Perform the given operation and report the answer with the appropriate number of significant figures. 4.910 km - 0.08 km = ?

4.83 km

Explanation:

Let's consider the following subtraction.

4.910 km - 0.08 km

For an addition or a subtraction, the rule for significant figures is as follows: limit the reported answer to the rightmost column that all numbers have significant figures in common, in this case, 2 figures after the decimal point.

4.910 km - 0.08 km = 4.83 km

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
