Gravitational force = Gxm1xm2 /r^2
This equation depends only upon object's masses and distance between them. So option b is correct
Answer: <u>Centrifugal Force </u>
Explanation:
The force that pulls out from the center on a body in circular motion is called centrifugal force and it increases with acceleration. Centrifugal force results in strong outward pull on your vehicle.
Momentum = mass x velocity = 91x9 = 819 kg-m/s.
Answer:
Exposure to the Atmosphere
Composition of Rock
Surface area of the rock
Climate
Time
Explanation:
Exposure to the Atmosphere - how much of the rock mass is exposed to the environment affects how quickly the rock will be weathered by that very environment
Composition of Rock - what kind of minerals the rock is made of, how easy it is for those minerals to disintegrate and how quickly the react with water and air.
Surface area of the rock - a rick that has a wider surface or smaller pieces is more exposed than one that is a lump. A larger surface area increases the rate of weathering
Climate - if a rock is an area where there are high temperatures or very low temperatures, the rate of weathering is likely to increase. A similar point can be made about a region that experiences a lot of rain.
Time - the longer the rock is exposed to harsh conditions, the more it will experience weathering
