Answer:

We get non-renewable energy from sources that will run out or will not be replenished in our life times or in many, lifetimes.

Most non-renewable energy sources are fossil fuels like : coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360-300 million years ago) is called the Carboniferous Period.

Explanation:

Fossil fuels ,coal, oil, and natural gas, do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

We don't really like using renewable like solar , wind , water etc I think it's due to the fact that they make life easier, and i think to process renewable energy takes time and money but it causes less harm so , see countries like China, Russia, and Japan . They are mainstays on all three lists. It's also worth noting the countries that are highly dependent on nonrenewable energy sources even though they do not consume as much.

But there is a new development as countries have started leading the way in using renewable energy .Countries like

Iceland. Iceland generates the most clean electricity per person on earth, with almost 100% of its energy coming from renewable sources that make the most of its unique landscape. ...

Sweden.

Costa Rica.

Nicaragua.

United Kingdom.

Germany.

Uruguay.

Denmark.

and surprisingly China

They may be the world’s largest polluter, but China is also the world’s biggest investor in renewable energy, with huge investment levels both at home and overseas. China now owns: five of the world’s six largest solar-module manufacturing firms; the largest wind-turbine manufacturer; the world’s largest lithium ion manufacturer; and the world’s largest electricity utility.

Morocco

Morocco is a country with an abundance of sunshine (up to 350 days a year), so it has wisely decided to invest heavily in solar powered energy production. The first phase of the world’s biggest concentrated solar plant recently opened in Morocco and in combination with their wind and hydro production facilities, is predicted to produce enough energy for more than one million years

USA

The United States of America has one of the world’s largest installed solar PV capacities and an installed wind energy capacity second only to China. But it is also one of the world’s biggest energy consumers, which tends to cancel out much of its renewable capacity. Nevertheless, if more attention was paid to renewables over fossil fuels, it has been estimated that the U.S. could reduce its emissions by almost 80% in only 15 years, without impacting on consumer electricity costs.

Kenya

In the past, Kenya has been forced to import electricity from neighbouring countries, but they are working hard to reverse this by investing heavily in geothermal energy production, which accounted for more than half their energy mix in 2015. They also have Africa’s largest wind farm, providing another 20% of their installed electricity generating capacity.

I hope it helps plz mark me brainliest:)

Answer:

Because it makes our lives easier.

Explanation:

When we talk about nonrenewable resources, it's usually fossil fuels that derive from crude oil. After dividing the useless crude oil into different fractions, you get gases, petrol, kerosene, diesel, fuel oil and bitumen. Each fraction has their own unique purpose i.e: petrol as a fuel for cars.

We use plastic bags for our ease. They consist of a long chain of 'alkenes' that's called poly(ethylene). The long chain was made by smaller molecules from crude oil.

When these bags are burnt for disposal, they release toxic fumes. One being carbon monoxide.

When a second student joins the first, the height difference between the liquid levels in the right and left pistons is 40 cm .
vlada-n [284]

Answer:

m = 56.5 kg

Explanation:

Since the addition of mass on one piston caused a change in pressure head at the other. Diameter of the piston calculated is used as 0.46 m

Δm*g / Area = p * g * Δh   ..... Eq1

m = \frac{p*h*A}{g}

m = \frac{850 * 0.4 * pi*0.46^2}{4*9.81}\\\\m= 56.5 kg

Where c is a constant that depends on the initial gas pressure behind the projectile. The initial position of the projectile is
Ronch [10]

Complete Question

A gas gun uses high pressure gas tp accelerate projectile through the gun barrel.

If the acceleration of the projective is : a = c/s m/s​2

Where c is a constant that depends on the initial gas pressure behind the projectile. The initial position of the projectile is s= 1.5m and the projectile is initially at rest. The projectile accelerates until it reaches the end of the barrel at s=3m. What is the value of the constant c such that the projectile leaves the barrel with velocity of 200m/s?

Answer:

The value of the constant is  c = 28853.78 \ m^2 /s^2

Explanation:

From the question we are told that

         The acceleration is  a =  \frac{c}{s}\   m/s^2

         The  initial position of the projectile is s= 1.5m

         The final position of the projectile is s_f =  3 \ m

          The velocity is  v = 200 \ m/s

     Generally  time  =  \frac{ds}{dv}

   and  acceleration is a =  \frac{v}{time }

so

            a = v  \frac{dv}{ds}

 =>        vdv  =  a ds

             vdv  = \frac{c}{s}  ds

integrating both sides

           \int\limits^a_b  vdv  = \int\limits^c_d \frac{c}{s}  ds

Now for the limit

          a =  200 m/s

             b = 0 m/s  

         c = s= 3 m

          d =s_f= 1.5 m

So we have  

           \int\limits^{200}_{0}  vdv  = \int\limits^{3}_{1.5} \frac{c}{s}  ds

              [\frac{v^2}{2} ] \left | 200} \atop {0}} \right.  = c [ln s]\left | 3} \atop {1.5}} \right.

            \frac{200^2}{2}  =  c ln[\frac{3}{1.5} ]

=>           c = \frac{20000}{0.69315}

              c = 28853.78 \ m^2 /s^2

The temperature at 8:00
musickatia [10]
Change in temperature = final temperature - Initial temperature 
Δt = t₂ - t₁
Δt = 17 - (-6)
Δt = 17 + 6 = 23 f

In short, Your Answer would be Option D

Hope this helps!
