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%
