Sunlight is an example of EM waves. Other examples
include radio waves, microwaves, and X-rays. I hope this helps.
Answer:
2.58 m/s
Explanation:
We can use the following equation of motion to find out the constant acceleration of the block:
where v = 3.8 m/s is the final velocity after it has traveled 7.4 m, is the initial velocity of the block when it starts from rest, , and is the distance traveled.
We can use the same motion equation to calculate block speed at the end of 3.4m track
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as we now understand Earth's gravity pulls down anything that isn't held up by some other force
