A machine has an efficiency of 91 percent If the energy supplied to the machine is 4000 watts what is the amount being used for work?
4,091 watts
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
Which type of machine machine changes the direction or amount of force needed to do work?
Simple
What does not reduce the amount of work that has to be done?
A force machine does not reduce the amount of work that has to be done
Does the machine decrease the amount of work to be done?
yes
A machine has an efficiency of 91 percent If the energy supplied to the machine is 4000 watts what is the amount being used for work?
4,091 watts
A machine has an efficiency of 91 percent If the energy supplied to the machine is watts what is the amount being used for work?
If the efficiency is 91%, then work = 0.91 times watts
Is Joule the metric unit of work power force or effciency?
it is the amount of power
What amount of the Body's energy is supplied by fat?
Fat supplies 60 percent of the body's energy
A machine has an efficiency of 91 percent if the enery supplied to the machine is 4000 watts what is the amount being used for work?
Turn the percentage into a decimal by dividing by 100: 91% --> .91Work out = (efficiency) * (work in)dividing by a unit of time gives =>Power out = (efficiency) * (power in)P_o = .91 * 4000 Watts = 3640 Watts
If the energy supplied to the machine is 4000 watts for 91 percent efficiency what is the amount being used for work?
The idea here is to calculate 91% of 4000. By the way, technically "watts" is not a unit of energy. It is a unit of power - that is, energy per unit time.
What amount of voltage is supplied by an ordinary cell?
What amount of voltage is supplied by an ordinry cell?
A motor with an efficiency of 75 percent must supply 240 J of useful work. What amount of work must be supplied to the motor?
At least 320 J
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
The amount provided at one price?
quantity supplied
Amount provided at one price?
Quantity supplied
Why is the amount of that a machine does is less than the amount put into the machine?
In such a machine, the remaining energy is wasted to friction
