Answer:
The speed of the rod is 2.169 m/s.
Explanation:
Given that,
Mass = 0.100 kg
Current = 15.0 A
Distance = 2 m
Length = 0.550 m
Kinetic friction = 0.120
(a). We need to calculate the magnetic field
Using relation of frictional force and magnetic force
Where, l = length
i = current
m = mass
Put the value into the formula
(b). If the friction between the rod and rail is reduced zero.
So,
We need to calculate the acceleration
Using formula of force
Put the value into the formula
We need to calculate the speed of the rod
Using equation of motion
Put the value into the formula
Hence, The speed of the rod is 2.169 m/s.
Answer:
Explanation:
When water droplet condenses on the outer wall of glass of ice , it releases heat equal to mass x latent heat of condensation of water . This heat reaches the ice melting inside glass . Due to this heat , the melting process is accelerated .
Hence the process of melting gets accelerated when water droplet condenses on the outer wall of glass containing mixture of ice and water .
