As we know that, f=ma where
f= net force
m=mass of body
a=acceleration
Substitute m and a in the formula and you will get the answer
Answer: 4 A
Explanation:
Given
Voltage 
Power 
Power is given by 
Insert the values

The rating of fuse is slightly higher than the normal operating conditions. Therefore, a 4 A fuse should be used here.

Below is the solution:
9.43 m/s
<span>F = -kx </span>
<span>k = 400 N/m </span>
<span>PE= 0.5kx^2 = 0.5mv^2 </span>
<span>solve, v=9.43 m/s</span>
Answer : Option B) Radiative zone
Explanation : The sun consists of many zones in it. Particularly in the radiative zone, the energy is primarily transported toward the exterior side by the process of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons and energy is transformed from atom to atom.
