The period t of a simple pendulum is expressed by: √

where ‘l’ is
the length of the pendulum and ‘g’ is the acceleration due to gravity. show
that the formula is dimensionally consistent

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?

What is the scientific definition of energy that relates to work
