<h3>Hello i hope you are having a good day :) Question : Place the waves on the EM spectrum from longest to shortest wavelength: ultraviolet, infrared, gamma, radio, microwave, x – ray, visible?</h3><h3>So the first on is the shortest wave length would be 1. Radio waves then it would be 2. Microwaves Then 3. Infrared radiation 4. Visible light 5. Ultraviolet light 6. X rays 7.Gamma rays.</h3><h3>Hopefully this helps you.</h3>

Josh starts at a position of x=0 meters at the left side of the front of the classroom. Over the course of the class he walks ba

Aneli [31]

Answer:
180 meters

Explanation:
Josh walks 6 meters to the right and the 6 meters back. This means that in one time, Josh walks a total distance of 6+6 = 12 meters
Now, we are given that Josh walks this same distance 15 times.
Therefore, we will multiply this distance by 15 to get the total distance that he walks as follows:
Total distance = 12*15 = 180 meters

Based on the above calculations, Josh walks 180 meters over the course of the class

Hope this helps :)

A cable that weighs 8 lb/ft is used to lift 900 lb of coal up a mine shaft 650 ft deep. Find the work done. Show how to approxim

Harrizon [31]

Answer:

2275000 lb.ft

Explanation:

Let work done on the cable be denoted by: W_ca

Let work done on the coal be denoted by: W_co

Now, dividing the cable into segments, let x represent the length from top of the mine shaft to the segment.

Meanwhile let δx be the length of the segment.

We are told the cable weighs 8 lb/ft. Thus;

Work done on one segment = 8 × δx × x = 8x•δx

Therefore, work done on cable is;

W_ca = ∫8x•δx between the boundaries of 0 and 650

Thus;

W_ca = 4x² between the boundaries of 0 and 650

W_ca = 4(650²) - 4(0²)

W_ca = 1,690,000 lb.ft

Workdone on the 900 lb of coal will be calculated as;

W_co = 900 × 650

W_co = 585000 lb.ft

Thus,

Total work done = W_ca + W_co

Total workdone = 1690000 + 585000

Total workdone = 2275000 lb.ft

Newton observed the action of a prism on the white light and on red light. Because he did not control the event, this investigation of light was an observational study.

Hope this helps! (:
