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.

Of the choices below, which best describes the effect predation has on the predator/prey organisms involved in the relationship?
steposvetlana [31]

Answer:

The correct answer is C. benefit ... harmed

Explanation:

Predation is a type of interaction between two individuals in which one individual gets harmed which is called prey and another organism who is predator gets benefitted.

In predation, the predator kills its prey and consume it to survive. For example, Lion is a predator and deer is the prey so during predation lion kills the deer and consume it so here lions get benefited by consuming deer and deer is harmed as it lost its life. So the correct answer is C. benefit ... harmed.

Which organisms convert nitrogen into a form that is usable by<br> humans
ycow [4]

there are two or three types or methods in which they change according to the class you study so this a answer from a 8th grader ( there are difference in classes)

<u>Nitriates</u> are a form of <u>nitrogen</u> that is usable by plants.

It is assimilated into plant tissue as protein. The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.

Nitrification is the conversion of ammonia (NH3) to nitrate (NO3). It is usually performed by soil living bacteria, such as nitrobacter. This is important because plants can assimilate nitrate into their tissues, and they rely on bacteria to convert it from ammonia to a usable form.

denitrifying bacteria convert nitrogen into ammonia which is a form of nitrogen that is useful to humans. Bacteria "fixes" gaseous nitrogen into nitrogen usable by plants in the form of nitrate.

4. Discuss the difference between solar flares and CME's.
brilliants [131]

Answer:

CMEs are giant clouds of particles from the Sun hurled out into space, while flares are flashes of light—occurring in various wavelengths—on the Sun.

All three occur in the corona. The biggest difference is the cause. The solar wind is a constant flow of particles from the sun’s corona due to their high energy gained from the sun’s interior, it’s like being boiled off. CME’s and flares are the result of “explosive” releases of energy from the sun’s magnetic field.

One can think of the explosions using the physics of a cannon. The flare is like the muzzle flash, which can be seen anywhere in the vicinity. The CME is like the cannonball, propelled forward in a single, preferential direction, this mass ejected from the barrel only affecting a targeted area.
