Gravitational force between two masses is given by formula
here we know that
now from the above equation we will have
so above is the gravitational force between car and the person

Decomposing - When plants and animals die, they decompose. This process uses up oxygen and releases carbon dioxide. Rusting - This is also called oxidation. When things rust they use up oxygen.
Answer:
9 and 3 N
Explanation:
Forces in the same direction sum up to produce the resultant force;
One force subtract the other will give the resultant force when they are in opposite directions;
Lets say one direction is forwards and the opposite backwards;
We have one force, let's say force A, in the forwards direction and another force, force B, acting in the same (forwards) or opposite (backwards) direction;
If B is acting in the same direction, then the resultant force (in this case) will be as follows:
A + B = 12
If B is acting in the opposite direction, then the resultant force will be as follows:
A - B = 6
Summing the two equations will allow us to solve for A:
A + B + (A - B) = 12 + 6
2A = 18
A = 9
Substitute this into either of the above equations and we can solve for B:
(9) - B = 6
B = 9 - 6
B = 3
Astronauts brought back 227kg of rock samples from the moon.
<h3>
Who is an astronaut?</h3>
A person who has been trained, outfitted, and sent into space by a human spaceflight program to serve as a commander or crew member is known as an astronaut (from the Ancient Greek words (astron), meaning "star," and (nautes), meaning "sailor"). The word is occasionally used to refer to anyone who flies into space, including scientists, politicians, journalists, and tourists, despite the fact that it is typically only designated for professional space travelers.
600 astronauts have made space flights since 1961. Up until 2002, only governments—either the military or civilian space agencies—sponsored and educated astronauts. A new class of astronaut was introduced in 2004 with the suborbital flight of the privately funded SpaceShipOne: the commercial astronaut.
Explanation:
1kg=2.20lb
500lb=(1/2.20*500)kg
500lb=227kg
