Answer:
The speed is 1.52 m.
Explanation:
Given that,
Displacement =0.270 m
Distance = 0.130 m
Suppose a 0.321-kg mass is attached to a spring with a force constant of 13.3 N/m.
We need to calculate the angular velocity
Using formula of angular velocity

Put the value into the formula


We need to calculate the velocity
Using formula of velocity

Put the value into the formula


Hence, The speed is 1.52 m.
Answer:
Explanation:
12.)
A. Opposite poles attract
B. Same poles repel
13.)
IDK
B. Deflate because volume is inversely proportional to temperature
Answer:
The amplitude of the wave is 0.02 m.
Explanation:
Given that,
Maximum speed = 2.0 m/s
Maximum acceleration = 200 m/s²
We need to calculate the angular frequency
Using formula of angular frequency

Put the value into the formula


We need to calculate the amplitude of the wave
Using formula of velocity


Put the value into the formula


Hence, The amplitude of the wave is 0.02 m.
