Answer:
final volume the balloon occupy in instant before it burst is 4.634 L
Explanation:
given data
helium filled V1 = 2 L
initially pressure P1 = 1.25 atm
finally pressure P2 = 410 mmHg
1 atm = 760 mmHg
to find out
at what volume the balloon occupy in instant before it burst
solution
we have given
760 mmHg = 1atm
and 1 mmHg = 1/760
so 410mmHg = 410/760 atm
so that final pressure is = 410/760 atm
we use here Boyle's Law that is
Boyle's law states that "the volume of an ideal gas is inversely proportional to the pressure of the gas at constant temperatures"
so P ∝ 1/V
P1V1 = P2V2
V2 = P1V1 / P2
put all value
V2 = 1.25 (2) / (410/760)
V2 = 2.5 / 0.53947 = 4.634
so final volume the balloon occupy in instant before it burst is 4.634 L

Answer:
Explanation:
Power Dissipated in a resistor is given by two methods i.e.
and
where 
both formula gives Power but Former is used when voltage is constant i.e. when resistors are in parallel and the later is used when the resistor are in series .
Though can also be used in series but we have to calculate the Potential drop across each resistor then we can apply the formula.
Similar is with 
First we have to calculate current through each resistor then we can apply the Formula
