What is an example of friction reducing the efficiency of a machine?
An example of friction reducing the efficiency of a machine is when two moving parts rub against each other, causing heat and wear. This can lead to energy loss and increased maintenance needs, decreasing the overall efficiency of the machine.
What do wheels and gears of a machine are greased in order to decrease I know the choices are potential energy efficiency output and friction?
Wheels and gears of a machine are greased in order to decrease friction. This helps to reduce wear and tear on the components, improve energy efficiency, and increase the overall output of the machine. Greasing helps to create a smooth surface between moving parts, allowing them to operate more efficiently.
What factor prevents a machine from operating at 100 percent efficiency?
Friction is one factor that prevents a machine from operating at 100 percent efficiency. Some energy is lost as heat due to friction between moving parts, which reduces the overall efficiency of the machine.
How is a real machine and an ideal machine different?
A real machine is a physical device with moving parts that may have friction and energy losses, resulting in reduced efficiency. An ideal machine is a theoretical concept that assumes no energy losses due to friction or other factors, resulting in 100% efficiency. Ideal machines are used for theoretical calculations and comparisons, while real machines consider practical limitations and inefficiencies.
How does a lubricant affect the efficiency and the frictional force of a machine?
A lubricant reduces friction between moving parts by forming a protective film, which decreases wear and tear on the machine parts. This improves efficiency by reducing energy losses due to friction and heat generation. Additionally, the lubricant helps to dissipate heat away from the machine components, further enhancing efficiency and minimizing the risk of overheating.
How do washer magnets contribute to the efficiency of a washing machine?
Washer magnets help to improve the efficiency of a washing machine by reducing friction and wear on moving parts, which can help the machine run smoother and last longer.

how do insects increase the efficiency of gas exchange during strenuous activity?
No
How can you increase purchase efficiency?
You can increase your purchase efficiency by reducing the amount of dead stock or slow moving inventory items. This will lower your total inventory value, increasing purchase efficiency. "Stock Items Only Of Which You Have Need"

Why Are There no machines that that use energy with 100 efficiency?
From a practical standpoint there are no machines that use energy with 100% efficiency because all movement generates some friction and hence heat and loss of efficiency. Even electrons moving through superconductors generate minute amounts of heat. From a theoretical standpoint it's impossible to get 100% efficiency; all energy transformations increase entropy. Even if you could devise a machine with no friction, the process of converting energy from one form to another ALWAYS increases entropy. It's a result of the second law of thermodynamics. No machine can perform with 100% thermodynamic efficiency. The process used by any machine, be it steam, electric, horse drawn, wind, or whatever, can be reduced to a simple description of heat moving from a higher temperature to a lower temperature. The Carnot cycle provides a means to calculate the maximum theoretical efficiency possible. In reality, this maximum efficiency is NEVER achieved due to heat losses, friction, etc. Note that according to the Carnot cycle, 100% efficiency is impossible. The energy input to the machine can NEVER be entirely converted to useful work. Some of the energy is ALWAYS lost as heat to the surroundings.
If an object accelerates in the same direction in which it is moving how is its speed affected?
If an object accelerates in the same direction in which it is moving, its speed will increase. This is because the acceleration is adding to the object's existing velocity in the same direction, causing it to move faster over time.
Cloud the pendulum be changed to increase the period of the pendulum?
Yes. You can increase the period by moving the pendulum to a location where the gravitational force is weaker.Alternatively, you can increase the effective length of the pendulum. The pendulum may be of fixed length, but you can still increase its effective length by adding mass to any point below its centre of gravity.Yes.

Why is lubricating oil put on moving parts of a machine?
Lubricating oil is applied to moving parts of a machine to reduce friction, which helps prevent wear and tear on the components. It also helps dissipate heat, improve efficiency, and extend the lifespan of the machine by reducing mechanical stress.
