Abook that has a mass of 0.5 grams is pushed across a table with a force of 20 newtons what is the acceleration of the book? a.10 m/s^2
b. 0.025 m/s^2
c.40 m/s^2
d.40 m/s

Explanation:

To solve this equation ,we need to apply Newton's second law. Which defines

Force = Mass* Acceleration

Mass  = 0.5 g = 0.5*10^-3 Kg

Force  = 20 N

Acceleration = Force / Mass

Acceleration  = 20 N /0.5*10^-3 Kg

Acceleration  = 40000 m/s^2

I believe you meant a mass of 0.5 Kg

In that case, the acceleration would be

Acceleration  = 40 m/s^2

Option C

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
