Explanation

Step 1: Recall Ohm's Law

V = IR, where V is voltage, I is current, and R is resistance.

Step 2: Convert current to amperes

300 mA = 0.3$ A

Step 3: Calculate the resistance

R = V/I = 1.5/0.3 = 5 Ω

Explanation

The formula ∑x/n calculates the arithmetic mean of a set of numbers, where:

∑x = sum of all values

n = number of values

This formula provides the average value of the dataset.

Explanation

The absorption of X-rays in a given material follows an exponential curve, described by the Beer-Lambert law:

I(x) = I₀ × e^(-μx)

where I(x) is the intensity of the X-rays after passing through a thickness x of the material, I₀ is the initial intensity, μ is the linear attenuation coefficient, and x is the thickness of the material.
