Answer:
A derived unit is a unit that results from a mathematical combination of SI base units. We have already discussed volume and energy as two examples of derived units.
Answer: The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Answer:
The nucleus of an atom is made up of positively charged protons and neutrally charged neutrons. The nucleus determines which element an atom is, based on the number of protons. For example, only Oxygen has 8 protons, Carbon has 6 protons, etc. The nucleus is about 1/100,000 of the size if the whole atom.
