Question

A rectangular object measures 5cm by 25 cm, has a weight of 25kg. calculate the pressure exerted

Answer 1

Answer:

Explanation:

The weight of an object is the force of gravity exerted on that object. The mass of an object is the amount of matter it has, and it stays the same wherever you are, regardless of gravity.[1] That's why an object that has 20 kilograms of mass on earth also has 20 kilograms of mass while on the moon, even though it would only weigh 1/6 as much. It weighs 1/6 as much on the moon because the force of gravity on the moon is 1/6 of what it is on Earth. Read on for information about and tips on calculating weight from mass.

Answer 2

The pressure exerted by the rectangular block would be 19600 Pa.

1) The pressure exerted by a body is the force exerted per unit area.

2) Mass of object is 25 kg, Hence force exerted would be M*g = 25*9.8 = 245 N.

3) The area covered by object would be 5cm*25cm = 0.0125 m².

4) Hence, the pressure exerted would be 245/0.0125 Pa = 19600 Pa
