Will a pendulum gain or lose time when taken in a deep mine?
The pendulum will take more time to complete one vibration, i.e., it will lose time.
When a pendulum clock is taken inside a mine?
The time period. Either sides of surface of earth g goes on decreasing, hence period increases.
How is the time period of the pendulum affected when pendulum is taken to hills or in mines?
Time period of simple pendulum is directly proportional to the square root of its length. 28. The time period increases as the value of g is less on hills or in mines than that at surface.
Why do pendulum clock loses time?
This means that when the temperature is increased, the time period of oscillation of the pendulum increases. If the time period increases, then the pendulum will complete less than the required oscillation for a given time interval. Hence, we say that at higher temperature, the pendulum loses time.
Why does a pendulum clock gain time when taken from equator to the pole?
we know, acceleration due to gravity, g value at pole is greater than at equator. if it is taken to the poles g value increases. time period decreases so, the pendulum clock gains time. hence, if a pendulum clock gives correct time at the equator then, it gains time if it is taken to the poles.
What will happen to the time period of a simple pendulum if it is taken deep inside a mine and why?
looses time, length to be decreased.
What are the factors on which time period of oscillation of simple pendulum does depends?
Answer: The time period of a simple pendulum depends upon the length of the pendulum, acceleration due to gravity and the temperature. it is directly proportional to the square root of length of pendulum (l) and inversely proportional to the square root of acceleration due to gravity (g).
What would happen to the time period of a simple pendulum when mass of the bob is doubled?
Doubling the mass of the bob will half the period.
What is the displacement of a particle in simple harmonic motion in one time period?
The displacement of particle executing S,H.M. is given by y=5 sin 20πt.
In what conditions is the period of a simple pendulum doubled?
∴ By increasing the length of a simple pendulum by four times the time period will be doubled.
What effect occurs on the frequency of a pendulum if it is taken from the earth’s surface to deep into a mine?
With depth, the gravitational acceleration decreases. As the frequency of pendulum is proportional to square root of g, so with decrease in g, frequency f would decrease.
When a girl sitting on an oscillating swing stands up then the period of oscillation will?
When a girl stands upono a swing, the position of centre of mass of girl is raised. Due to which the effective length of pendulum decreases, hence the time period of swing decreases because T∝√l.
Why does a pendulum clock lose or gain time in summer and winter?
The length of the pendulum used in clocks increases in summer and hence T increases whereas in winter, the length of the pendulum decreases, so T decrease. T increases means clock goes slow.
Why does a pendulum clock loss or gain time in summer and winter?
In the summer the pendulum gets longer by heat expansion and therefore slows down the clock. In the winter the pendulum contracts and speeds up the clock.
Why does a pendulum lose time in summer and gain time in winter?
In winter, due to contraction, the effective length of the pendulum gets shortened, and so the time period is decreased and the pendulum completes more oscillations in a given time i.e. the clock goes fast.
