On a .75-meter table sits a book whose mass is .5 kilograms. How much Potential energy does it have?

P.E = 3.675  J

Explanation:

Given data:

Height of table = 0.75 m

Mass of book = 0.5 kg

Potential energy = ?

Solution:

Formula:

P.E = mgh

g =acceleration due to gravity =  9.8 m/s²

by putting values,

P.E = 0.5 kg× 9.8 m/s² ×0.75 m

P.E  = 3.675 kgm²/s²

J = kgm²/s²

P.E = 3.675  J

Explanation:

Gravitational potential energy can be found using the following formula.

Where m is the mass, g is the gravitational acceleration, and h is the height.

The mass of the book is 0.5 kilograms. The acceleration due to gravity on Earth is 9.8 m/s². The height of the book is 0.75 meters.

Substitute the values into the formula.

Multiply.

The book has 3.675 Joules of gravitational potential energy.

b. examine and describe cells

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
