What else can I help you with?
If the work put into a lever is 930 joules and the work accomplished is 870 joules the efficiency of the lever is?
The efficiency of the lever can be calculated as the ratio of the output work to the input work, multiplied by 100% to express it as a percentage. In this case, the efficiency would be 870 joules (output work) divided by 930 joules (input work), multiplied by 100% which equals 93.55%.
Is energy input is greater than enrergy out put?
In machines, this is always the case, since the machine won't work at 100% efficiency.
Is pencil case a compound word?
is it compound

What is the lever for in the trunk of a Fleetwood Cadillac?

When is the risk of infection greater after fracture repair?
Infection can interfere with bone repair. This risk is greater in the case of a compound fracture (a bone fracture causing an open wound) where ideal conditions are present for severe streptococcal and staphylococcal infections
What compound has a greater difference in electronegativities of its members NaCl or KCl?
The greater the difference in electronegativities between the elements in a compound, the stronger the bond will be. In this case, NaCl has a greater difference in electronegativities between sodium (Na) and chlorine (Cl) compared to KCl, since chlorine is more electronegative than sodium. This makes the ionic bond in NaCl stronger than that in KCl.
What do you use oil for?
energy in the case of fuels; and an increaser of efficiency in the case of a lubricant.
What type of lever is the axe?
An axe is a type of lever known as a class 1 lever. In a class 1 lever, the fulcrum is located between the effort (in this case, your hand on the handle) and the load (the wood being chopped).
If A lever is used to lift a heavy rock the mechanical advantage of the lever is 4 and the lever applies a force of 800n to the rock what is the force applied to the lever?
The force applied to the lever can be found by dividing the force exerted on the rock by the mechanical advantage of the lever. In this case, the force applied to the lever would be 200 N (800 N / 4).
How do you change into or out of 4 wheel drive in a 98 Toyota 4Runner?
Press the button on the left side of the transfer case selector lever. It's the lever on the console next to the gear shift lever.
How are hole punchers a second class lever?
Hole punchers are a second-class lever because the input force is applied at one end (effort) to overcome a resistance located between the input force and the fulcrum. In this case, the resistance is the paper being punched, and the fulcrum is where the punch contacts the surface. The force applied to the lever arm creates a torque that is greater than the resistance torque, allowing the hole to be punched.
