Answer:
It's mileage is 5.95 km per liter.
Since the half life of the radioactive isotope is 4,000 years, after 4,000 years the amount of the isotope would decrease by half. (Hence the name, half life.) So, after 4,000 years, there would be half of the isotope left in the fossil.
Answer:

Explanation:
hello,
the combined gas law equation is given as;

This combined gas law is gotten from the combination of Charles' law, Boyle's law and the Pressure law.
At constant pressure(this means the pressure is unchanged or fixed and this means the pressure is eliminated), we have:

At constant volume(we eliminate the volume since it is fixed or unchanged), we have;

At constant temperature (we also eliminate temperature), we have
.
thus from the options provided in the question the right answer will be

Electromagnetic waves can be transferred through empty space
