Explanation:
We have,
Spring constant of the spring, k = 165 N/m
Mass, m = 2 kg
It is required to find the period of the mass-spring system. For the spring mass system, the period is given by :
The frequency of vibration is reciprocal of its time period. So,
So, the period of the mass-spring system is 0.69 s and frequency is 1.44 Hz.
It would be 0.25 meter or one fourth of a meter
Answer:
The density of salt water is more than that of density of fresh water, so so salt and fresh water makes a difference in floating of ships.
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.
Answer:
The answer is 1020 meters.
Explanation:
The values given by the problem are:
1. T= The falling time of the rock [Seconds]
2. H=The sound velocity constant [meter/second]
The Velocity normal formula is
V=H/T
340=H/3
340*3=H
This solution considers the physic of the traveling wave sound but not really the rock falling problem, because the problem ask for the height of the cliff not even more.
