FALSE! You would still need to complete, just in case they accepted
Because it spin so slow over the course of a whole day.
Answer:
Acceleration of object=
Explanation:
Given:-
Velocity (v)=24 cm/s
Time (t)=3 s
To calculate acceleration (a) of object=?
Now,
Therefore object acceleration =
Mass defect is the difference of the mass of the constituent particles (protons and neutrons) of the actual mass of the nucleus. The mass of a nucleus is actually less than the mass of the protons and neutrons.
This is how you calculate it for this problem.
lithium - 7 => 3 protons and 4 neutrons
mass of 3 protons = 3 * 1.007276 amu = 3.021828 amu
mass of 4 neutrons = 4 * 1.008665 amu = 4.03466
=> mass of 3 protons + 4 neutrons = 3.021828 amu + 4.03466 amu = 7.056488
Mass defect = mass of 3 protons and 4 neutrons - atomic mass of lithium =
Mass defect = 7.056488 amu - 7.016003 amu = 0.040485 amu
