Answer:
Explanation:
Check the attachment.
By the definition of the simple harmonic motion,
The motion of a particle whose acceleration is
1. Always directed towards the center of the motion.
2. Proportional to the distance from center of the motion.
We get, a ∝ -x
where
a = acceleration
x = distance of the particle from center of the motion
- sign says acceleration is in opposite direction of motion
Check the other attachment for proof of a = -ω²x (or a = -ω²y)
x and y are both use to denote distance from center of the motion

Answer:
Known variously as the Newcomb–Benford law, the law of anomalous numbers, or the first-digit law, Benford's Law is the observation that the first digit in many real-world collections of numerical data will be tiny, as shown by the example of the first-digit law.

Hope it helps:)
Assuming that they are
pulling the space shuttle straight up, and that this is done on the surface of
the earth, where gravity is equal to 9.8 m/s^2. So taking the average pull force
of a person to be 110 kg, then: <span>
110 kg/person * 9.8 m/s^2 = 1078 kg*m/s^2, or 1078 N/person
(Newtons). </span>
1 Newton is about 0.225
lb. So, 1078 N/person * 0.225 lb/N = 242.34 lb/person. <span>
So if the space shuttle weighs 4,500,000 lb, then it would
take 4,500,000 lb / (242.34 lb/person) = 18,569 people. </span>
Answer:
<span>18,569 people</span>
Au, since it takes the least amount of energy per gram to change
