According to Newton’s second law of motion, force equals mass times acceleration (F = ma). Given that a car has a mass of 3,000 kg, how much force would be needed to accelerate it 2 m/s²?

A
1,500 N

B
6,000 N

C
3,000 N

D
1,000 N

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
