Answer:
A. 29.4 Joules
Explanation:
Given parameters:
Mass of the book = 1.5kg
Height of lift = 2m
Unknown:
Potential energy acquired = ?
Solution:
Potential energy is the energy due to the position of a body.
Mathematically;
Potential energy = mgh
m is the mass of the body
g is the acceleration due to gravity = 9.8m/s²
h is the height
Potential energy = 1.5 x 9.8 x 2
Potential energy = 29.4J
The answers is B.) Large number of Africans we’re forcibly taken to American during the slave trade .
The ocean, atmosphere, cryosphere, and biosphere interact with the geosphere via the earth's crust.
Atmospheres are layers of gas that surround planets and other celestial bodies. Earth's atmosphere is composed of approximately 78% nitrogen, 21% oxygen, and 1% other gases. 1: the total mass of air surrounding the earth. 2: Gas surrounding celestial bodies (planets, etc.) The atmosphere of Mars is mainly composed of carbon dioxide. 3: air of a place. 4: Ambient influence or set of conditions An atmosphere of excitement.
The atmosphere is defined as the region of air and gas surrounding an object in space, such as a star or planet, or the air around any location. An example of the atmosphere is the ozone and other layers that make up the Earth's sky as we see it. An example of an atmosphere is the air and gases contained in a greenhouse.
