Answer:
a
Explanation:
the answer is a because it is feasible
The arrows in models of magnetic and electric fields show both their magnitude and direction.
In Physics, a vector refers to a quantity that has both magnitude and direction. Hence, a vector always points in a given direction. The direction in which the arrow points is the direction of the vector in space.
In models of magnetic and electric fields, field vectors depicted by arrows because they represent both their magnitude and direction. The length of the arrow shows magnitude.

Answer:
The answer is C.
Explanation:
Let's take a glass of water as an example. Now, shine a flashlight on it. See it bend the light into a rainbow? That is a example of refraction. When the light enters the water, the water actually slows down and changes its direction, causing the light to come out the other side in a different way. Since water is very dense, it can bend the water and make it different.
Answer:
Time = 801.802 secs.
Explanation:
Speed can be defined as the rate of change in the magnitude of distance with respect to time. It is a scalar quantity because it only has magnitude but no direction.
Given the following data;
Average speed = 11.1m/s
Time =?
Distance = 8900m
![Speed (S) = \frac{distance}{time}](https://tex.z-dn.net/?f=Speed%20%28S%29%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
![S = \frac{d}{t}](https://tex.z-dn.net/?f=S%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
Making time (t) the subject of formula, we have;
![Time (t) = \frac{d}{s}](https://tex.z-dn.net/?f=Time%20%28t%29%20%3D%20%5Cfrac%7Bd%7D%7Bs%7D)
![Time (t) = \frac{8900}{11.1}](https://tex.z-dn.net/?f=Time%20%28t%29%20%3D%20%5Cfrac%7B8900%7D%7B11.1%7D)
Time = 801.802 secs.
<em>Hence, the time the biker takes to cover the segment is 801.802 seconds. </em>
