Answer:
The average angular acceleration is -2.628 rad/s²
Explanation:
Counterclockwise = positive
Clockwise = -negative
Given;
initial rotation of the flywheel, θ₁ = 6.55 rotation/s
final rotation of the flywheel, θ₂ = - 2.19 rotation/s
The average angular acceleration is given by;

Therefore, the average angular acceleration is -2.628 rad/s²
A geologist is studying rock layers in an old river bed, and he finds a fossil of a fish and a horsetail rush in the same rock layer. According to the law of faunal and floral succession, the geologist can assume that the rock containing the fossils may date back as far as the <span>Devonian period</span>.
Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal
Answer:
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Explanation:
Protons are positively charged and neutrons are neutral whereas electrons are negatively charged.
