Mastery Practices

🟩Easy

Check the homogeneity of the formula for the period T of a pendulum: T=2Ο€βˆš(L/g) where L is the length and g is acceleration due to gravity.

Answer Explanation

🟨Medium

A hailstone of mass m falls through the air and experiences a net force F given by

F=CvΒ² – mg

where v is its speed, g is the acceleration due to gravity and C is the drag factor. Find the base units of C.
