A 10L helium balloon at a pressure of 2 bar at 27C. some O2 is now in balloon and final volume is made 30L. the pressure also fell to 1 bar at same temperature. the partial pressure of O2 at end is?
A 10 kilogram body initially moving with a velocity of 10 meters per second makes a head-on collision with a 15 kilogram body initially at rest. The two objects stick together

a lead bullet moves horizontally with a velocity of 130ms and embedded into a cement wall after collision. if the specific heat capacity of lead = 130J/KgC and all heat produces is
Advantages of D.C. transmission of power 1. It needs only two conductors as compared to three for a.c. transmission. 2. There is not an inductance, capacitance, phase displ
A long solenoid has a diameter of 10.4cm. When a current I exists in its windings, a uniform magnetic field of magnitude B=37.7 mT is produced in its interior. By decreasing I, the
What is the stimulated emission? Define this term briefly. Stimulated emission: a. While photon interacts along with atom that is in the excited state E 2 , in that case de-
When a body or a moving particle repeats its motion along an exact path after regular parts of time, its rotation is said to be Periodic Motion and interval of time is known as per
p1v1=p2v2 let partial pressure of helium in 30L be P then p1*30=2*10 p1=20/30 bar=2/3bar partial pressure of O2=p2 p1+p2=1bar partial pressure of O2=1/3 bar
p1v1=p2v2
let partial pressure of helium in 30L be P
then p1*30=2*10
p1=20/30 bar=2/3bar
partial pressure of O2=p2
p1+p2=1bar
partial pressure of O2=1/3 bar
