Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Explanation:

Electromagnetic waves are waves which can travel through the vacuum of outer space. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.

A box of cleaning supplies weighs 15 N. If the box is lifted a distance of 0.60 m, how much work is done?
Nady [450]
Work Done = force x displacement. So in this case the 15N is the force (because weight is a force) and 0.60m is the displacement. Therefore 15 x 0.6 = 9 Joules of work done (btw, work done can also be referred to as energy transferred)

A sample of lead has a density of 11.3 g/cm3 and a mass of 123 grams, what is the volume of the sample?
SVEN [57.7K]

Answer:

The answer is

<h2>11.18 cm³</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 123 g

density = 11.3 g/cm³

The volume is

volume =  \frac{123}{11.3}   \\  = 11.18181818...

We have the final answer as

<h3>11.18 cm³</h3>

Hope this helps you

ch3)2c(oh)ch2ch3 skeletal structure, Functional groups, compound type &amp; alcohol class if it’s an alcohol
xxTIMURxx [149]

The skeletal structure of an organic compound is an abbreviated representation of its molecular structure, they are quick and easy to draw.

For example, the following image shows the skeletal structure of a compound:

The peaks represent the carbons. We must remember that carbon can have a maximum of 4 bonds.

Now, I will show you how is the structure of this specific compound:

This is ternary alcohol, called 2-methyl-2-butanol. If you see carefully, you will notice that each carbon has 4 bonds. The functional groups present will be OH. The skeletal structure will be:

A crow flies 100 meters east in 5 minutes. What is the crow’s velocity?​
torisob [31]

<em>Answer:</em>  20 m/min east

<em>Explanation:</em>  The speed is distance divided by time

distance between start-point and end-point = 100 meters

<em>time to cover the distan</em>ce  =  5 minutes

100 m ÷ 5 min = 20 m/min east

y<u>ou have to add east since velocity is the measure of speed and direction and your answer needs to include the direction</u>
