The equation PaVbTc= constant reduces to Charles Law if
a=1, b=1and c=0
a=1, b=0 and c=-1
a=0, b=1 and c=1
a=0, b=1 and c=-1
Correct answer is D
if a=0, b=1 and c=-1 then
P0V1T-1 = V/T (Charles Law)

Correct answer is B
VR = 800/200 = 4
\(Efficiency = \frac{MA}{VR} \times \frac{100}{1}\)
\(Efficiency = \frac{L}{E} \times \frac{1}{VR} \times \frac{100}{1}\)
\(Efficiency = \frac{800}{250} \times \frac{1}{4} \times \frac{100}{1}\)
= 78.74%

343.32N
233.33N
333.33N
334.33N
Correct answer is C
\(\frac{MA}{VR}\times\frac{100}{1}=efficiency\)
\(\frac{L}{E}\frac{1}{VR}\times\frac{100}{1}=75\)
\(\frac{1000}{E}\frac{1}{4}\times\frac{100}{1}=75\)
\(E = \frac{250 \times 100}{75}\)
E = 333.3N
