Answer:
Kinetic energy
Explanation:
Kinetic energy because its energy of motion and when we usually clap our hands it makes noise
Answer:
c- heat for electricity generation process comes from nuclear fission
Explanation:
nuclear fission is splitting of atoms to release energy held at nucleus of atoms
Terminal velocity is the velocity at which a falling body experience
when its weight is equal to the force resistance of force opposing the
fall.
At terminal velocity the acceleration of the body is zero,
which implies that the value of the this velocity is a uniform.
<span>The work done is 3.0 Nm.
We can us the equation Work = Force * Distance, where Force = 75.0 N, and distance is xf – xi = 3.00 cm - -1.00 cm = 4.00 cm. Convert centimeters to meters by moving the decimal place to the left by two places to get 0.04 m. Plug these values into the Work equation:
Work = Force * Distance
Work = 75.0 N * 0.04 m
Work = 3.0 Nm</span>
