Question

explain why is it difficult for a fireman to hold a hose, which ejects large amounts of water at a high velocity​

Answer 1

Explanation:

There are 206 bones in the adult human body and 300 in a child's developing body. Fleas can jump 130 times higher than their height. In human terms, that is equivalent to a 6-foot person jumping 780 feet into the air.

pls mark me as brainliest answer

Answer 2

Explanation:

The water that is ejected out from the hose in the forward direction comes out with a large momentum and equal amount of momentum is developed in the hose in the opposite direction and hence the hose is pushed backward. It becomes difficult for a fireman to hold a hose which experiences this large momentum.
