What would cause the calorimeter efficiency to be less than 100 percent?
why is the efficiency of a calorimeter less than 100%
Is it possible for a first or second class lever to have a mechanical advantage less than one or for a third class lever to have a mechanical advantage greater than one?
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.
Why is it that efficiency of a machine is less than 1?
The efficiency is always less than one because some of the energy is always useless for what you want. Most wasted energy eventually turns into heat. therefore the efficiency is like a percentage with 1 being 100% a device can't be 100% efficient as some energy is wasted. To work out the efficiency of a device you need to do the total useful energy produced divided by the total energy that is inputted into the device
What is 10 percent less than 2500?
To find 10 percent less than 2500, you first calculate 10 percent of 2500 by multiplying 2500 by 0.10, which equals 250. Then, subtract 250 from 2500 to find the result. Therefore, 10 percent less than 2500 is 2250.
A percent change describing a decrease in a quantity?
Any percent less than 100.
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.
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.
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%.
What would cause the calorimeter efficiency to be less than 100 percent?
why is the efficiency of a calorimeter less than 100%
The efficiency of an actual machine is always less than what percent?
It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!
What is the mechanical efficiency of a inclined plane?
The mechanical efficiency of an inclined plane is the ratio of the output force to the input force, taking into account friction and other factors that may reduce efficiency. It is calculated as the ratio of the ideal mechanical advantage to the actual mechanical advantage. A perfectly efficient inclined plane would have a mechanical efficiency of 100%, but in reality, efficiency will be less than 100% due to energy losses.
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.
What can be done to increase the efficiency of the machine?
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
The mechanical advantage of a machine is always greater than 1?
well the advantage of that is pie, not math pie but pie that you eat
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
Levers have a greater mechanical efficiency that other simple machines because?
They have to overcome less friction
Why can't mechanical efficiency be over 100 percent?
The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient. As well.... Efficiency is (power out/power in) x 100. To get an efficiency of *more* than 100%, the machine must give more power out than is put in. No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.
