When five people whose average mass is 80 kg sit down in a car, they find that the car drops 0.91 cm lower on its springs. then they get out of the car and bounce it up and down. the acceleration of gravity is 9.8 m/s 2 . what is the frequency of the car’s vibration if its mass (empty) is 3000 kg

1.91 Hz

Explanation:

Given

mass of each person

car lowers by

mass of car

Weight of 5 person Pushes car by 0.91 cm

therefore

where

and angular frequency of car is given

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
