When electric heater is switched on, it is noticed that the lamps in the room become dimmer for a short interval of time and then regain their original brightness. Explain.​

Answers 2

Answer:

After some time, when heater coil becomes hot its resistance increases. As a result, current through the heater coil decreases and the current through the bulb filament increases and thus dimness of the bulb decreases.

difference between linear velocity and angular velocity​

Angular velocity is defined as the rate of change of the angular position of a rotating body. Linear velocity is defined as the rate of change of displacement with respect to time when the object moves along a straight path.

In linear velocity,

=> the motion occurs in a linear, straight line(not necessarily axially)

=> the direction of motion is in one direction.

In angular velocity,

=> the motion occurs in a circular path

=> the direction of motion keeps changing w.r.t. time.

Anabolic Process,catabolic process​

Answer:

Catabolism, at its core, involves breaking down of complex molecules and releasing energy for the body to use. The anabolic process is the complete opposite of catabolism as it involves creating bigger, complex molecules from smaller, simpler molecules. These are usually stored by the body for future use.

Explanation:

THANKS..

Answer:

Anabolism is a biochemical process in metabolism where the simple molecules combine to generate complex molecules. This process is endergonic, which means it is not spontaneous and requires energy to progress the anabolic reaction.

The Catabolism process is the action of the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions.
