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.
Answer:
-90.8 Joules
Explanation:
A = Area of container = 50 cm²
d = Length pushed = 15 cm
P = External Pressure = 121 kPa
Change in volume
Work done
Work done by the system is -90.8 Joules
Answer:
