Answer:

a) a = 43.11m/s^2

b) F = 40648.42N

Explanation:

We will use kinematics to calculate the average acceleration:

a = \frac{Vf-Vo}{t}

a = \frac{26.3-0}{0.61}

a = 43.11m/s^2

By dynamics:

F = m*a

F = 942.9*43.11

F = 40648.42N

Compare and contrast fluorescent and incandescent light bulbs.
dezoksy [38]

Incandescent light is a glowing white light produced by heat. An incandescent light bulb works by heating a filament in the bulb. Fluorescent light is a bright light produced by electricity flowing through a tube filled with ionized gas. Fluorescent light bulbs are more energy-efficient than incandescent bulbs
