Question

How much energy does this wave carry through the window during a 30.0 s commercial?

a) 9.45 × 10³ J
b) 1.35 × 10⁴ J
c) 1.89 × 10⁴ J
d) 2.70 × 10⁴ J

Answer 1

The energy carried by a wave through a window can be calculated using the formula E = Pt where E is the energy, P is the power (energy per unit time), and t is the time. Since the question does not provide the power, we cannot calculate the exact energy.

Step-by-step explanation:

The energy carried by a wave through a window can be calculated using the formula:

E = Pt

where E is the energy, P is the power (energy per unit time), and t is the time. Since the question does not provide the power, we cannot calculate the exact energy. Therefore, we cannot determine which option is correct.
