We have the following values used to solve this:
For ⁴₂He:
No of protons: 2
No of neutrons : 2
Mass of proton: <span>1.00728 amu
Mass of neutron: </span><span>1.00867 amu
Atomic mass: </span><span>4.002603 amu
The formula to solve for the mass defect is:
md = (mp + mn) - mo
md = (2x</span>1.00728 + 2x1.00867) - 4.002603
md = 0.029297
Therefore, the mass defect is 0.029297 amu
Total distance covered is 47.1 m whereas displacement is zero.
<h3>Calculation:</h3>
Given,
Diameter, d = 5 m
No. of revolutions = 3
Radius, r = 5/2 = 2.5 m
To find,
Distance =?
Displacement =?
Distance covered in one revolution = 2πr
Put the values in this,
Distance = 2 × 3.14 × 2.5
= 15.7 m
Total distance covered in 3 revolution = 3 × 31.4
= 47.1 m
Displacement is the change in the position of the object or the distance between the initial and final position.
After 3 revolutions the particle comes back to its initial position. Therefore, the displacement is zero.
Hence, the total distance covered in 3 resolutions is 47.1 m whereas displacement is zero.
