Here stress is parallel to the surface of the body. So it's a Shear stress.
The power delivered to the coil is 0.5 Watts
<h3>Resistivity of a material</h3>
The formula for calculating the power delivered to it is expressed according to the equation
Power = I²R
where
I is the current
R is the resistance
Given
Current = 0.500A
Determine the resistance using the resistivity formula
R = ρL/A
Substitute the given parameters
R = 10^-6*(25)/0.002²
R = 2ohms
Substitute
Power = I²R
Power = (0.5)²(2)
Power = 0.5watts
Hence the power delivered to the coil is 0.5 Watts

Answer:
body will stop moving if the gravity will be equal to the tension produced in the string so both the forces will cancel the influence of each other leading to the state when the body is in equilibrium
Explanation:
Primary cell
1. They are non-rechargeable.
2. The energy density of primary cells is more.
3. The internal resistance of primary cells is more.
4. Example : Zinc-Carbon cell.
Secondary cells
1. They are rechargeable cells.
2. The energy density of secondary cells is less.
3. The internal resistance of secondary cells is less.
4. Example : Car batteries
Current :
The flow of electric charge per unit time is called electric current. It can be given by the formula as follows :
The SI unit of electric current is Ampere.
1 Ampere is defined as the current that flows with the electric charge of one Coulomb per second (C/s).
