Answer:
The frequencies are 13.8 Hz, 75 Hz, 12 Hz and 63.8 Hz.
Explanation:
Given that,
The frequency in r.p.m
Suppose, we find the frequency in hz.
We know that,
One r.p.m is equal to the one divided by 60 Hz.
We need to calculate the frequency in Hz
Using formula for frequency in Hz
For f₁,
For f₂,
For f₃,
For f₄,
Hence, The frequencies are 13.8 Hz, 75 Hz, 12 Hz and 63.8 Hz.
Answer:
left side
Explanation:
It's smaller in length but still has a pretty close slope to the right side.
We can ignore all that business about resting on the rock and
rolling down part of the way and then resting on the moss.
Its potential energy right now doesn't depend on what happened
to it yesterday. We don't care.
All we care about is that we're walking along in the park and we
notice a 1.5kg rock lying in moss 10 meters above the ground.
Gravitational potential energy
= (mass) · (gravity) · (height)
= (1.5 kg) · (9.8 N/kg) · (10 m)
= 147 (kg · N · m / kg)
= 147 joules
