so one liter is about 2. something gallons so at 12.8 km/l you would get about 30 mpg which is insane but yeah
Answer:
The correct answer is V1/T1=V2/T2.
Explanation:
Just took the test
The efficiency of any machine is given by:
efficiency = output obtained / input given
Substituting the values,
Efficiency = 105 / 150
Efficiency = 0.7
Converting this to a percentage, the efficiency of the hammer is 70%.
This is a fairly high efficiency, and this is due to the fact that the hammer is a simpler machine. The more complex a machine is, the greater are the losses in it due to friction, meaning there is a lower efficiency.
