What amount of force will keep a 6-kg object moving with a constant velocity of 2 m/s

Ineed with these 2 questions. you.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
