Answer: the constant of proportionality is 2.5 ohms
Step-by-step explanation:
If two quantities are directly proportional, it means that an increase in the value of one quantity would cause a corresponding increase in the other quantity. Also, a decrease in the value of one quantity would cause a corresponding decrease in the other quantity.
Given that Voltage, V is directly proportional to current,I, if we introduce a constant of proportionality, k, the expression becomes
V = kI
If V = 5 volts when I = 2 amps, then
5 = 2k
k = 5/2 = 2.5 ohms

Answer:
htdxdfdfg
Step-by-step explanation:
The temperature rose so you add the amount it rose to the starting temperature
68.7 + 9 = 77.7 degrees
It then dropped so mow you subtract t the amount it dropped:
77.7 - 12.3 = 65.4 degrees
The answer is 65.4 degrees
