Answer:
Yes, the magnet force will cause the motor rotate through a full rotation. So the friend who claims to have built a motor by attaching a shaft to the core of a galvanometer and removing the spring is correct.

Answer:</h3>
24.94 L
<h3>
Explanation:</h3>
<u>We are given;</u>
- Moles of Helium, n= 1 mole
- Pressure of the gas, P = 100 kPa
- Temperature of the gas, T = 300 K
We are required to calculate the volume of the balloon
- We are going to use the ideal gas equation;
- According to the ideal gas equation;
PV = nRT , where R is the ideal gas constant, 8.314 L.kPa/mol.K
V = nRT ÷ P
= ( 1 × 8.314 × 300 K) ÷ 100 kPa
= 24.94 L
Therefore, the volume of the balloon is 24.94 L

Explanation:
Answer:
Explanation:
As we know that loop is placed in YZ plane and magnetic field is along x direction
So here net force on the side of the loop which lies along Y axis is given as
here we know that on Y axis z = 0
so B = 0
so we have
now on the opposite side we have z = a
so magnetic field is given as
so force on that side is given as
so net force on the loop is given as
