Answer:
c. "Ohmic" is when the plot of I [Amp] versus V [Volt] has a slope equal to R.
Explanation:
A resistor is said to be Ohmic if it obeys ohms law. In am Ohmic resistor, the resistance is constant regardless of the current passing through it. Graphically, an ohmic resistor as a linear relationship when its current and voltage relationship is presented graphically.
Answer:

Explanation:
Let's use the decay equation.

Where:
- A is the activity at t time
- A₀ is the initial activity
- λ is the decay constant
We know that 
So we have:
