A Balloon is inflated with Air by connecting it to a well insulated 100 L gas canister. Initially the air canister is at a pressure of PC1 = 9 MPa and at a temperature of TC1 = 25ºC. The pressure, PB, [kPa] in the balloon is proportional to its volume, VB [m3], by the following relationship: PB = 100 + 20 VB= . The balloon is inflated until its volume is 0.5434 m3. The balloon exchanges heat with its surroundings and maintains the same a temperature of 25ºC. Determine the following by assuming all processes to be reversible and the air to be ideal.
a) The mass of air that entered the balloon
b) Final temperature and pressure in the canister
c) The amount of heat transferred between the balloon to the surroundings.
With the help of a ray diagram, explain the formation of the final image of an object in a compound microscope. Derive a mathematical expression for its magnifying power.
Defect: The image is formed behind the retina and lens becomes converging.
Derive the equation of uniformly acceleration motion by analytical method.
what is the physical significance of damping coefficient?
Illustrate Bio-Savart law. Describe instantaneous, rms, and maximum values of a current.
Are fibers safe? Fiber optics are passive components, hence do not use power to generate light, like the case with lamps. When light conductors only carry light from one point
In the experiment, under which of the following circumstances is the angular momentum L of the movable puck NOT conserved? a) The net torque = 0. b) The radius r is always perpen
Give reasons for the following (i) Long distance radio broadcasts use short-wave bands. (ii) The small ozone layer on top of the stratosphere is crucial for human survival.
