Explanation:
Vectors are quantities that has both magnitude and direction. A vector is described in terms of quantity and the direction it is headed.
There are different forms of vectors that are used in our daily life.
- When we describe the motion of a car and the direction it is heading, we are simply talking about its velocity which is a vector.
- When we say James treks 2km from his school to the house everyday, we are simply describing his displacement.
- When we apply a force to push the table from one corner of the room to another point, is simply a vector
- When we change position, it is a vector application.
Gravity is an example of friction. If we didn't have gravity, we would be flying all over the place. Also, friction keeps us from sliding on the ground and falling.
Xrayssssss because they are the closest to gamma rays, and they have the highest frequency
Answer:
Explanation:
speed of light = 3 x 10⁸ m /s .
distance between moon and the earth = 3.77 x 10⁵ x 10³m .
Time taken by light to cover the distance
= distance / speed
= 3.77 x 10⁸ / 3 x 10⁸
= 1.256 s
