Comments (10) on “Which two factors does the power of a machine depend on”
C. Work and time
Explanation:
Power is the rate work is done, so this would involve how long it would take to do a certain amount of Work and it is also the measure of the transfer of energy over a period of time.
The work of an object is the transfer of energy that occurs when a force makes an object move, for work to be done, something has to move and the motion must be the same direction as the force. Work(joules)= Force(Newtons)*Distance(Meters). Power is the rate at which work is done. The formula for power is: Power(Watts)=Work(J) / time(in seconds). Knowing all this, we can safely assume that the power of a machine depends upon work and time.
The power of a machine depend on two factors are work and time.
Option C
Explanation:
In science, power defined as the amount of work done in a unit time. i.e. delivering work in a rate of time or energy supply, expressed in input of work or transmitted energy divided by the time interval (t) or W/t.
Example: Some work can be done in the long run with a low-power engine or in a short time with a motor with high performance. The equation for power can be given as
[tex]Power\ (in\ watts) =\frac{\text { work (joules) }}{\text { time (seconds) }}[/tex]
C. Work and time
Explanation:
Power is the rate work is done, so this would involve how long it would take to do a certain amount of Work and it is also the measure of the transfer of energy over a period of time.
The formula for power is:
[tex]P = \dfrac{W}{t}[/tex]
Where:
P = Power
W = Work
t = time
c. work and time
Explanation:
c is right on plato
Number of ions and Permeability
It is work and time C. is the answer. I hope i could help.
THE ANSWER IS C
C
Explanation:
The work of an object is the transfer of energy that occurs when a force makes an object move, for work to be done, something has to move and the motion must be the same direction as the force. Work(joules)= Force(Newtons)*Distance(Meters). Power is the rate at which work is done. The formula for power is: Power(Watts)=Work(J) / time(in seconds). Knowing all this, we can safely assume that the power of a machine depends upon work and time.
c
Explanation:
Work and time
Explanation:
(1) Power of a machine is given by :
[tex]P=\dfrac{work\ done}{time\ taken}[/tex]
The work done of a machine is directly proportional to the work done and inversely proportional to the time taken by it.
So, the power of a machine depend on the work done and time taken. The correct option is (c) "work and time".
(2) This part is same as part 1.
i.e. power = work done/ time
or P = W / t
Hence, the correct option is (c) " work and time ".
The definition of mechanical power is
Power = (work done) / (time to do the work).
From that definition, it looks pretty much like the power of a machine
depends on work and time.
The power of a machine depend on two factors are work and time.
