What are the two factors that affect the period of a pendulum? a. tension on string and acceleration due to gravity b. length of string and acceleration due to gravity c. acceleration due to gravity and friction d. tension on string and mass of bob e. length of string and mass of bob

B.  length of string and acceleration due to gravity

Explanation:

The period of a simple pendulum is given by:

where

L is the length of the pendulum

g is the acceleration due to gravity

From the equation, we clearly see that the period of the pendulum depends only on two factors: the length of the pendulum and the acceleration due to gravity.

where's the following? you gotta add it to know what the choices are

explanation:

c) up is the direction the magnetic force is acting on the charge.
