Describe why gravity is not the same on all planets and why 2 tennis balls on Earth will always fall toward Earth and not attract each other.
Alright Dude, If that worked for you... dont forget to give THUMBS UP.(that will work for me!)
If I missed something feel free to leave a comment.
atleast before giving downvote.
and, Thanks for using homeworklib- Smarter way to study.

1. All the planets orbit the Sun in the same direction. This is strong evidence that: Group of answer choices None of these is correct. We do not have any idea yet why the planets are orbiting in the same direction. the solar system resulted from the collision of two medium-sized stars. after the planets formed, collisions between them eventually caused them all to move in the same direction. the planets were formed elsewhere in the galaxy and were later...
1. If gravity on Earth provides a constant acceleration of 9.8m/s2 why aren't we all moving faster and faster toward the center of the Earth all the time? 2. If Magnus Magnuson is in a tug of war match, and he is pulling on the rope with a force of 1265 N, with how much force is the rope pulling on him? 3. Describe the type of force applied by a flat road to a tire when a car is...
Consider the following table which shows different baskets of tennis balls: (a) List all samples of size 2, and compute the mean of each sample. (b) Compute the mean of the distribution of the sample mean and the population mean. Compare the two values. (c) Compare the dispersion in the population with that of the sample mean.

"apparent weightlessness” Which of the following statements explains why astronauts seem weightless while in an orbiting spacecraft? a) There is no gravity in space b) They are in a state of free fall, accelerating toward the earth at the same rate as the spacecraft c) They are far enough from the earth that gravity is not able to reach them d) None of the above

Two tennis balls are dropped through the air from a tall building. One of them is filled with lead pellets making it heavier than the other. In presence of air-resistance, the ball to reach the ground first is the ---- a. Lead filled tennis ball b. Insufficient infomation c. Regular tennis ball d. both hit the ground at the same time 2. As you drive in your car at 22.5 mi/h, you see a child’s ball roll into the street ahead...

Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...
The cost of manufacturing x tennis balls is C(x)=0.1x^(2)+25x+1000 if 0<x<700 . a) Find the average cost function C(x) . b) Identify all intervals on which C(x) is increasing. c) Identify all intervals on which C(x) is decreasing. d) Identify the x-coordinate for all local extrema of C(x) .
