In order to be electrically neutral, an atom has to contain
equal numbers of protons (with their positive charges) and
electrons (with their negative charges).
Answer:
<em>12.5watts</em>
Explanation:
Power = Workdone/Time
Since workdone = Force * Distance
Power = Force *distance/Time
Given
Force = 150N
Distance = 10m
Time = 2 minutes = 120seconds
Required
Power
Substitute the given values into the formula;
Power = 150 * 10/120
Power = 1500/120
Power = 12.5Watts
Hence his power is 12.5watts
<em></em>
A. direction
The two factors that relative speed overall depends on are individual speed and direction.
a)5m/s b)5
the 5 is because you add the seconds to get 8 seconds and then do the same with the distance to get 40. 40/8 = 5. speed = 5
Velocity = displacement/change in time
V = 40/8
I just realized how unorganised my math looks but I hope this is helpfull
Answer:
27 °C
Explanation:
BY the statement of the question it is clear that it is about an ideal gas - and hence if change in KE is about zero - then there will be no change of temperature.
So, answer is 27 °C
