Answer:
<u><em>20 m/s.</em></u>
Explanation:
Mass of body m: 10kg
The kinetic energy of the body is given as; 
Value of Kinetic energy K.E = 2000 Joules
V is the body's velocity, and M is the body's mass.
Calculating the value of velocity;
= 
Velocity maintained by the body having a kinetic energy of 2000J is
20 m/s.
Force and distance is the main criteria for the movement of the object. The work of the object can be defined as the ‘product’ of the force and distance.
By the work-energy theorem, the total work done on the car is equal to the change in its kinetic energy:
<em>W</em> = ∆<em>K</em>
<em>W</em> = 1/2 (0.34 kg) (22.9 m/s)² - 1/2 (0.34 kg) (6.5 m/s)²
<em>W</em> ≈ 82 J
Gamma waves have a short wavelength. The closer the wavelength (
) the higher frequency the wave is
