<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.

The radius of a helium atom 4.8 times bigger then the radius of an alpha particle.
<h3>What is
alpha particle?</h3>
The structure of alpha particles, also known as alpha rays and alpha radiation, is similar to that of the helium-4 nucleus and has been made up of two protons as well as two neutrons bonded together.
<h3>What is
helium?</h3>
For welding metals like aluminum, helium was utilized as an inert gas environment. It is also employed in rocket propulsion.
The radius of a helium atom 4.8 times bigger then the radius of an alpha particle. More precisely than it's ever been, the diameter of the helium atom's nucleus, the alpha particle, had also been measured. Outcomes just point to a size of 1.6782 femtometers, 4.8 times more accurate than earlier readings.

We can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.
<h3>How we can calculate the thickness using screw gauge?</h3>
We can determine the width/thickness of a coin by using a screw gauge because screw gauge is an instrument that measures thickness of an object that are very thin. First we can placed the coin in between the teeth of the gauge and then move the gauge until the coin can be held tightly. After that note the reading on the scale.
So we can conclude that we can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.

Answer:
1.) Liquid
2.) Low
3.) Molecular
4.) Surface tension
5.) Solvent
Explanation:
Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does
not experience large temperature changes because liquid water has a
LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water
molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can
dissolve many different substances.
