#1 A body has a mass of 6 kg on the Earth; when measured on the Moon, its mass would be
Mass of an object does not change when an objects location changes. It is the weight of the body (w = mg) which changes with value of ‘g’ at that place.
#2 When you pull out the plug connected to an electrical appliance, you often observe a spark. To which property of the appliance is this related?
Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. A common form of energy storage device is a parallel-plate capacitor.
#3 In step-down transformer, the AC output gives the
#4 A rectifier is an electronic device used to convert
A rectifier is used to convert AC voltage into DC voltage and invertor converts DC voltage into AC voltage.
#5 Magnetic, electrostatic and gravitational forces come under the category of
All of these forces doesn’t need any physical contact to exist hence, non-contact forces.
