Work Done = Force x distance
Since she exerted a horizontal force of 20N over a distance of 5m, the work done is 20N x 5m which is equals to 100 joules
- Some people view bacteria specimens with a 100x objective lens in order to see the smallest details.
- Others may use a 10x objective lens for more general purposes, such as examining stained slides or pictures.
- And still others may use a 40x objective lens to gain maximum resolution when viewing images of thick samples.
It is important to choose the appropriate magnification for your needs so that you can properly examine the specimen under study.
<h3>Why is the 100x objective lens necessary to see bacteria?</h3>
- Bacteria must, of course, be viewed at the maximum magnification and resolution possible because to their small size.
- Due to optical restrictions, this is approximately 1000x in a light microscope.
- To improve resolution, the oil immersion method is performed. This calls for a unique 100x objective.

Answer:
The velocity of the arrow after 3 seconds is 30.02 m/s.
Explanation:
It is given that,
An arrow is shot upward on the moon with velocity of 35 m/s, its height after t seconds is given by the equation:
We know that the rate of change of displacement is equal to the velocity of an object.
Velocity of the arrow after 3 seconds will be :
So, the velocity of the arrow after 3 seconds is 30.02 m/s. Hence, this is the required solution.
A) red light
red lights are an example of an electromagnetic wave. visible lights are the only electromagnetic waves we can actually see on the spectrum. red, in particular has the biggest wavelength.
b) ocean waves
ocean waves are not an electromagnetic wave. in fact, it’s a mechanical wave. electromagnetic waves can travel through a vacuum, that is empty space, but mechanical waves cannot.
c) sound waves
sound waves are also not an electromagnetic wave. it’s a mechanical wave. you cannot hear electromagnetic waves.
d) earthquakes
an earthquake is also not an example of electromagnetic waves. it’s a mechanical wave.
hope this helps!
Answer:
1525 meters above ground
Explanation:
So to do this you will need to write this in slope intercept form or 
. So 650 would be the b, 175 would be the m, and the x would be 5 so the equation would be 
so if you solve or simplify the equation you will get 1525 meters above the ground and that would be our final answer.
