Answer:
So an object with mass is attracted to another object with mass, and the gravitational force is directly proportional to the masses of the two objects, and inversely proportional to the <em>square</em> of the distance between the two objects.
If distance were to increase, than the gravitational force would decrease. If mass were to increase, so would the gravitational force.
Explanation:
Answer:
750 mph, east
Explanation:
The jetliner is going from San Francisco to Chicago... so it's moving from West to East, at 600 mph, relative to the air.
The wind is also moving from West to East, at 150 mph.
Since both are going in the same direction, we combine the speeds by adding them to each other. If they were in opposite direction, we would subtract them.
So, 600 mph for the plane + 150 mph for the wind = 750 mph, going EAST.
Answer:
The magnitude of buoyancy force is equal to that of ball's weight.
Explanation:
Ball 1 is floating on water. Weight of ball 1 is Fg=m1g is acting vertically downward
Force of buoyancy FB = ρVdisg is acting vertically upward.
Net force acting on the ball is zero, FB=Fg
Answer
The magnitude of buoyancy force is equal to that of ball's weight.
