave is a stationary wave
Amplitude=7.91 cm
Explanation:
We are given that an equation
We have to find that the given wave is a stationary wave or not and find its amplitude at x=2.0 cm
We know that equation of stationary wave
Where
Amplitude=
The given equation is of the form of stationary wave equation.
By comparing we get
Substitute the value of x
Therefore, the amplitude of the wave
Amplitude=
Answers:
a)The balloon is 68 m away of the radar station
b) The direction of the balloon is towards the radar station
Explanation:
We can solve this problem with the Doppler shift equation:
(1)
Where:
is the actual frequency of the sound wave
is the "observed" frequency
is the velocity of sound
is the velocity of the observer, which is stationary
is the velocity of the source, which is the balloon
Isolating :
(2)
(3)
(4) This is the velocity of the balloon, note the negative sign indicates the direction of motion of the balloon: It is moving towards the radar station.
Now that we have the velocity of the balloon (hence its speed, the positive value) and the time () given as data, we can find the distance:
(5)
(6)
Finally:
(8) This is the distance of the balloon from the radar station
Answer:
Explanation:
The change in potential is then defined as the negative of the work done by that force. ... You can't have work done by gravity AND a change in gravitational potential energy. You have to do it one way or the other. This means that the most important step in solving work-energy problems is choosing a system.
the phenomenon is An object that has potential energy can transfer that energy into kinetic energy when the object begins to move, due to its mass or position. For example, a person jumping on a trampoline has potential energy when they reach the peak of a jump, and their force changes direction from upward to downward.
