The main difference between protium, deuterium, and tritium is that protium has no neutrons in its nuclei, whereas deuterium is composed of one neutron and tritium is composed of two neutrons [17]. Protium is an isotope of hydrogen that is composed of one proton and one electron.
Power is the rate of doing work or using energy.
The unit of power is the watt.
1 watt = 1 joule per second
Answer:
Displacement = 
Magnitude of displacement = 13.89 units
Angle of displacement = 30.26°
Explanation:
Mark the co-ordinates of each of the end points of the vectors.
The marked co-ordinates are shown below.
Displacement is the shortest distance between two points. Here, displacement between the starting and end points is the vector 
.
Displacement vector for a point A
from origin O is given as:
Magnitude is given as:
Direction of the vector is given as:
Therefore, displacement vector is:
Magnitude of displacement is given as:
Angle of displacement is:
°
Momentum = mass x velocity
Before collision
Momentum 1 = 2 kg x 20 m /s = 40 kg x m/s
Momentum 2 = 3 kg x -10m/s = -30 kg x m/s
After collision
Momentum 1 = 2 kg x -5 m/s = -10 m/s
Momentum 2 = 3 kg x V2 = 3V2
Total momentum before = total momentum after
40 + -30 = -10 + 3V2
V2 = <span>6.67 m/s
Total kinetic energy before
</span><span>= (1/2) [ 2 kg * 20 m/s * 2 + 3 kg * ( -10 m/s) *2 ]
= 550 J
</span>
<span>Total kinetic energy after
</span>= (1/2) [ 2 kg * ( - 5 m/s) * 2 + 3 kg * 6.67 m/s *2 ]
= 91.73 J
Total kinetic energy lost during collision
=<span>550 J - 91.73 J
= 458.27 J</span>
