Answer: B
Explanation: If she is interested in it then yes
"Frequency" is a measure of how frequent something is.
Its unit is the "Hertz".
1 Hertz = 1 per second
The speed of the wave in water is 833.33 m/s
The given parameters;
- depth of the wrecked ship, d = 1000 m
- frequency of the wave transmitted, f = 50 kHz
- time of motion of the echo, t = 2.4 s
The speed of the wave in water is calculated by applying echo equation as shown below;

Thus, the speed of the wave in water is 833.33 m/s

Answer:
D, I think.
Explanation:
I had a quiz in Plate Tectonics and there was 2 questions that are related to this, but not the exact question.
Which material rises from cracks in oceanic crust
-molten rock
Which is the first step in the seafloor spreading process?
-a crack forms in oceanic crust.
those are all right btw, so you can decide if the answer I told you is right or not.
Answer:
<em>199,430Joules</em>
Explanation:
Gravitational potential energy is the energy possessed by a falling object due to virtue of its position.
gravitational potential energy = mass * acceleration due to gravity * height
gravitational potential energy = 55 * 9.8 * 370
gravitational potential energy = 539 * 370
gravitational potential energy = 199,430
<em>Hence the total change in the skier's gravitational potential energy is 199,430Joules</em>
