Answer:
28.295244 MeV
Explanation:
= Mass of proton = 1.007276 u
= Mass of neutron = 1.008665 u
= Mass of electron = 0.000549 u
Mass of reactant is 4.002604 u
Mass of the products is
(2 because there are 2 of each)
The difference in mass is
So, the work done in MeV would be
The work done required to completely disassemble all the helium is 28.295244 MeV
Answer:
Higher frequency.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.
Mathematically, the speed of a sound is given by the formula:
Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.
A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.
Hence, shrill sound is of higher frequency.
