Question

the initial and the final temperature of a copper sphere was measured by an observer to be (41.2+/-0.1)°c and (31.0-/+0.3)°c respectively change in the temperature of the sphere with proper error limits is​ please help

Answer 1

Given :   the initial and the final temperature of a copper sphere was measured by an observer to be (41.2+/-0.1)°c and (31.0-/+0.3)°c respectively

To Find : change in the temperature of the sphere with proper error limits is​

Solution:

initial temperature of a copper sphere = (41.2+/-0.1)°c

final temperature of a copper sphere = (31.0-/+0.3)°c

change in the temperature  =  41.2 - 31.0  

= 10.2 °C

Error Limits gets added

±-0.1   ,  -/+0.3

= ± 0.4 °C

change in the temperature of the sphere with proper error limits =   10.2  ± 0.4 °C
