Answer:

The energy increases by a factor of 1.2.

Explanation:

The energy (E) of an ocean wave is directly proportional to the square of its amplitude (A).

E ∝ A² or E = kA²

If you have two waves with amplitudes A₁ and A₂, then

$\frac{E_{2} }{E_{1} } = \frac{A_{2}^{2} }{A_{1}^{2} } = (\frac{A_{2} }{A_{1} }})^{2}$

If A₂ = 1.1A₁, then

$E_{2} = E_{1} \times (\frac{1.1A_{1} }{A_{1} })^{2} = (1.1)^{2} = 1.2$

The energy increases by a factor of 1.2.

To convert 78.1 g of water at 0° C to Ice at -57.1°C; we can do it in steps;
1. Water at 0°C to ice at 0°C
The heat of fusion of ice is 334 J/g;
Heat = 78.1 × 334 = 26085.4 Joules
2. Ice at 0°C to -57.1°C
Specific heat of ice is 2.108 J/g
Heat = 78.1 × 2.108 J/g = 164.6348 Joules
Thus the total heat energy released will be; 26085.4 + 164.6348
= 26250.0348 J or 26.250 kJ
