Answer:
Gravity
because it's factorised by mass of a body.
For other forces, they deal with charges of negligible mass and weights
<h2>
Answer:Stretched rubber band with an mass</h2>
Explanation:
Simple harmonic motion requires a restoring force.
Simple harmonic motion should be periodic.
Option A:
When a rubber band is stretched,the internal forces of the rubber band pulls the band inside.So,internal forces are the restoring forces in a rubber band.
The motion is periodic as well since the the rubber band makes to an fro motion expanding ans contracting.
So,this performs SHM.
Option B:
There is no restoring force and no periodicity.
So,this is not SHM.
Option C:
There is no restoring force and no periodicity.
So,this is not SHM.
Option D:
There is periodicity but no restoring force.
So,this is not SHM.
Well, it is also known as the transmission of fluid pressure. So, it is a principle in fluid mechanics that says that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such as the the pressure variations.
The combined acceleration of all the molecules of oxidized fuel as they emerge from the rocket's nozzles create the thrust that accelerates and propels the rocket
<u>Statement</u><u>:</u>
Jane does 5 joules of work when she closes her bedroom window. She applies a force of 6 newtons to do the job.
<u>To </u><u>find </u><u>out:</u>
The displacement of the window when she pulled it.
<u>Solution</u><u>:</u>
- Work done (W) = 5 J
- Force (F) = 6 N
- Let the displacement of the window be s.
- We know, the formula of work done, i.e., W = Fs
- Putting the values in the above formula, we get
- 5 J = 6 N × s
- or, s = (5 ÷ 6) m
- or, s = 0.83 m
<u>Answer</u><u>:</u>
She pulls the window by 0.83 m.
