Explanation:
because conduction takes place in objects whose particles are close/touching each other therefore conduction happens in solid as liquid and gas paricles are not close to each other
Answer:
An electric motor converts electrical energy into mechanical energy. The process is as follows:
D. When current flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.
Moment of inertia of N₂ molecule about an axis passing through the center of mass perpendicular to the line joining the two atoms=i=2.51 x 10⁻⁴⁷ kg m²
Explanation:
Moment of inertia= i= mr₁²+ mr₂²
m= mass of nitrogen atom=2.32 x 10⁻¹¹pg=2.32 x 10⁻²⁶ Kg
r1= r2=0.0465/2= 0.02325 nm=2.325 x 10⁻¹¹ m
so i= 2.32 x 10⁻²⁶ (2.325 x 10⁻¹¹)²+2.32 x 10⁻²⁶ (2.325 x 10⁻¹¹)²
i=2.51 x 10⁻⁴⁷ kg m²
