Explanation:
t = Time taken
u = Initial velocity = 32 m/s
v = Final velocity = 0
s = Displacement = 60 m
a = Acceleration
m = Mass of car = 1400 kg
Work done is given by

Answer:
Explanation:
The capacitance of a capacitor in terms of the dielectric constant, area of the plate and the distance separating the plate is given by:
Where A = Area of the plate
d = distance between the plates
dielectric constant
Case 1:
When a meta slab of thickness, a, is added between the plates of the parallel plate capacitor , the effective separation between the plates becomes d+a
Therefore the capacitance of the capacitor becomes:
.......................(1)
Case 2:
Introducing a dielectric with dielectric constant K between the plates, the capacitance of the capacitor becomes:
.........................(2)
Equating (1) and (2)
Answer:
The minimum magnetic field is 0.078 T.
Explanation:
Given that,
Current = 16 A
Side = 15 cm
Mass
Mass each segment in given square loop is
We need to calculate the torque due to gravity
Using formula of torque
The torque due to magnetic field
The equilibrium condition
Put the value into the formula
Put the value into the formula
Hence, The minimum magnetic field is 0.078 T.
