Question

A slow running pendulum clock can be speeded up by

Answer 1

It can be speeded up by decreasing the length of pendulum because by decreasing length time period of pendulum is decreased and hence speed of clock increases.

Answer 2

A slow running pendulum clock can be speeded up by spherical lenses that is convex and concave lenses.

• Speed is the rate of movement or how fast it reaches, and it is the speediness of the object to reach the place.
• Speed is a scalar quantity and has no magnitude; it is the rate of fastness of the object to reach its destination.
• It is the dimension of the space, and its standard unit is a meter per second.
• Four types of speed are also present.
• The lenses are used for the divergent of the light rays, which helps to transmit the light rays.
• A concave lens has a curved surface.
• It is divergent from straight light rays.
• This lens is used for myopia.
• The concave lens was used in telescopes and peepholes.
• It is used widely, and it is beneficial to all kinds of uses.

Therefore, a slow running pendulum clock can be speeded up by spherical lenses that is convex and concave lenses.
