The energy of a wave is directly proportional to the square of the waves amplitude. Therefore, E = A² where A is the amplitude. This therefore means when the amplitude of a wave is doubled the energy will be quadrupled, when the amplitude is tripled the energy increases by a nine fold and so on.
Thus, in this case if the energy is 4J, then the amplitude will be √4 = 2 .

3i +3j + (3i -3j) = ?
3i + 3j + 3i -3j =?
= 6i + 0j</span>
The pressure exerted by a fluid solely relies on the depth or height of the fluid, its density, and the gravitational constant. These three are related in the equation:
Pressure = density x g x height
In the problem, point A is within the block inside the tank. The water above the block is assumed to be 0.6 meters. This gives a point A pressure of:
P = 1000 kg/m^3 * 9.81 m/s^2 * 0.6 m = 5,886 Pa or 5.88KPa
Volcanic islands, Mountain ranges
Explanation:
A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.
- An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
- As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
- Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
- The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.
