2. How much Potential Energy is gained when a 1250 N mass is raised a vertical distance of<br>35 m?​
vichka [17]

Potential Energy

The potential energy gained is 43750 J

Explanation:

Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.

For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.

Potential Energy is defined as

Potential energy = Mass * height

Given Mass M = 1250 N

Given height h = 35 m

So the potential energy = 1250 * 35 = 43750 J

Thus the potential energy is 43750 J

Today, land in urban areas typically is used for housing, transportation, and other structures, rather than for agriculture.
kari74 [83]

Answer: D.  transportation time and shipping costs being reduced

Explanation:

As a result of advancements in transportation of goods across different areas, getting agricultural produce from rural to urban areas became cheaper and more efficient. This reduced the need for people to have to engage in Agriculture in the urban areas since they could just buy the produce they wanted relatively easily.

This freed up land for other ventures such as more housing, business and sports centres as well as other structures and not forgetting areas reserved for the facilities needed to transport the goods from other areas to urban areas.

The luminosity of a star changes throughout its life. For a star of 1Msun, rank the stages a. Red against just before the helium
MrRa [10]

Answer:

  • d. Proto-star at the end of the Hayashi track.
  • c. On the main sequence.
  • a. Red against just before the helium flash
  • b. Horizontal branch
  • e. White dwarf

Explanation:

  • The protostar is a new star that is formed at the end of the Hayashi track and is luminosity temperature relationship of infant stars that are less than M 3. The protostar ends its period and becomes a Tauri star that is extremely luminous.  
  • After which the main sequence of the stars are formed is the next stage in stellar evolution and is dependent on its mass like the sun after this period the star turn red as it has a hydrogen-rich core and it starts to branch out displaying extreme density.
  • The last stage is the white dwarf star as the star has degenerate and left is the exhaust core which is very dense.

Describe 1 environmental issue in Europe and how they affect the environment and its citizens. What can be done to correct this
sertanlavr [38]

Answer: Plastic Pollution

In 1950, the world produced more than 2 million tons of plastic per year. By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment.  

A report by science journal, Nature, determined that currently, roughly 11 million tons of plastic make its way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics into this, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040.

Shockingly, National Geographic found that 91% of all plastic that has ever been made is not recycled, representing not only one of the biggest environmental problems of our lifetime, but another massive market failure. Considering that plastic takes 400 years to decompose, it will be many generations until it ceases to exist. There’s no telling what the irreversible effects of plastic pollution will have on the environment in the long run.
