The work is Work= FD= 40x18= 720 Joules. The power is W/seconds = 720/4= 180 Watts.
The amount of work done by each person can be calculated by analyzing the amount of energy they each use to climb the stairs. Energy is related to work (force multiplied by distance) and can be measured in joules. The person who climbs the stairs in 30 seconds will have used more energy (and thus done more work) than the person who climbs the stairs in 40 seconds. This is because the person who climbs in 30 seconds had to exert more force to climb the stairs faster thus expending more energy in a shorter amount of time.The following factors will determine how much work each person did: The weight of each person The amount of stairs climbed The rate of ascent (how fast they climbed the stairs) The amount of energy usedAlthough the two people weigh the same the person who climbed the stairs in 30 seconds used more energy than the person who climbed in 40 seconds. This is because the person who climbed in 30 seconds had to exert more force in order to ascend the stairs faster. This force requires more energy to be used and thus the person who climbed in 30 seconds did more work.

Yes
ocean currents, local geography,elevation,distance from large bodies of water and latitude
1,000 N apex=500 N

You would expend 2 watts of power when you exert a force of 1N that moves a book 2m in a time interval of 1s.
his force is clearly 200N
a. moving molecules that exert forces.
You would expend 2 watts of power when exerting a force of 1 N to move a book 2 meters in one second. This can be calculated using the formula for power, which is Power = Work / Time. Given that Work = Force x Distance, the power expended would be 1 N * 2 m / 1 s = 2 watts.
Power=120W=work/time=Force*distance/time. so' 120=F*15/5, or 120*5=F*15 , so, F=600/15=40N
Not that much actually.
The force that moving charged particles exert on one another is called the electromagnetic force. This force is responsible for the interaction between charged particles such as electrons and protons.
False. According to Bernoulli's principle, faster-moving fluids exert less pressure compared to slower-moving fluids. This is because faster-moving fluids have lower internal energy and therefore exert less pressure.
Weight. Also, the moving air around the plane causes friction
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
