Need a hypothesis for how does your power in climbing a flight of stairs compare with the power of a 100 W light bulb?
A hypothesis could be that your power is the same. Or it could be that your power is a million times greater or only one millionth. You decide!A hypothesis could be that your power is the same.

What is the power if 35N force 5 Meters and takes 19 seconds to push?
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
How many ms are in 6.7 seconds?
6.7 times 10 to the -3 power
During a winter storm an entire town lost power for 2.6 hours How many seconds is this?
2.6 hours = 2.6*60 minutes = 156 minutes = 156*60 seconds = 9360 seconds.
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
Dan climbs a flight of stairs in 0.025 s. If he weighs 550 N and the stairs is 10 m from the ground, how much power in watts will he developGIVEN:UNKNOWNEQUATION: SOLUTION?
a lot
What is the average power supplied by a 60.0 kg secretary running up a flight of stairs rising vertically 4.0m in 4.2 seconds?
NO ANSWER?!....This is unacceptable in this organization. -.-
A 50 kilogram person climbs a 15 meter high flight of stairs in 30 seconds How much power did their body produce during their climb?
25 watts NOOOOOOOOOOOO! you are sooo wrong,. i hate to correct you but it bloody 250 okay so when you give an answer MAKE SURE ITS FRIKEN WRITE NEXT TIME BLACKMAN!
If A 100 kilogram man climbs a flight of stairs to a height of fourteen meter in ten seconds how much is the power and for the work done?
To raise 100 KG by 14 meters the work done is 100 x 9.81 x 14 = 13734 Joules. (9.81m/sec2 is the acceleration of a body in free fall, commonly called 'g') To do this work in 10 seconds means a power of 1373.4 Joules/second = 1373.4 watts
How could you increase power if you walked up the stairs in ten seconds?
You can increase power by walking up the stairs in LESS time.
Frank does 2400J of work in climbing a set of stairs if he does the work in 6 seconds what is his power output?
400
Is there some limit to the height of the flight of stairs used and the horsepower developed?
There's no limit to the height of the stairs, but because power is the rate of doing work, different people would run up several flights of stairs at different rates, since each person has a "limit" on the amount of power she/she can produce.
What happens to the amount of power expended when you are climbing stairs and then climb faster?
I believe that the amount of power/energy you exert on yourself climbing up the stairs is wasted, and the faster you go, the faster the power is used up. It takes a lot of energy to go up one flight of stairs than it does going down five or so, depending on the body type of the person and maybe even the amount of gravity in that specific area.
Will you have the same power if you run up the same stairs?
It takes more power to run up the same stairs faster.
How does your power in climbing a flight of stairs compare with the power of a 100 W light bulb?
One joule is the amount of energy required to apply a force of one newton through a distance of one meter (one newton-meter), or it is the amount of energy required to produce one watt of power for one second (one watt-second).If we assume that you have a mass of 200 pounds or 91 kilograms, then it requires a force of 891 newtons (91 * 9.82) to support you. This force will be the same whether you are standing still or climbing, even though it will momentarily change when you accelerate, so we can use 891 newtons.If we then assume that a flight of stairs is about 3 meters, we can calculate the power to climb up at 891 * 3 = 2672 joules per flight.Lets look at the light bulb. That one is easy. 100 watts is 100 joules per second.Now the question is, how fast can you climb? Let assume 10 seconds per flight of stairs. That translates to 267 joules per second, so you use nearly three times the energy of a 100 watt light bulb to climb stairs. (Two times, if you climb a little bit slower.)
What is the name of power-driven set of stairs?
Escalator
If you exert a force of 700 N to walk 6 m up a flight of stairs in 6 s how much power do you use?
Calculate the energy required to raise the person (weight x height). Then divide that energy by the time, to get power.
