Answer:
Each part of the spectrum has a different range of wavelengths (which correspond to frequency, color, and energy) at which you can find it.
Answer:
0.038 m/s, 0.0096 m/s²
0.101
0.103
Explanation:
The speed is given by
v = 2πr / T
v = (2 * π * 0.15) / 25
v = 0.9426 / 25
v = 0.038 m/s
Acceleration, a is given by
a = v² / r =
a = 0.038² / 0.15
a = 0.001444 / 0.15
a = 0.0096 m/s²
Ratio of apparent weight to true weight at the top
w = m (g - a) / (m g)
w = 1 - a/g
w = 1 - 0.0096 / 9.81
w = 0.9904 / 9.81
w = 0.101
Ratio of apparent weight to true weight at bottom
w = m (g+a)/ (m g)
w = 1 + a/g
w = 1 + 0.0096 / 9.81
w = 1.0096 / 9.81
w = 0.103
Answer:
Loudness
Explanation:
In acoustics, loudness is the subjective perception of sound pressure.
22.5 m/s
This is because the puck will not slow down, and maintain a constant velocity.
