Answer:
The new findings support the theory that walking first arose underwater, preceding the move onto land and the development of toes and limbs adapted to land perambulation.
A single fixed pulley is used to lift load by changing the direction of the lifting force. Even though a single fixed pulley has no mechanical gain in that, the effort applied is greater than the load, it is preferred in use since you do not have to pull or push the pulley up and down.
The average Kenectic energy
Answer:
The pressure increases.
Explanation:
According to Avogadro's principle, equal volume of gases contains the same number of moles. From the reaction equation, there is a decrease in the total number of moles from reactant to product indicating a decrease in volume (as per Avogadro) and an increase in pressure according to Boyle's Law-Volume is inversely proportional to pressure.
Explanation:
Here are the answers. Do note that I had to convert the enthalpy to joules and temperature to Kelvin to make the unit for entropy work out.
