At first you have to convert your wavelength to meters:
75 cm = 0.75m
then you need to know the speed of sound - I've found that it is 340.29 m/s
and finally, you can use this equation:
λν = c
(0.75m) (f) = 340.29
f = 340.29 / 0.75
f=453.72 Hz
Both ends are held up by the watertight pockets which are much less dense than the water around it.
A muscle that assists the prime mover or helps stabilize the joint during movement would be a synergist.
Hope I helped!
Answer:
separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.
Answer:
y₀ = 10.625 m
Explanation:
For this exercise we will use the kinematic relations, where the upward direction is positive.
y = y₀ + v₀ t - ½ g t²
in the exercise they indicate the initial velocity v₀ = 8 m / s.
when the rock reaches the ground its height is zero
0 = y₀ + v₀ t - ½ g t²
y₀i = -v₀ t + ½ g t²
let's calculate
y₀ = - 8 2.5 + ½ 9.8 2.5²
y₀ = 10.625 m
