A spring with a spring constant of 165 N/m is attached to a 2.0 kg mass and set into motion.
marin [14]

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 :

T=2\pi \sqrt{\dfrac{m}{k} }\\\\T=2\pi \sqrt{\dfrac{2}{165} }\\\\T=0.69\ s

The frequency of vibration is reciprocal of its time period. So,

f=\dfrac{1}{T}\\\\f=\dfrac{1}{0.69}\\\\f=1.44\ Hz

So, the period of the mass-spring system is 0.69 s and frequency is 1.44 Hz.

Can 2 atoms have different numbers of neutrons and the same number of protons and be from different elements?
zimovet [89]
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.

A rock is dropped from a sea cliff, and the sound of it striking the ocean in heard 3.0.s later. If the speed of sound is 340m/s
Ahat [919]

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.
