Answers

Answer 1
Answer:

Answer:

6.  microwave

Explanation:

The answer is microwaves because microwaves have the longest wavelength (of the listed ones) and therefore the lowest energy.

The measure of the average kinetic energy of a substance is called the________?

Answers


Temperature is the measure of average kinetic energy of the substance. Temperature rises when the average kinetic energy increases. Kinetic energy is related to the movement of the molecules within the substance. In this case, temperature and kinetic energy are always proportional to each other
pretty sure its the temperature

Johannes Kepler is best known for his work on planetary motion.
a. True
b. False

Answers

Answer: True.

Kepler was an astronomer, astrologer and mathematician. He was an apprentice of Tycho Brahe, other big (maybe the biggest) astronomer of their time.

Kepler is best known for his 3 laws of planetary motion.

1) the orbit of a planet is an ellipse with the Sun at one of the two foci

2) A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time

3) The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
Truer words are seldom if ever written.

How dense the medium is in the compression part of the wave, and how

Answers

How dense the medium is in the compression part of the wave and how rare the medium is in the rarefaction part of the wave is a measure of the longitudinal wave's amplitude.

What is the temperature of a gas in which the atoms are moving very very slowly?

Answers

Cold.
Example: A frozen object (such as ice) is solid. Its molecules move extremely slow because the object itself isn't moving... It's like the skin on your bod... Imagine that wiggling and writhing on your bones. It's not like a gas, that can move freely and has no specific form or hold.
So again, the answer is Cold. 

A skier starting from rest accelerates in a straight line down a 43,000 m slope at 1 m/s. How fast were they moving after 5 s?

Answers

Answer:

5m/s

Explanation:

The skier accelerates at 1 m/s, then, the acceleration is:

a=1(m)/(s^2)

to find the speed after 5 seconds you use the following formula:

a=(v-v_o)/(t)

but vo = 0m/s because the skier is at rest at the beginning.

You do v the subject of the formula:

v=at=(1(m)/(s^2))(5s)=5(m)/(s)

hence, the velocity is 5m/s

Imagine the door to a theatre is opened and you are standing outside. How is it possible that you can hear the sound of the movie or play even if you cannot see the screen or stage ?A) reflection only happens with sound waves not waves of light so the sound waves bounce out to your ears. B) the sound waves refract as they move from one medium to another C) the darkness in the theatre absorbed light but not sound so you can hear D) the sound waves diffract much more than the light waves so try bend and spread as they move through the doorway.
