Climate change cannot be measured by a single instrument but rather through various methods like temperature monitoring, gas analysis, and ice core sampling. Each of these tools provides valuable data that collectively informs our understanding of climate dynamics. A combination of instrumentation is essential to grasp the full scope of climate change. ;
Approximately 3.5 x 10^20 electrons flow through an electric device that carries a current of 15.0 A for 30 seconds. This calculation involves finding the total charge using the formula Q = I × t and then converting that charge into the number of electrons using the charge of a single electron.
