<span>The density of the energy that is transported under the waves under the ocean surface is about five times higher compared to the wind energy 20 meter (about 65 feet) above. In other words, the amount of energy in a single wave is very high. However it turns out that when they tried to make the high power of the waves to power things in a house it only made it past the first few stages there were very few that made it to some stages. This started taking place in around 2001. hope this helped if not let me know and i could explain more:)

when two waves superimposed then the resultant wave will have more energy and more intensity
It is because the resultant amplitude will be increased and given by the following equation
so here due to superposition since amplitude is increased so the energy or power of the wave will be increased
There is no effect on frequency , tension and density after superposition of waves and it will remain the same
SO energy is given as
here k = constant
A = amplitude
Answer:
10.65 m/s
Explanation:
Given that an Olympic diver is on a diving platform 5.70 m above the water. To start her dive, she runs off of the platform with a speed of 1.27 m/s in the horizontal direction.
Her initial velocity U = 1.27 m/s
The height H = 5.7 m
The final velocity V will be calculated by using the formula;
V^2 = U^2 + 2gH
Substitute U, g and H into the formula
V^2 = 1.27^2 + 2 × 9.8 × 5.7
V^2 = 1.6129 + 111.72
V^2 = 113.33
V = sqrt ( 113.33)
V = 10.65 m/s
Therefore, the diver's speed, in m/s, just before she enters the water is 10.65
Answer:
She should braise it
Explanation:
Joan purchased a large, tough cut of beef. To make the meat more tender, she should braise it.
Braising begins with dry heat and ends with moist heat. At high temperatures, beef is seared in a heavy-bottomed Dutch oven to attain a caramelized crust. Then cover and finish cooking in a liquid at lower temperatures.
