Can you achieve 100 percent efficency with a lever and fulcrum?
Not if you consider the energy expended to grip or engage the lever--this does account for a minimum amount of lost efficiency
Can a simple machine efficiency ever be greater than 100 percent?
No, due to the fact machines loose energy due to heat/thermal energy. you will always loose some amount of energy.
What do all machines have that is less than 100 percent?
Perpetual motion. This answer is more related to the question "What do all machines DO NOT HAVE.
What percent is 47 percent out of 100 percent?
47 percent out of 100 percent is 47 percent (0.47 x 100 percent = 47 percent). More clearly, 47 % / 100 % = 47 / 100 = 0.47
What is 3 percent out of 100 percent?
3 percent out of 100 percent = 0.03 x 100 percent = 3 percent
Why are no machines 100 percent efficient?
Some energy is lost to friction.

How would you show how to measure the percent efficiency of an amp?
The Percentage Efficency for an amp is calculated via the following formula,Percentage efficency = (0.5÷amperage)×100= (0.5÷1)×100= ± 10%
What force stops machines from being 100 percent efficient?
One major factor that limits the efficiency of machines is friction. Friction creates resistance as moving parts come into contact with each other, leading to energy losses in the form of heat. Additionally, other factors such as air resistance, electrical resistance, and imperfections in materials can also contribute to reducing the overall efficiency of machines.

No, due to the fact machines loose energy due to heat/thermal energy. you will always loose some amount of energy.
Explain why machines are not 100 percent efficient?
because they are not proper
What is the force that prevents all machines from being 100 percent efficient?
One reason for this is friction, which results in energy loss due to heat production. Additionally, there are inefficiencies in the conversion of energy from one form to another, such as from mechanical to electrical energy. Finally, external factors like air resistance can also contribute to reducing the overall efficiency of machines.
Does an ideal machine have an effciency of 100 percent?
No, an ideal machine cannot have an efficiency of 100 percent. This is because some energy is always lost as heat due to factors like friction and resistance. The best an ideal machine can achieve is an efficiency of 100% by having no energy losses.
What do all machines have that is less than 100 percent?
Perpetual motion. This answer is more related to the question "What do all machines DO NOT HAVE.
Why aren't machines 100 percent efficient?
becaus ethey have friction
What causes the efficency of a machine to be less than 100 percent?
That means that some energy is wasted. For example, it is quite common for part of the input energy to be converted into useless heat.A drastic example is a traditional incandescent light bulb. Something like 5% of the energy gets converted into visible light. The remainder is radiated mainly as infrared - that is, heat radiation.
The efficiency of an actual machine is always less than what percent?
The efficiency of an actual machine is always less than 100 percent, as no machine can convert all input energy into useful output energy due to factors like friction, heat loss, and inefficiencies in the system.
