What is a device that converts mechanical energy to DC electrical energy? In electricity generation, a generator is a device that converts mechanical energy to electrical energy for use in an external circuit. DC generator or direct current generator generates a voltage when speed and flux are met. This machine is called a unidirectional (dynamo). […]
Which even happens in a solar cell when the photoelectric effect occurs?
Which even happens in a solar cell when the photoelectric effect occurs? Answer. Answer: Light shone on metal expulses electrons from its surface. This phenomenon is the photoelectric effect, and the electrons are called photoelectrons. How can we apply photoelectric effect in daily life uses? The rest of the photon’s energy transfers to the free […]

Does hot rolling increase hardness?
Does hot rolling increase hardness? It had be concluded so far that in hot rolling, increase in height of roll grooves which was a function of its expansion, caused by the process parameters, resulted in increase in thickness of rolled stock, which affected the mechanical properties of the rolled samples such as ultimate tensile strength, […]
Which light has highest energy?
Which light has highest energy? violet Which Colour has most energy? Which Colour has high energy? Violet What happens if you put too much voltage through an LED? First off, an LED is a current driven device, not a voltage driven device. That is, it doesn’t really care what the voltage is, but it does […]
What is the difference between a wheel bearing and axle bearing?
What is the difference between a wheel bearing and axle bearing? The differences between front wheel bearings and axle bearings are significant. Wheel bearings are installed in pairs consisting of both inner and outer bearings, whereas axle bearings are installed as a single bearing and only support the outer end of the axle shaft. Are […]
How do the geosphere and hydrosphere work together?
How do the geosphere and hydrosphere work together? When a parcel of air in the atmosphere becomes saturated with water, precipitation, such as rain or snow, can fall to Earth’s surface. That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones. […]
How do you control soil temperature?
How do you control soil temperature? Controlling Soil Temperature Mulch. Mulch acts as an insulation. Compaction. Loose soil contains air spaces that insulate the soil, acting a little like a much. Moisture. Water in the soil conducts heat rapidly. Shade. Since the sun is the source of most soil heat, shading the soil keeps it […]
