Output can not be greater than input because the conversion of energy can not be greater than 100%.
Answer:
right
Explanation:
Current flows from the positive (+ve) terminal of the battery to the negative (-ve). This is called conventional current flow.
Therefore, the electrons are negatively charged and want to get away from the Negative Terminal and go to the Positive Terminal, Hence the electrons move from left to right and current flows from right to left.
Choice-'b' says the formula for kinetic energy in words.
KE = (1/2) · (M) · (S²)
Ice is only thing which is mightier than steel because it can breaks things which are made up of steels like ships but in the sunlight ice melts away it means it cowards away.
