Explanation:
A general wave function is given by:
A: amplitude of the wave = 0.075m
k: wave number
w: angular frequency
a) You use the following expressions for the calculation of k, w, T and λ:
b) Hence, the wave function is:
c) for x=3m you have:
d) the speed of the medium:
you can see the velocity of the medium for example for x = 0:
Answer:
Explanation:
Volume can be found by dividing the mass by the density.
The mass is 100 grams and density is 0.920 grams per cubic centimeters.
Therefore,
Substitute the values into the formula.
Divide. Note that the grams, or "g" will cancel each other out.
The volume of the ice cube is 108.697652 cubic centimeters.
