When a spoon is in a glass half full of water Why does the spoon look like it is broken in the middle? It is refraction due to which we saw spoon broken near water surface. 1. If you put a coin inside glass of water and view it from the top then coin appears […]

Is it cheaper to leave AC on all day? In general, it is cheaper to leave the AC on all day during very hot temperatures. However, turning off the AC during a heat wave can quickly introduce a lot of heat and humidity into your home. After even just a couple of hours, your AC […]

What is the speed of light in a medium of refractive index n? The refractive index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength […]

Does more water make plants grow faster? Water helps a plant by transporting important nutrients through the plant. With outdoor plants, you can’t control the plants getting too much water if your area gets a lot of rain, so you need to make sure that the soil has the proper drainage, because too much water […]

Which rule of Fleming can be used to determine the direction of induced 1 current in the secondary coil if current in the primary coil is changed? Fleming’s Right hand rule – If the forefinger, second (central) finger and thumb of the right hand are stretched at right angles to each other, with the forefinger […]

What happens when a gas expands at constant temperature? Therefore, at a constant temperature, the kinetic energy will also be the same. Therefore, when gas expands at a constant temperature, pressure decreases as well as kinetic energy of the molecules will remain the same. What happens to pressure when gas expands? When the gas expands […]

At which stage is potential energy at its minimum? The potential energy due to gravity is at a minimum, since the mass is lifted the least amount above ground. In fact, if ground level is imagined at the bottom of the motion, the potential energy due to gravity is zero at this point of the […]
