Answer:
C. The decrease in speed as the wave approaches shore.
Explanation:
The waves break when approaching the shore because the depth decreases. Thus, the wave travels more slowly and increases its height. There comes a time when the part of the wave on the surface travels faster than the one that travels under water, the ridge destabilizes and falls against the ground.
Kinetic energy means movement. This means that the more something moves, the more kinetic energy it will have! And the faster something moves, the more heat it produces! Altogether, this means that the more Kinetic energy something has, the hotter it will be!
The opposite is also true. The less something moves, it will have less Kinetic energy and the colder it will get.
If you're having trouble understanding this, think of it like how the particles in water move compared to how the particles in ice move. The particles in water are free flowing and can move wherever they want. If they get colder, they won't move as much, and eventually they'll stop flowing around, forming a solid and staying colder than the water will get.

Answer:
Average speed of the car A = 70 miles per hour
Average speed of the car B = 60 miles per hour
Explanation:
Average speed of the car A is 
(Equation A) and Average speed of the car B is 
(Equation B), where 
and 
are the distances and 
and 
are the times at which are travelling the cars A and B respectively.
We have to convert the time to the correct units:
1 hour and 36 minutes = 96 minutes
From the diagram (Please see the attachment), we can see that at the time they meet, we have:
(Equation C)
(Equation D)
From Equation A and C, we have:
208-x+16 = x
208 + 16 = 2x
x = 112 miles
Replacing x in Equation A:
Replacing x in Equation B:
Answer: position (x) and time (t)
Explanation:
A body is said to be in motion when its position changes with time with respect to a stationary observer.
Following are the types of motion:
<u>Uniform motion</u>: When equal amount of distance is covered in equal intervals of time.
<u>Non-Uniform motion</u>: When unequal amount of distance is covered in equal intervals of time.
Motion can be of the following types as well:
<u>Rectilinear motion</u>: when object moves in a straight line.
<u>Circular motion</u>: when object moves in a curved path.
<u>Periodic motion</u>: when motion repeats itself in fixed intervals of time.
Thus, in order to define motion, only two variables are required: position and time. Measuring these variables can determine whether the object is in motion or not and the type of motion.
