30.0g
24.0g
10.0g
6.0g
0.4g
Correct answer is C
Q = charge
i = current
t = time in sec
Mass(M1)
3hours to sec
60*60*3= 10800
Mass(M2)
10hours to sec
60*60*10 = 36,000
36,000 * 3.0A = 108,000
if it takes 10800 current to discharge 1g
how much will it take 108000
10800---->1
108000---x
= 108000/10800
=10
Which process will increase the rate of oscillation of a pendulum?
decreasing the amplitude of oscillation of the pendulum
decreasing the length of the pendulum
decreasing the mass of the pendulum
increasing the length of the pendulum
increasing the mass of the pendulum.
Correct answer is B

Lenz’s law of electromagnetic induction states that
e.m.f. is induced in a circuit whenever there is a change in the magnetic flux linked with the circuit
the induced e.m.f. in a circuit is proportional to the rate of change f the number of lines of force linking the circuit
the induced current in a conductor is in such a direction as to oppose the change producing it
a force is exerted in a current-carrying conductor in a magnetic field.
the induced e.m.f. is proportional to the current producing the magnetic flux.
