A simple pendulum is used to determine the acceleration due to gravity at the surface of a planet The pendulum has a length of 2 m and its period is measured to be 2 s. The value of g obtained in this investigation is most nearly :A. 1 m/s2 B. 2 m/s2C. 5 m/s2 D. 10 m/s2 E. 20 m/s2

E. 20 m/s^2

Explanation:

The period of a pendulum is given by the following equation:

Where T = time period (in seconds)

L = length of pendulum

and g = acceleration due to gravity

Substituting the values from the question we get:

Solving for g, we get:

g = 19.74 m/s^2

Closest option to this is option (E).

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
