The pendulum used in a clock is:

• Simple Pendulum
• Compound Pendulum
• Second Pendulum
• None of these

The time taken to complete one oscillation is called

• Frequency
• Amplitude
• Time period
• Acceleration

The number of oscillations made in 1 second is called

• Amplitude
• Time period
• Frequency
• Momentum

The unit of time period is

• Hertz
• Nanometre
• Second
• Centimetre

The relation between time period and frequency is

• f = T
• f = 1/T
• f = square root of T
• f = cube root of T

The maximum displacement of bob from its mean position on either side is called:

• Period of oscillation
• Frequency of oscillation
• Amplitude
• Oscillation

The effective length of a pendulum is related with time period as:

• T is proportional to l
• Square of T is proportional to l
• Cube of T is proportional to l
• T is proportional to cube of L

A simple pendulum is made by suspending a bob of mass 1 kg by a string of length l. Now if the length of the pendulum is increased to 4k, then its time period T will:

• remain the same
• become twice
• become four times
• become half

The time period of a seconds' pendulum clock is:

• 1 s
• 2 s
• 1 min
• 12 h

Time period of a simple pendulum is given by:

• T = 2 x Pi x square root of (g/l)
• T = 2 x Pi x square root of (l/g)
• T = 4 x Pi x square root of (l/g)
• T = 4 x Pi x square root of (g/l)
