You have a vibrational degree of freedom that can be treated like a harmonic oscillator with a spacing between energy levels of 257.82 cm-1. What is the probability that this degree of freedom is in state 2 at a temperature of 689 K. Give your answer with at least 3 significant figures.

What determines the amount of inertia an object has

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.

An element becomes a positively charged ion when itloses protons. loses electrons. gains electrons. gains neutrons.
