Which property of potential energy distinguishes it from kinetic energy?

2 answers:

6 0

There are several differences, however a big property that distinguishes the 2 is that potential energy cannot be transferred, whereas kinetic energy can.
We can see this for example in a bow, when you pull it back it has elastic potential energy because of the strain in the bow, however you can't transfer this potential energy to another object, whereas the flying arrow can transfer it's KE to the target it hits as several things including thermal and sound energy.

Answer:

The speed of the particle after travelling for 0.5 m is 100 m/s.

Explanation:

It is given that,

Mass of the particle, m = 0.01 kg

Net charge on the particle, q = -0.05 C

Electric field strength, E = 2000 V/C

Distance travelled by the particle, d = 0.5 m

The work done due to motion of the particle is balanced by the change in kinetic energy as :

$Fd=\dfrac{1}{2}mv^2$

v is the speed of the particle

F is the electric force

$qEd=\dfrac{1}{2}mv^2$

$v=\sqrt{\dfrac{2qEd}{m}}$

$v=\sqrt{\dfrac{2\times 0.05\times 2000\times 0.5}{0.01}}$

v = 100 m/s

So, the speed of the particle after travelling for 0.5 m is 100 m/s. Hence, this is the required solution.

In what setting do all frequencies of electromagnetic waves travel at the same speed?

Irina-Kira [14]

All electromagnetic waves travel in vacuum (space) at the speed of light (3 * 10^8 m/s). Radio waves is just a member of the electromagnetic spectrum. All electromagnetic waves follow the wave equation: speed = frequency * wavelength. With all electromagnetic waves, the speed in space is the same.
