A student presses her palm by her thumb with a force of 75 N . What would be the pressure under her thumb having contact area is 1.5 cm2

Pressure = 50 N/cm²

Explanation:

Given:

Force = 75 N

Area = 1.5 cm²

Find:

Pressure

Computation:

Pressure = Force / Area

Pressure = 75 / 1.5

Pressure = 50 N/cm²

c, 1a hope this

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
