The safety fuse wire used in household electrical appliances is made of a metal with a low melting point. This characteristic allows the fuse to melt quickly and break the circuit when excessive current flows, thereby protecting the appliances and ...
The current flowing through a conductor connected to a 110-volt source can be calculated using Ohm’s law. Ohm’s law states that current (I) equals voltage (V) divided by resistance (R). Here, with a resistance of 440 ohms and a voltage ...
The mirror used for shaving is a plane mirror. It provides a non-inverted virtual image that appears to be the same size as the object, making it suitable for tasks requiring accurate reflection without distortion.
A convex mirror is preferred to see the traffic behind while driving. It provides a wider field of view, reducing blind spots and allowing the driver to monitor surrounding traffic effectively without significant distortion.
The image formed on the retina of the human eye is a real and inverted image. Light rays entering the eye converge onto the retina, where they form a small, inverted image of the visual scene, triggering neural signals that ...
The minimum height of a plane mirror to see the full image of a person should be equal to half the height of the person. Placing the mirror at this height ensures that the entire body from head to toe ...
During summer days, water kept in an earthen vessel stays cool due to evaporation. The porous nature of the earthen material allows water to seep through and evaporate from its surface, drawing heat energy from the surrounding water and keeping ...
Any boat will sink if it displaces water equal to its weight. According to Archimedes’ principle, the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. Therefore, ...
The reason for a piece of iron not floating on the surface of water is that the weight of water displaced by iron is less than the weight of iron. According to Archimedes’ principle, for an object to float, the ...
