The statement about "<span>Power is the time rate of change of work" is true. The answer is letter A. Power is presented by the equation P = Wt where P is the power, W is work and t is time.</span>
Answer:
A
Explanation:
If the earthquake occus in the ocean, it can push up powergul waves.
C. have similar properties
(this is because they have the same number of electrons in the outer orbital)
Answer:
The highest pressure is located at points x & y.
Explanation:
The pressure will be greater at the X & y points, because they are at a deeper distance than the Z point. We must remember that the pressure is a function of the depth of the fluid, and is expressed by the following equation.
![P = densi*g*h\\where\\densi = density [kg/m^3]\\g = gravity [m/s^2]\\h = elevation [m]](https://tex.z-dn.net/?f=P%20%3D%20densi%2Ag%2Ah%5C%5Cwhere%5C%5Cdensi%20%3D%20density%20%5Bkg%2Fm%5E3%5D%5C%5Cg%20%3D%20gravity%20%5Bm%2Fs%5E2%5D%5C%5Ch%20%3D%20elevation%20%5Bm%5D)
The pressure is always measured with respect to the liquid level towards the depth of the fluid, so at greater depth greater pressure

The locations at which the amplitude is minimum are called </span>nodes<span>, and the locations where the amplitude is maximum are called </span>antinodes<span>. (most of these aren't my own words but I tried to put some in my own words) :)</span>
