Intra aortic balloon pump is inflated by

Prosthesis that is designed to generate repetitive electrical impulses to the heart, is known as (a) Artificial cardiac pacemaker (b) Artificial heart valve (c) Intra-aortic balloon pump (d) Heart- lung machine

Suppose that a spherical balloon is inflated and it has volume 'v' and radius 'r' at time 't'. If the balloon is inflated by pumping 900c.c. of gas per second. Find the rate at which the radius of the balloon is increasing when the radious is 15 cm.

The radius of a spherical balloon increases from 6 cm to 10 cm when more air is pumped into it. The ratio in the surface area of the original balloon and the inflated balloon is:

eExplain why, when air is filled into a balloon, the balloon gets inflated.

When a balloon is inflated both its volume and its pressure increase.Is there any violation of Boyle's law?

A balloon which always remains spherical on inflation is being inflated by pumping in 900 cubic centimeters of gas per second. Find the rate at which the radius of balloon increases when the radius in 15 cm.

A balloon which always remains spherical is being inflated by pumping in 10 cubic centrimeters of gas per second . Find the rate at which the radius 15 cm .

A balloon which always remains spherical is being inflated by pumping in 10 cubic centimeters of gas per second. Find the rate at which the radius of the balloon is increasing when the radius is 15cm.
