How much work is required to lift a 10 Newton? In the diagram, 55 joules of work is needed to raise a 10-newton 5.0 meters. How much work is done on a 10 N block that is lifted 5 meters off the ground by a pulley? ⛬ w = 10 x 5 = 50 J […]
What is the weight of a glider with a mass of 5.3 grams?
What is laser and its principle?
What is laser and its principle? The principle of laser amplification is stimulated emission. If the gain is larger than the losses, the power of the light in the laser resonator rises very rapidly, starting e.g. with low levels of light from fluorescence. What is the full meaning of laser? light amplification by stimulated emission […]
What happens to the working distance as you increase magnification?
What happens to the working distance as you increase magnification? Working distance is how much space exists between the objective lens and the specimen on the slide. As you increase the magnification by changing to a higher power lens, the working distance decreases and you will see a much smaller slice of the specimen. What […]
What is meant by stress strain diagram?
What is meant by stress strain diagram? Stress strain curves visually display the material’s deformation in response to a tensile, compressive, or torsional load. Depending on the material being tested, a stress strain curve can indicate key properties of the material including its elastic region, plastic region, yield point, and ultimate tensile strength. What is […]
What are the factors influencing the ideal Brayton cycle efficiency?
What are the factors influencing the ideal Brayton cycle efficiency? Key factors affecting the Brayton cycle efficiency includes the turbine inlet temperature, compressor and turbine adiabatic efficiencies, recuperator effectiveness and cycle fractional pressure loss. Which gas turbine is used in aircraft? Turbofans What is meant by gas turbine? A gas turbine is a combustion engine […]
How do you calculate the amount of heat lost?
What is a screen scheme?
What is a screen scheme? A ‘screen scheme’ allows you to choose which screen will be shown to a Jira user when they perform a particular issue operation. There are three issue operations for which you can choose a screen: Create issue — the screen that is shown when an issue is being created. What […]
Can the COP of a refrigerator be greater than 1?
Can the COP of a refrigerator be greater than 1? COP of refriegeration is always greater than one. The coefficient of performance (COP) of refrigeration is always more than 1. COP is the ratio of heat extracted from the refrigerator to the work done on the refrigerant. It is also called by the name Theoretical […]

When tracing the power flow from the engine to the drive wheels what transmits power directly to the transmission input shaft? When tracing the power flow from the engine to the drive wheels, what transmits power directly to the transmission input shaft? When the clutch is released or the pedal is in the up position, […]
