As the time required to run up the stairs increases, the power developed by that person
Increases, decreases, or remains the same.
Is the answer decreases?
To determine how the power developed by a person changes as the time required to run up the stairs increases, we need to consider the relationship between power, work, and time.
Power is defined as the rate at which work is done or energy is transferred. Mathematically, power (P) is given by the equation:
P = W/t
Where P is the power, W is the work done, and t is the time taken. In this case, the work being done is running up the stairs.
Now, if the time taken to run up the stairs is increasing while the work being done remains constant, it means that the rate at which the work is being done is decreasing. Since power is directly related to the rate at which work is done, if the rate decreases, the power will also decrease.
Therefore, the answer is correct. As the time required to run up the stairs increases, the power developed by that person decreases.
No, the correct answer is increases. As the time required to run up the stairs decreases, the power developed by that person increases. Power is defined as the rate at which work is done or energy is transferred, and it is calculated by dividing work or energy by time. When someone runs up the stairs in less time, they are doing the same amount of work (applying the same force over the same distance) but in less time, which results in a higher power output.
yes the answer is decreases because
the work done by the same person going up the stairs whether he or she is running, walking or crawling remains constant, therefore if the time going up the stairs is increased, then the power is decreased.
