2.) How does hydrokinetic energy connect to circuits?
3.) How does hydrokinetic energy connect to magnets?
4.) How does hydrokinetic energy connect to electrical charges?
5.) How does hydrokinetic energy connect to the parts of waves?
Answer:
1.They generate power only from the kinetic energy of moving water (current).
2.relating to the motions of fluids or the forces which produce or affect such motions — compare hydrostatic.
3. It uses water motion to generate a high-pressure liquid rather than electricity.
4. tidal currents, ocean currents or river currents into electrical power.
5.When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.

Why does mantle rock begin to sink back towards the lower mantle from the area closest to the crust?
(Science/Plate Tectonic Movement)
Answer: Convection Currents
Explanation: The mantle rock is solid and denser because it is cooler. This means it will sink closer to lower mantle as warmer, lense dense rock/magma moves upwards.

Write a short paragraph about electrical current using the terms conductor and insulator.
Answer:
Bet
Explanation:
In a conductor, electric current can flow freely, in an insulator it cannot. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. ... Most atoms hold on to their electrons tightly and are insulators.
Help Please! its another cell functions
Answer: last option!
Explanation:
Answer:
The oxygen molecules will spread out evenly and many will enter the cell by passing through tiny openings in the membrane.
Explanation:
A cell membrane will allow the oxygen to enter by diffusion. Diffusion is the movement of particles from an are of higher concentration to an area of lower concentration. Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion.

What type of tide is Australia likely to be experiencing in the diagram on the RIGHT and why? In your own words explain what is happening?
Answer:
Spring tides are extremely high and extremely low. This is created when the sun and moon pull together.
Explanation:
From the diagram, the type of tide Australia is likely to be experiencing is: neap tides.
A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
Generally, there are two (2) main types of a tide and these include:
High tide.Low tide.Additionally, the two (2) form of a tide are:
I. Spring tide: it occur s twice each month close to the the full and new
moons, especially when the Moon and Sun pull together.
II. Neap tide: it occurs two times in a month when the Moon is close to its first and last quarters, especially when the Moon and Sun pull at a right angle.
From the diagram, the type of tide Australia is likely to be experiencing is neap tides because it happened when the Moon is close to its first and last quarters and the Moon and Sun were pulling at a right angle.

Explanation:
What are three types of variations within populations or species?
Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants
Clouds and fog are water features often associated with condensation. The correct option is C.
The process by which water vapour, a gaseous form of water, changes into liquid water is called condensation.
When warm, moist air meets a cooler surface or when the air itself cools, it happens. As a result of this cooling, water vapour loses energy and condenses into tiny water droplets or ice crystals, which are what are seen as clouds or fog.
Even though the ocean and frozen lakes are both connected to water, condensation is not a direct result of either of these. As opposed to condensation, water vapour rising from plants is a result of transpiration.
Thus, the correct option is C.
