Final answer:

To determine the mass of the TV from its weight in newtons, divide the weight by the gravitational acceleration. The resulting mass is 15.00 kilograms, corresponding to option b).

Step-by-step explanation:

The question relates to the conversion of newtons (N) to kilograms (kg) using Earth's gravitational acceleration. To find the mass of the TV in kilograms, we use the formula for weight w = mg, where w is weight in newtons, m is mass in kilograms, and g is the gravitational acceleration, which is 9.8 N/kg on Earth. Given the weight of the TV is 147 newtons, the mass (m) can be calculated by dividing the weight (w) by the acceleration due to gravity (g).

m = w/g = 147 N / 9.8 N/kg = 15.00 kg

Therefore, the mass of the TV is 15.00 kilograms, making option b) the correct answer.
