Answer:
The atoms of noble gases already have complete outer shells
Explanation:
so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions. ... atoms of group 0 elements have complete outer shells (so they are unreactive)
Their combined speed will be 1m/s
Given the following parameters;
- The velocity of the first hockey player is 1m/s.
- The velocity of the second hockey player is 2m/s.
If the player collides and stick together, the combined speed is expressed as;
- Combined speed = differences in velocity
- Combined speed = 2m/s - 1m/s
- Combined speed = 1m/s.
Hence their combined speed will be 1m/s

The amount of power required to move the 120 Kg person to a distance of 35 m in 150 s is 274.4 W
<h3>How to determin the power</h3>
Power is simply defined as the rate at which work is done. It can be expressed mathematically as
Power (P) = work (W) / time (t)
But
Work = force (F) × distance (d)
Therefore,
P = Fd / t
With the above formula, we can obtain the power as follow:
- Mass (m) = 120 Kg
- Distance (d) = 35 m
- Time (t) = 150 s
- Acceleration due to gravity (g) = 9.8 m/s²
- Force (F) = mg = 120 × 9.8 = 1176 N
- Power (P) = ?
P = Fd / t
P = (1176 × 35) / 150
P = 41160 / 150
P = 274.4 W
Thus, the power is 274.4 W
