Boyles law
Pressure and volume are inversely proportional as the new variable changes from the known.

So 40.0 mL is the new volume as it is compressed.
A negative ion is a atom that has an extra electron, but the same # of protons
Answer:

Explanation:
Given that,
The speed of a driver, v = 80 km/h = 22.22 m/s
The mass of the truck, m = 2000 kg
We need to find how much internal energy is produced. The internal energy produced by a truck is its kinetic energy and it is given by :

or

So,
of internal energy is produced.
Answer:
