Crude oil, coal, natural gas. All of these pollute the Earth when there are consumed and have a certain amount available. Renewable resources are infinite in value.

Answer:
0.68 kg-m²
Explanation:
F = Force applied by the muscle = 2615 N
r = effective perpendicular lever arm = 2.85 cm = 0.0285 m
α = Angular acceleration of the forearm = 110.0 rad/s²
I = moment of inertia of the boxer's forearm = ?
Torque is given as
τ = I α eq-1
Torque is also given as
τ = r F eq-2
using eq-1 and eq-2
r F = I α
(0.0285)(2615) = (110.0) I
I = 0.68 kg-m²
Answer:
100 iPods
Explanation:
The deciBell scale is logarithmic, and thus, it turns multiplying into adding.
Initially, it was the Bell scale, purely logarithmic, where "times 10" is translated into "plus 1" (just like normal logs). However, the steps became too big and so they divided the Bell in 10 parts, the deciBell.
The levels above could well have been called 10B and 12B.
Usually, we define the dB scale for intensity as:
I(dB) = 10•log(I)
Thus,
I = 10^(I(dB)/10)
Now 120 dB gives us units of I = 10^(120/10) = 10^12 Pa (assume the dB are measured to 1 Pa) and 100 dB is 10^10 Pa.
Thus, we would need 100 ipods to get the same intensity
