Answer:
The voltage induced in the coil is 1.25 V.
Explanation:
Given;
number of turns, N = 100 turns
cross sectional area of the copper coil, A = 0.1 m²
initial magnetic field, B₁ = 0.5 T
final magnetic field, B₂ = 1.00 T
duration of change in magnetic field, dt = 4 s
The induced emf in the coil is calculated as;
Therefore, the voltage induced in the coil is 1.25 V.
Temperature is absolute while heat is relative. The direction of heat always travels from the warmer object to the cooler! Hope this helps!
Answer:
22cm
Explanation:
focal length = 11cm
radius of curvature,r = 2f
r= 2 x 11
r=22cm
Answer:
Explanation:
Given
Train travels towards south with a velocity if 
Rain makes an angle of 
with vertical
If an observer sees the drop fall perfectly vertical i.e. horizontal component of rain velocity is equal to train velocity
suppose 
is the velocity of rain with respect to ground then
Therefore velocity of rain drops is 27.36 m/s
