1)
What is the effect of resonance in a set of coupled pendulums?
The maximum amplitude of oscillation in all pendulums
The frequency at which the pendulums come to a complete stop
The synchronization of motion between the pendulums
The maximum amplitude of oscillation in pendulum. The length of that pendulum and oscillated pendulum is same
2)
In a set of coupled pendulums, resonance occurs when:
A. The lengths of the pendulums are equal.
B. The masses of the pendulums are equal.
C. The natural frequencies of the pendulums match.
D. The amplitudes of the pendulums are at maximum.
B and C
C and D
A and C
A and B
3)
What happens to the amplitude of oscillation in a set of coupled pendulums at resonance?
It increases
It becomes zero
It decreases
It remains constant
4)
What determines the natural frequency pendulum?
Damping coefficient
All of these
Length of the pendulums
Mass of the pendulums
5)
Which of the following statements are correct?
Statement 1: In set of coupled pendulums, maximum transfer of energy happens to pendulum of same length.
Statement 2: In set of coupled pendulums, transfer of energy is same to all pendulums.
Both are incorrect
Both are correct
Statement 1 is correct
Statement 2 is correct
6)
Which condition is required to achieve resonance in a set of coupled pendulums?
The masses of the pendulums are equal
The natural frequencies of the pendulums match
None of these
The amplitudes of the pendulums are at maximum
7)
The time taken for one complete back-and-forth swing of a pendulum is called the:
Amplitude
Period
Damping
Frequency
8)
What happens if the driving frequency of a system of coupled pendulums is significantly different from the natural frequency?
The amplitudes of the pendulums increase.
Resonance occurs.
The pendulums stop oscillating.
The pendulums oscillate with small amplitude than pendulum which is in resonance.
9)
Which of the following statements are correct:
Statement 1: In set of coupled pendulums, all pendulums oscillate in same frequency of oscillated pendulum.
Statement 2: In set of coupled pendulums, pendulum of same length oscillates in same frequency of oscillated pendulum.
Statement 1 is correct
Statement 2 is correct
Both are incorrect
Both are correct
10)
What happens to the period of a pendulum if the length is doubled?
It becomes square root of two times as long
It becomes four times longer
It remains the same
It becomes half as long
