The answer would be (option B) - When an object falls, its gravitational potential energy is changed to kinetic energy. You can use this relationship to calculate the speed of the object’s descent. Gravitational potential energy for a mass m at height h near the surface of the Earth is mgh more than the potential energy would be at height 0. (It’s up to you where you choose height 0.)

The answer is 
B) a flowerpot falling from a balcony.
This is the answer because potential energy is basically when something is standing still. Kinetic energy is the opposite, its when something is moving. So the flowerpot was still but something knocked it over and the potential energy was turned into kinetic energy. In option A, the kinetic energy is being turned into potential energy singe the car stopped moving. In option C, the cow is just storing potential energy and it is not being transformed into kinetic energy since the cow is not moving. Option D is not the answer because once again, this says the bike is slowing down, which means that the kinetic energy is decreasing and being turned into potential energy.

Describes how energy is produced from the power of water. In your answer, include the terms: ocean water, turbine, electricity,
lapo4ka [179]

Most hydroelectric power plants have a dam and a reservoir. These structures may obstruct fish migration and affect their populations. Operating a hydroelectric power plant may also change the water temperature and the river's flow. These changes may harm native plants and animals in the river and on land. Reservoirs may cover people's homes, important natural areas, agricultural land, and archaeological sites. So building dams can require relocating people. Methane, a strong greenhouse gas, may also form in some reservoirs and be emitted to the atmosphere. Reservoir construction is "drying up" in the United States  Gosh, hydroelectric power sounds great -- so why don't we use it to produce all of our power? Mainly because you need lots of water and a lot of land where you can build a dam and reservoir, which all takes a LOT of money, time, and construction. In fact, most of the good spots to locate hydro plants have already been taken. In the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power, but the number is down to about 10 percent today. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community.  As this chart shows, the construction of surface reservoirs has slowed considerably in recent years. In the middle of the 20th Century, when urbanization was occurring at a rapid rate, many reservoirs were constructed to serve peoples' rising demand for water and power. Since  Hydroelectric energy is produced by the force of falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Building up behind a high dam, water accumulates potential energy. This is transformed into mechanical energy when the water rushes down the sluice and strikes the rotary blades of turbine. The turbine's rotation spins electromagnets which generate current in stationary coils of wire. Finally, the current is put through a transformer where the voltage is increased for long distance transmission over power lines.   Hydroelectric-power production in the United States and the world!

Cells relate to your genes via genetic code. The genetic code is also what tells the cells what type of cell to become (brain cell, stomach cell, etc.)

What type of rock is formed from compaction or cementation?
Marina CMI [18]
Sedimentary rocks are formed by cementation and compaction. This happens when sediment particles are compressed and fused together over very long periods of time.
