A water fountain on the ground sprinkles water all around it . If the speed of water coming out of the fountain is ` v` , the total area around the fountain that gets wet is :

A

`pi/2 v^(4)/g^(2)`

B

`pi v^(2)/g^(2)`

C

`pi v^(2)/g`

D

`pi v^(4)/g^(2)`

Text Solution

Verified by Experts

The correct Answer is:
4

`R_("max")=u^(2)/g`, Area `=pir^(2)=(piu^(2)R_("max")^(2))/g^(2)`

A cylindrical vessel of height 500mm has an orifice (small hole) at its bottom. The orifice is initially closed and water is filled in it up to height H. Now the top is completely sealed with a cap and the orifice at the bottom is opened. Some water comes out from the orifice and the water level in the vessel becomes steady with height of water column being 200mm. Find the fall in height(in mm) of water level due to opening of the orifice. [Take atmospheric pressure =1.0xx10^5N//m^2 , density of water=1000kg//m^3 and g=10m//s^2 . Neglect any effect of surface tension.]

A strange cat with a mass m_(c ) is sitting at rest on the left sled of a pair of identical sleds. The sleds hace mass m_(s) and sit on frictionless ice. Suddenly, the cat leaps to the right sled, traveling with a horizontal speed v_(cg) measured with respect ot the groun. The instant the cat reaches the right sled, it turns around and leaps back to the left sled. The horizontal component of the cat's speed is again v_(cg) measured with respect to the ground. The final speed of right sled in terms of the masses of the cat and sleds and the cat's leaping speed is (The cat remains on the left sled after its return) :-
