Among the options listed, land does not depreciate, unlike computers, trucks, and buildings, which lose value over time due to use and aging. Land typically appreciates in value due to its limited availability and increasing demand. Thus, the correct choice in this context is land. ;

Approximately 2.81 x 10^21 electrons flow through an electric device delivering a current of 15.0 A for 30 seconds. This is based on the relationship between current, charge, and the number of electrons. The total charge delivered in this time can be calculated using the formula Q = I × t, and the number of electrons by dividing this charge by the charge of a single electron.
