1.) Calculate the force of gravity between Earth (mass = 6.0 s 1024 kg) and Venus (mass = 4.9 s 1024 kg) when they are at their closest distance from
each other, 3.8 s 107 km.

2.) Calculate the force of gravity between a car (mass = 2.3 s 103 kg) and a
man (mass = 68 kg) when the man is standing a distance of 5.0 m from
the car.

3.) Calculate the force of gravity that Saturn (mass = 5.7 s 1026 kg) exerts
on a woman on Earth (mass = 61 kg) when Saturn is closest to Earth,
1.2 s 109 km.

Not what goes around on earth but the universe too.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

Supply is the markets term for selling a specific quantity of products at various prices. the law of supply and demand is the one which affect the pricing and also the quantity the market is able to produce or make available.

Ibelieve the answer is d. densityhope my answer has you : )
