<u>Answer</u>
9.82 × 10⁸ ft/s
<u>Explanation </u>
A number written in scientific notation is in the form'
A × 10ⁿ
Where 1 ≤ A < 10 and
n ⇒ is an integer.
982,080,000 = 9.82 × 100,000,000
= 9.82 × 100,000,000
= 9.82 × 10⁸ ft/s
Transverse waves occur when a disturbance causes oscillationsperpendicular (at right angles) to the propagation (the direction of energy transfer). Longitudinal waves occur when the oscillations are parallel to the direction of propagation.
Answer: a. How the mass of an extended object is distributed about a rotation axis
Explanation: Moment of inertia is defined as the measure of the rotational inertia of a solid object, it is a quantity that defines the torque needed to reach a desired angular acceleration around a given rotation axis, and it depends mainly on the mass distribution of the object, so the correct answer is: "how the mass of an extended object is distributed about a rotation axis"
