What else can I help you with?
The efficiency of a machine is always less than 100 percent because?
some energy is always lost to factors like friction, heat, and sound during the operation of a machine, reducing its efficiency below 100%.
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.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
Why is a machine always less than 100 percent efficient?
Machines are never 100% efficient due to factors such as friction, heat loss, and mechanical limitations. Some amount of energy will always be lost during the transfer or transformation process, making it impossible for a machine to achieve perfect efficiency.
What are factors that limit the efficiency of a machine?
Friction is the most common factor affecting the efficiency of any machine.
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
How does effieciency of the machine affects it's performance?
if a machine is not efficient, it cannot fully utilise its performance. actual performance = efficiency x possible performance efficiency = actual performance / possible performance efficiency is always a decimal number less than 1, as no machine is perfect in terms of efficiency

Can a machine's efficiency can be greater than 100 percent?
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
The efficiency of an ideal machine is 100 percent. Do any machines used in your daily life in ideal Give reason to support your answer?
No physical machine is ideal. Friction is always a loss of energy.
What is the rfficiency of a machine always less than 100 percent?
The efficiency of a machine is always less than 100 percent due to energy losses that occur during operation, such as friction, heat dissipation, and sound. These losses prevent all input energy from being converted into useful work. Additionally, the second law of thermodynamics implies that some energy will always be lost to entropy, making perfect efficiency unattainable in practical systems.
Why can efficiency never can be 100 percent?
The laws of thermodynamics imply that there will always be some loss of efficiency.
Why is a machine always less than 100 percent efficient?
Machines are never 100% efficient due to factors such as friction, heat loss, and mechanical limitations. Some amount of energy will always be lost during the transfer or transformation process, making it impossible for a machine to achieve perfect 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.
