Will give brainliest f=ma is newton's 2nd law. how much force would it take to move a 10 kg mass so that it accelerates to 20 m/s2 ? formula: force = mass x acceleration a) 20 newtons of force b) 200 newtons of force c) 2,000 newtons of force

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Give an example in which the electrical energy changes to light energy

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
