The time period t of a simple pendulum is given by the relation
t=2pi sq rt l/g
, where l is the length of the pendulum and g is the gravitational field at the place. from the above relation, we can say that:

t ∝ g

t ∝ l

t2 ∝ g

t2 ∝ l

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
