I don't really know
Explanation:
So I'm going to look it up
Answer:
It is important to have a range of tools that can measure all parts of the electromagnetic spectrum because electromagnetic spectrum have different radiations such as infrared, visible light, ultraviolet, radio waves, microwaves, X-rays and gamma rays. Each of these radiation requires different instrument for their measurement. So that's why a range of tools are needed to measure electromagnetic spectrum.
Answer:
Displacement = 20 m
Explanation:
Given that,
Kyle runs 20 m north, 20 m west and then 20 m south.
We need to find Kyles's total displacement.
Total distance = shortest path covered by Kyles.
The net displacement of Kyle is 20 m in east direction. Hence, this is the required solution.
