A0.5-kg ball accelerated at 50 m/s2 . what force was applied?

The answer is Force is equal to 25N

Explanation:

1) Taking into account Newton's second law, which expresses that the acceleration that a body acquires is directly proportional to that resulting from the forces acting on it, and has the same direction as that resulting.

2) This law is expressed with the formula F = ma where (F) represents force, (m) represents mass and (a) represents acceleration.

3) knowing this we can replace the values given in the problem and solve:

F = (0,5kg)(50m/s^2)

F = 25N

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
