At constant temperature the volume of gas is 95cm3 at a pressure of 9.961×10^4 Newton per metre square. What would be its volume at 10.13×10^4 Newton per metre square?
Answers
Answer:
x ∝ t3
⇒ v = dx/dt
⇒ v ∝ 3t2
a = dv/dt
⇒ a ∝ 6t
a ∝ t
Acceleration is directly proportional to time elapsed. The body undergoes uniform acceleration. The graph of acceleration and time will be a straight line graph.

Volume of earth ==1.082 x 1021 m3
Density of earth = 5.975 x1024/1.082 x 1021 = 5.52 x 103 kg/m3
13. The heat dissipated in a resistance can be determined from the relation : H = I^2Rt/4.2 Cal.
If the maximum errors in measurement of current, resistance and time are 2%, 1% and 15% respectively what would be the maximum error in the dissipated heat ?
=20%
