Answer:
The correct option is;
A. The potential energy between both like charges and like poles increases as they move closer together
Explanation:
Here we have that when we move the like poles of two bar magnets close to each other, there is an increased resistance in the continuing motion, therefore for each extra gap closer achieved, there is an increase in potential energy
Similarly, when two like charges are brought closer together, the potential energy, or the energy available to push the two like charges apart increases charge as the as the charges are brought closer together
Therefore, the correct option is the potential energy between both like charges and like poles increases as they move closer together.
D is the point where the planet moves the fastest. This is because it is in the perihelion, where the planet is moving at it’s fastest pace
In Linear motion the swimmer swims
//
I'm not really sure but I do know that it's not 0 because the object is still moving, even if it's only moving at 1 m/s.
The velocity of the wave is 40 m/s
Explanation:
The relationship between the velocity of a wave and its frequency and wavelength is given by
where
v is the velocity
f is the frequency
is the wavelength
For the ocean wave in this problem, we have:
(wavelength)
f = 4.0 Hz (frequency)
Therefore, its velocity is
