Question

The initial and final temperature of same body are (25 + 0.1 )o C and (50 + 0.2)°C. What is the % Error in rise in temperature?

Answer 1

Answer:

initial and final temperature of same body are (25 + 0.1 )o C and (50 + 0.2)°C

spheres A and B made of the same material have radii rA and rB respectively.both the spheres are cooled from the same temperature under the conditions valid for Newton's law of cooling.the ratio of the rate of change of initial and final temperature of same body are (25 + 0.1 )o C and (50 + 0.2)°C
