Answer:
The book gravitational potential energy is 0.0784 Joules.
Explanation:
Given:
Mass of book, m = 20 g = 20 ÷ 1000 = 0.02 kg
Table height, h = 40 cm =40 ÷ 100 = 0.4 m
To Find:
Gravitational Potential Energy = ?
Solution:
Gravitational Potential Energy :
Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
Formula is given by
Where,
m = mass
g = acceleration due to gravity = 9.8 m/s²
h = height
Substituting the values we get
The book gravitational potential energy is 0.0784 Joules.
Answer:
A new product is formed
Explanation:
Physical reactions generally result in a change of state (solid, liquid, gas). Chemical reactions generally result in the production of a new product/ substance (structure/ properties are different than the intial reactants'... example= burning wood)
Answer:
The striped magnetic pattern develops because, as the oceanic crust pulls apart, magma rises to the surface at mid-ocean ridges and spills out to create new bands of the ocean floor.
Explanation:
A sound wave is the answer
Answer:
Examples of non-inertial reference frames
One clearcut example of an inertial reference frame is an isolated spaceship, far, far away from the Earth, the Sun, the Milky Way Galaxy, and all other massive objects. Fred places a blue ball into a claw at the left end of the ship, and red ball into a claw at the right end of the ship.
Explanation:
Let us say that you are in a car at a stop light. The car is standing still. The light turns green, and the car accelerates forward. While undergoing this acceleration, the car is a non-inertial frame of reference.
