(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 .

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
