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.

A rectangular coil lies flat on a horizontal surface. A bar magnet is held above the center of the coil with its north pole poin
Llana [10]

Answer:

<em>There is no induced current on the coil.</em>

Explanation:

Current is induced in a coil or a circuit, when there is a break of flux linkage. A break in flux linkage is caused by a changing magnetic field, and must be achieved by a relative motion between the coil and the magnet. Holding the magnet above the center of the coil will cause no changing magnetic filed since there is no relative motion between the coil and the magnet.

Attempt 2 You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 15151515 l
Natasha_Volkova [10]

Answer:

v = 28.98 ft / s

Explanation:

For this problem we must solve it in parts, let's start by looking for the speed of the two cars after the collision

In the exercise they indicate the weight of each car

          Wₐ = 1500 lb

          W_b = 1125 lb

Car B's velocity from v_b = 42.0 mph westward, car A travels east

let's find the mass of the vehicles

             W = mg

             m = W / g

             mₐ = Wₐ / g

             m_b = W_b / g

             mₐ = 1500/32 = 46.875 slug

             m_b = 125/32 = 35,156 slug

Let's reduce to the english system

             v_b = 42.0 mph (5280 foot / 1 mile) (1h / 3600s) = 61.6 ft / s

We define a system formed by the two vehicles, so that the forces during the crash have been internal and the moment is preserved

we assume the direction to the east (right) positive

initial instant. Before the crash

           p₀ = mₐ v₀ₐ - m_b v_{ob}

final instant. Right after the crash

           p_f = (mₐ + m_b) v

the moment is preserved

           p₀ = p_f

           mₐ v₀ₐ - m_b v_{ob} = (mₐ + m_b) v

           v = \frac{ m_a \ v_{oa} - m_b \ v_{ob}  }{ m_a +m_b}

we substitute the values

           v = \frac{ 46.875}{82.03} \ v_{oa} -  \frac{35.156}{82.03} \ 61.6

           v = 0.559 v₀ₐ - 26.40                  (1)

Now as the two vehicles united we can use the relationship between work and kinetic energy

the total mass is

              M = mₐ + m_b

              M = 46,875 + 35,156 = 82,031 slug

starting point. Jsto after the crash

              K₀ = ½ M v²

final point. When they stop

             K_f = 0

The work is

             W = - fr x

the negative sign is because the friction forces are always opposite to the displacement

Let's write Newton's second law

Axis y

           N-W = 0

           N = W

the friction force has the expression

            fr = μ N

we substitute

            -μ W x = Kf - Ko

             

            -μ W x = 0 - ½ (W / g) v²

            v² = 2 μ g x  

            v = \sqrt{ 2 \ 0.750 \ 32 \ 17.5}Ra (2 0.750 32 17.5  

            v = 28.98 ft / s

Sarah is 14 years old and skips school twice a week without any written explanation. What can she be charged with?
harina [27]

Answer:

Too many people are unaware or indifferent to that.” Fines can cost up to $500 per truancy, due within 30 days unless a judge gives an extension. For many students and families, it's another debt they can't pay. And if fines aren't paid, they can convert into an arrest warrant when a student turns 17.

Kalisha is going to cut the remaining 21 1/2 buns into thirds. How many 1/3 size buns will she have?
baherus [9]
Total buns = 21 1/2 = 43/2 buns
1/3 size buns would be: 43/2 / 1/3 = 43*3 / 2 = 129/2

In short, Your Answer would be 129/2 or 64 1/2 or 64.5

Hope this helps!
