Answer from: BeautyxQueen

947. 875GeV

Explanation:

According to einstein's E = mC^2

Energy can be converted to mass and mass can be converted to energy. The 'c' in the formula is the speed of light.

When two atomic particle of opposite charges collide they anhilate each other completely to release energy.

The energy released is the sum of the energy they possessed and the energy due to their mass being converted into energy.

Since each particle has an energy of 473 GeV each, then the total sum of the energy they posses is 473*2= 946 GeV

According to experiment, a proton and an anti proton have the same mass, and this has been shown to be equal 1.007276u.

Basic conversion has it that;

1u = one-twelfth the mass of one atom of the carbon-12 isotope.

This means;

1u = 1.66*10^-27 kg = 391 Mev = 0.391GeV,

According to energy mass conversion.

Total mass of the colliding particles = 1.007276 * 2 = 2.014552u

Therefore energy of colliding particles due to mass conversion

= 2.014552 * 0.931GeV

= 1.875 GeV

Total energy liberated in this process equal

946 + 1.875 = 947.875 GeV

Answer from: Quest

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
