Answer:
<h2>The answer is option C</h2>
Explanation:
The work done by an object given it's distance and force can be found by using the formula
<h3>work done = force × distance</h3>
From the question
force = 20 N
distance = 10 m
The work done is
work done = 20 × 10
We have the final answer as
<h3>200 J</h3>
Hope this helps you

This is because the interaction between piece of paper and earth.is gravitational while that of piece of paper and rod is electrostatic
Answer: 4. Windy, whooping weather
Explanation: b/c it is!
The one that is false in this case is 3) All EMR can be seen. We cannot see EMR that is below visible light with the naked eye.
However with this question, one thing that I would like to point out is that EMR only travels at the speed of light when it is in a vacuum a.k.a. air. Otherwise it doesn't travel at the speed of light because it could be refracted.
Answer:
<em>Andrew's dog's speed was 1.89 m/s</em>
Explanation:
<u>Motion at Constant Speed</u>
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
This can be written as the formula below:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Andrew's dog run a distance of d=17 meters in a time of t=9 seconds, thus its speed was;
v = 1.89 m/s
Andrew's dog's speed was 1.89 m/s
