1 is 0n I believe 2 8n or 2n 3 would be 10n 4 is 0n or 12n
Answer:
The number of molecules displaced in a vibration makes the amplitude of a sound.
Nine times more (squared speed)
Answer:
t = 0.1111 s
Explanation:
Let's reduce the magnitudes to the SI system
d = 120 mm (1m / 1000 mm)
d= 0.120 m
w = 540 rpm (2pi rad / 1 rev) (1 min / 60s)
w= 56.55 rad / s
When at maximum speed we can use angular kinematic relationships to find the time for a sperm revolution with zero angular acceleration
W = θ / t
t = θ / w
t = 2π / 56.55
t = 0.1111 s
