Answer:
Mass
Explanation:
The total sum of atoms in an object is the mass of the object. There are several ways to quantify the number of atoms in a substance.
- In chemical calculations, the number of moles is a good representation of the number of atoms contained in a body.
- Mass is the amount of substances a body has.
- If we can sum up all the atoms in a substance, one will arrive at the mass of the substance
Bob gained (80lbs x 14ft) = 1120 ft-lbs of energy.
Fred gained (110lbs x 14ft) = 1540 ft-lbs of energy
Since they both took the same amount of time, Fred's power (rate
of doing work) was greater than Bob's power (rate of doing work).
Wavelength = speed / frequency
= (350 m/s) / (440/s)
=. 0.795 meter
