Explanation:
gravitational force or gravity is the force of attraction between objects that have mass.
frictional force is the forec that opposes motion (movement) when two surface are in contact. (acts in the opposite direction of motion)
so to sum it up,
- gravtional force is the force of attraction between objects that have mass.
- objects on the earth have weight because of gravitational force between them and the earth.
frictional force
- oppose motion
- slow down and stop moving objects and;
- produce heat
hope it helps :)
Answer:
a) The car’s speed just after leaving the icy portion of the road is the first part
Explanation:
Answer:
Light takes 77 minutes to travel from the Sun to Saturn.
Explanation:
The equation for the average velocity can be used to estimate the time that light will take to travel from the Sun to Saturn. The average velocity is defined as:
(1)
Where v is the velocity, d is the covered distance and t is the time.
Equation 1 can be rewritten for t to get:
It is necessary to express the speed of light in terms of minutes:
⇒ 
<em>Km/min </em>
It is known that light takes 8,3 minutes to go from the Sun to the Earth, where the distance between each other is 150.000.000 Kilometers.
Answer:
-55 degrees c
Explanation:
because negative numbers work in reverse and that makes -55 actually lower.
It says: The bigger the distance between objects the smaller the gravity between them.
