<span>Plate tectonics is the theory that the earth's crust is broken up into plates
that float on top of a hotter and more fluid layer below. Evidence to
support this theory has been uncovered through the study of the earth's
past magnetic field, known as paleomagnetism.</span>
10+8 = 18
5+2 = 7
18-7 = 11

<span>A cart travels down a ramp at an average speed of 5.00
centimeters/second. What is the speed of the cart in miles/hour? </span>
To solve this problem we have set the conversion values to
determine the product during the conversion process.
<span><span>
1. </span>1
centimeter = 0.00000621371 mile</span>
<span><span>
2. </span><span> 1 hour = 60 minutes</span></span>
<span><span>3. </span><span> 1 minute = 60 seconds</span></span>
Thus, we shall have
<span><span>1. </span>5 cm x 0.00000621371
mile/1cm = 0.000031069 mi</span>
<span><span>2. </span>0.000031069
seconds x 1 hr / 3600 = 0.111846815 miles / hr</span>

<h3><u>Answer;</u></h3>
Energy
<h3><u>Explanation;</u></h3>
- A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
- <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
- <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
- <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.
