(a) if a proton with a kinetic energy of 6.2 mev is traveling in a particle accelerator in a circular orbit with a radius of 0.500 m , what fraction of its energy does it radiate per second?

The fraction of its energy that it radiates every second is .

Explanation:

Suppose Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating charge that has charge q and acceleration a is given by

Given that,

Kinetic energy = 6.2 MeV

Radius = 0.500 m

We need to calculate the acceleration

Using formula of acceleration

Put the value into the formula

Put the value into the formula

We need to calculate the rate at which it emits energy because of its acceleration is

Put the value into the formula

The energy in ev/s

We need to calculate the fraction of its energy that it radiates every second

Hence, The fraction of its energy that it radiates every second is .

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains
