The answer is Gravity
There's always a gravity between any 2 objects in this universe. between you and your computer, between you and the floor, between your chair and your table, etc.
We just dont feel it because we live in earth which negates all of those gravities with its own.
Answer:
g = 4.7 × 
m/
Explanation:
Given that the mass of the satellite = 700 kg, and 10,000 m above the earth;s surface.
From Newton's second law,
F = mg ............... 1
From Newton's gravitation law,
F = 
.................. 2
Where: F is the force, G is the gravitational constant, M is the mass of the first body, m is the mass of the second body, g is the gravitational force and r is the distance between the centers of the two bodies.
Equate 1 and 2 to have,
mg =
⇒ g = 
But; G = 6.67 × 
N 
, M = 700 Kg, r = 10000 m
Thus,
g = 
= 
= 4.669 × m/
The force of gravity on the satellite is 4.7 × m/.
Answer:
1. In a coal-fired power plant, chemical energy is first converted to thermal energy. TRUE.
The chemical energy in the coal is converted to thermal energy when the coal is burnt to produce steam.
2. In a coal-fired power plant, approximately 2/5 of original energy in the coal is lost to heat. FALSE.
Approximately 3/5 of the original energy is lost not 2/5 so this statement is false.
3. The molecules in cold air move faster than in hot air. FALSE.
Molecules with more heat move faster than molecules with less. Molecules in cold air therefore, will move slower than molecules in hot air.
