Force is a measure of the interaction between bodies, mass is a measure of the amount of material in an object, weight is the gravitational force acting on a body (although for trading purposes it is taken to mean the same as mass) and load usually means the force exerted on a surface or body
The gravitational force exerted on the satellite is called the centrifugal force, the force keeping it orbiting to the planet. Its formula is F= mass times the square of the velocity all over the radius.Thus,
F = 2400 * 6670^2 * (1/8.92x10^6)
F = 11,970 N
I hope I was able to help you. Have a good day.
Answer: The object moves with constant velocity
Explanation:
In this velocity vs time graph we're dealing with Ap physics or regents physics. If we look at the slope we can see it is constant or not changing. Even so lets check the other answers and prove them wrong
The objects speed increases: This is wrong because the line shows a steady 5m/s with no change
The object is in free fall: If the object was in freefall the speed would be increasing as a result of acceleration due to gravity
The object moves with a constant speed: This seems to be the case since the slope or line doesn't change at all
The object stays at rest: Can't be right because the object is at a speed of 5m/s so we know its moving at least
The objects speed decreases: Again the line isn't going up or down so we can't say speed increases or decreases
Answer:
39.2 N
Explanation:
The weight of the bar in Newton's is given by
where m is the mass of the bar and is the acceleration due to gravity.
In this problem, the mass of the bar is m=4 kg, therefore its weight in Newtons is
