A. Increase until it reaches it's maximum. Sound travels through air and as the amount of air in the jar increases, the loudness or amplitude of the bell increases until it reaches it's maximum at normal air pressure.
I think it is A.. but then again im not sure
Answer: it turns into energy
Explanation: In a nuclear fusion reaction, two reactants combine, and form new products. But the mass of the products is less than total mass of the reactants. This is because a part of mass is lost as energy. This can be seen in an example shown below. You can see that mass is of the products is less than that of the reactants.

The average force on the squid during the ejection of 0.60 kg of water at a velocity of 15.0 m/s in 0.15 seconds is 60 N.
We can calculate the average force with the average acceleration as follows:
(1)
Where:
- m: is the mass of water = 0.60 kg
: is the average acceleration
The <em>average acceleration</em> is given by the change of velocity in an interval of time
(2)
Where:
: is the initial velocity = 0 (the squid is at rest)
: is the final velocity = 15.0 m/s
: is the initial time = 0
: is the final time = 0.15 s
Now we can find the <em>average force</em> after entering equation (2) into (1)
Therefore, the average force on the squid during the propulsion is 60 N.
