A square tile having 50cm side is made to withstand a pressure of 200N/m^2 find out if a force of 45N can be applied on the tile

Explanation:

Given that,

Side of a square tile, a = 50 cm = 0.5 m

Pressure withstand by it, P = 200 Pa

We know that,

Pressure = force/area

It is the force that tile withstand is 50 N. The force applied upon the time is 45 N. As 45 N can be applied on the tile  because 45 N < 50 N.

the total distance traveled by the car is

30km + 49km = 79 km .
