1.Phases - Gas, liquid and solid. Gas, liquid, and solid are known as the three states of matter or material, but each of solid and liquid states may exist in one or more forms.
Answer:
The force exerted by the muscle is 852.27N
Explanation:
Force F exerted by the muscle is expressed as a function of the torque τ and the effective perpendicular arm r.
F = τ/r ... (1)
Where τ = moment of inertia I × angular acceleration α
τ = Iα ... (2)
Substituting equation 2 into 1 to get F will give;
F = Iα/r
Given the following parameters
I = 0.75kgm²
α = 37.5rad/s²
r = 3.30cm = 0.033m
F = 0.75(37.5)/0.033
F = 28.125/0.033
F = 852.27N
The force exerted by the muscle is 852.27N
Answer:
Explanation:
In order to answer this problem you have to know the depth of the column, we say R, this information is important because allows you to compute some harmonic of the tube. With this information you can compute the depth of the colum of air, by taking tino account that the new depth is R-L.
To find the fundamental mode you use:
n: mode of the sound
vs: sound speed
L: length of the column of air in the tube.
A) The fundamental mode id obtained for n=1:
B) For the 3rd harmonic you have:
C) For the 2nd harmonic:
