Question

Which scenario is an application of Newton's Third Law of Motion?



A. A car traveling 60 mph was heading north on the road. A truck was heading 60 mph south in the same lane of the same road. When they collided, the car moved a greater distance backward than the truck did.


B. Two go-carts are on the start line. One is pushed and continues to roll forward. The second lacks someone to push it and remains stationary at the start line.

Answer 1

C. A cruise liner has lost power and can't get into port. Two tug boats push at the back of the ship and the ship begins to move forward toward the dock.


D. As the space capsule entered the earth's atmosphere, its acceleration toward the earth increased.

Answer 2

first one

Answer 3

alright can you help me with one more

Answer 4

yes

Answer 5

am trying my best

Answer 6

A new solar system with two planets of equal mass - Planet X and Planet Y - is discovered. Planet X is closest to the sun.



What is the sun's gravitational pull on Planet Y as compared with Planet X?



A.The sun's gravitational pull on Planet Y is equal to its gravitational pull on Planet X because distance does not affect the sun's gravity.


B.Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is less than the sun's gravitational pull on Planet X.


C.Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is more than the sun's gravitational pull on Planet X.


D.The sun's gravity repels Planet Y with more force than it repels Planet X, which is why Planet Y is farther away.

Answer 7

I guess 1st one not sure

Answer 8

force of gravity always depends on the mass and the distance of two objects.
according to Newton's universal gravitation, the force of gravity to the product of the masses is directly proportional and inversely proportional to the square of distance between them.

Therefore, since planet Y is farther than planet x, it should have a lesser force of attraction with the sun :)
