Contrast potential and kinetic energy. Give an example of potential being changed to kinetic energy.

Biology
1 answer:
loris [4]3 years ago

Answer:

First, the raised hammer has more potential energy since it has the potential to go higher or lower. Second, when you hit the hammer on the table, the stored potential energy is converted to kinetic energy as the hammer is falling. (It's the falling hammer that has kinetic energy)

Explanation:

Another example-When rolling a ball down a ramp the ball at its highest point has potential energy but when it rolls down the ramp it converts to kinetic energy

Hope this helps :)

Just like a compass, a modern day gps will say whether you're going north, east, south, or west, however they also tell your exact location and the location that you need to go too.

Think about challenges related to marine science which are currently facing society. In coastal and inland communities alike, th
Alex_Xolod [135]

Global challenges related to marine science are as follows:

1. Ocean acidification is a major issue that affects all of the world's ocean industries and has severe negative effects on the environment, society, and the economy. Coordinated government action is required to effectively address this issue.

<h3>What is impact of ocean acidification?</h3>

Ocean acidification will affect the biological, biogeochemical, and ecological aspects of the oceans, and while the effects on the environment, the socio-ecological system, and human dimensions are all still not fully understood, they have the potential to have very dramatic effects. Numerous marine ecosystem services and goods may be impacted directly or indirectly. Industries that rely on these services from the Ocean are impacted.

2. Overfishing:

Overfishing poses a severe threat to the fish in our water, whether it's for the food industry or the aquarium sector. The Food and Agriculture Organization estimates that more than half of the species of marine fish have been totally or overexploited, despite the fact that many of them simply need to remain in the sea because they are not necessary for food security or because they cannot survive in captivity. We are killing entire ecosystems and the food chains that are necessary to keep them healthy by overfishing. Overfishing not only causes the extinction of entire species, but it also directly affects other species in the food chain.

3. Plastic

Between 1.15 and 2.41 million tons of plastic enter the ocean every single year. The Great Pacific Garbage Patch, which is a collection of rubbish in the Pacific Ocean is now three times the size of France. Animals can get tangled in the huge amount of plastic which litter the ocean, and the plastic smothers and destroys coral and sponges. Plastic bags are also often mistaken for food by sea turtles, and they either become trapped or eat the bag which clogs their digestive system. Plastic continuously breaks down resulting in little pieces of “micro-plastic” that are consumed by a variety of marine life, including several species that humans like to catch and eat.

solutions that account for societal needs and wants:

1. Cutting back on carbon emissions.

2. Reducing plastic usage.

3. Making sure the fish you consume is supplied sustainably and ethically.

4. Participating in beach cleanups.

5. Only purchase aquarium fish that were raised in captivity.

6. Supporting elected officials that favor a wholesome atmosphere

7. Contributing to environmental organizations that protect our oceans.

Review the data table. What conclusion can be drawn from the data shown?
joja [24]

Answer:

B) Styrofoam is a good insulator.

Explanation:

When talking about thermal energy, or a heat, insulator is a material that doesn't allow heat to pass through easily. On the other hand, a conductor is completely the opposite, it allows, quite successfully, transfer of the heat.

So, regarding ice cream, from these definitions above, we can conclude that insulators will prolong melting time, while, in the conductors, ice cream will melt rather fast.

Looking at the table, we see that Styrofoam had the longest melting time, which makes it quite successful insulator.
