Explanation:
Potential energy is energy that is built up and saved. When you are moving and letting out that energy, that is kinetic energy. You would be using the least kinetic energy when you aren't moving, which is at the top of the hill because you move faster the more you go down.
It was be at least 67 cm/yr for the North Atlantic
Answer:
If a chord had notes with frequencies of 100, 1,000, and 6,000 Hz, the basilar membran would vibrate at multiple positions, with peaks at A, B, and C.
Explanation:
The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s is 107 s
<h3>Data obtained from the question</h3>
The following data were obtained from the question given above:
- Initial velocity (u) = 11.1 Km/s
- Final velocity (v) = 11.7 Km/s
- Distance (s) = 1220 Km
- Time (t) =?
<h3>How to determine the time</h3>
The time taken for the spaceship to increase its speed from 11.1 km/s to 11.7 km/s can be obtained as illustrated below:
s = (u + v)t / 2
Cross multiply
(u + v)t = 2s
Divide both sides by (u + v)
t = 2s / (u + v)t
t = (2 × 1220) / (11.1 + 11.7)
t = 2440 / 22.8
t = 107 s
Thus, the time taken for the spaceship to change its speed is 107 s

Answer:
Explanation:
Hydrostatics put simply means fluids at rest (hydro-fluid, static-rest)
Oceans are basically bodies of fluid (water),
and as such they are in hydrostatic equilibrium or hydrostatic balance when they are at rest, or when the velocity of flow in them are constant over a given time. Hydrostatic equilibrium usually occurs when external forces acting on the ocean bodies balance each other out. An example is the force of gravity being balanced by a pressure-gradient force.
The pressure felt by a body in a fluid (water) is given by the formula P = ρgh
Where ρ is the density of the fluid
g is acceleration due to gravity
h is the depth of the body in the fluid.
ρg is constant for water and as a result the pressure you will feel in an ocean will depend on how far below the surface you are, h. The lower inside the water you are the higher the pressure you feel.
