That ratio is called"efficiency". It doesn't need to be a percent.
It can just as well be a fraction or a decimal number.
The actual weight of the gas = apparent weight + weight.
The actual weight =
+ W
Given that a plastic bag is massed. It is then filled with a gas which is insoluble in water and massed again.
If the apparent weight of the gas is the difference between these two masses, then let the apparent weight = 
The gas is squeezed out of the bag to determine its volume by the displacement of water. Since
density = mass / volume
The density of water is 1000 kg/
we can get the mass of the gas by making m the subject of the formula.
W = mg
The actual weight of the gas = apparent weight + weight
That is,
The actual weight =
+ W

Answer:
<em>The final speed of the second package is twice as much as the final speed of the first package.</em>
Explanation:
<u>Free Fall Motion</u>
If an object is dropped in the air, it starts a vertical movement with an acceleration equal to g=9.8 m/s^2. The speed of the object after a time t is:

And the distance traveled downwards is:

If we know the height at which the object was dropped, we can calculate the time it takes to reach the ground by solving the last equation for t:

Replacing into the first equation:

Rationalizing:

Let's call v1 the final speed of the package dropped from a height H. Thus:

Let v2 be the final speed of the package dropped from a height 4H. Thus:

Taking out the square root of 4:

Dividing v2/v1 we can compare the final speeds:

Simplifying:

The final speed of the second package is twice as much as the final speed of the first package.
Answer: The free ending nerves.
Explanation:
At our fingertips, we have a lot of sensory nerve endings, that give information about changes that occur at your skin.
Like touching something with a given texture, feeling pain, or noticing changes in temperature.
There are different types of nerve endings, particularly the ones responsible to detect pain, and temperature are the free nerve endings.
So Marcus may have the free nerve endings damaged.
