Mention five disadvantages of nonsustainable energy ​

Physics
1 answer:
Hitman42 [59]3 years ago
7 0

Answer:

Explanation:

Even as our global society makes a push toward renewable energy through accords like the Paris agreement, there is still a place in our society for non-renewables.

Fossil fuels give us a way to maintain our current infrastructure while we start developing new ways to produce clean energy. Solar, wind, water, and geothermal resources are all possible because of the manufacturing practices that we have today that use non-renewables.

The definition of a non-renewable energy source is straightforward. If you consume the item and it no longer becomes available for use, then it qualifies as this resource. Renewables are resources that are always present in some way.

As new technologies allow us to be more efficient with our fossil fuels, a review of the advantages and disadvantages of non-renewable energy gives us a way to examine this still essential resource.

List of the Advantages of Non-Renewable Energy

1. We can prepare non-renewable supplies at almost any location.

If we want to control energy from renewables, then we must identify regions globally that support this outcome. This issue applies to solar, wind, and even geothermal for some geographic locations. Some locations are not well-suited to the production of renewable energy.

It is not an issue for non-renewables because we can develop processing stations everywhere to establish their refinement and distillation. Although problems with transport loss occur when using them, a well-developed infrastructure can reduce this predicament rather effectively.

2. Non-renewables produce more power after the refinement process.

When we process non-renewables to seize the energy potential offered, we can generate more power from crude oil, natural gas, and other fuels than what they provide in their raw format.

If we take a single barrel of crude oil, then it provides 42 gallons of product to use at our discretion. When we complete the work of preparing this non-renewable, then the yield gives us the equivalent of more than 44 gallons of finished products. That means we attain 6% more energy potential when using fossil fuels, and that’s a total that renewables can’t replicate.

3. Thousands of unique products come from non-renewables.

A baseball bat hits a baseball with a force of 100 newtons. What is the force and its direction exerted by the ball on the bat?
Brut [27]

Answer:

The force exerted by the ball on the bat has a magnitude of 100 N and its direction is exactly opposite to that of the force exerted by the bat on the ball.

Explanation:

Recall that Newton's third law tells us that : "For every action, there is an equal and opposite reaction."

Therefore if the bat acts on the ball with a force of 100 N, the ball acts on the bat with a similar magnitude of force (100 N) but direction opposite to the original force.

to measure the static friction coefficient between a block and a vertical wall, a spring is attached to the block, is pushed on
Stolb23 [73]

Answer:

μ = mg/kx

Explanation:

Since the bock does not slip, the frictional force equals the weight of the block. So, F = mg. Now, the frictional force, F = μN where μ = coefficient of static friction and N = Normal force.

Now, the normal force equals the spring force F' = kx where k = spring constant and x = compression of spring.

N = F' = kx

So, F = μN = μkx

μkx = mg

So, μ = mg/kx

A bug flying horizontally at 0.65 m/s collides and sticks to the end of a uniform stick hanging vertically. After the impact, th
irina [24]

The angular momentum is defined as,

L=I\omega

Acording to this text we know for conservation of angular momentum that

L_i=L_f

Where L_iis initial momentum

L_f is the final momentum

How there is a difference between the stick mass and the bug mass, we define that

Mass of the bug= m

Mass of the stick=10m

At the point 0 we have that,

L_i=mvl

Where l is the lenght of the stick which is also the perpendicular distance of the bug's velocity

vector from the point of reference (O), and ve is the velocity

At the end with the collition we have

L_f=(I_b+I_s)\omega

Substituting

L_f=(ml^2+\frac{10ml^2}{3})\omega

L_f=\frac{13}{10}ml^2w

m(0.65)l=\frac{13}{10}ml^2 \omega

\omega=\frac{1}{2l}

Applying conservative energy equation we have

\frac{1}{2}(I_b+I_s)\omega^2=mgh+10mgh'

\frac{1}{2}(ml^2+\frac{10ml^2}{3})(\frac{1}{2l})^2=mg(l-lcos\theta)+\frac{10}{2}mg(l-lcos\theta)

Replacing the values and solving

l=\frac{13}{0.54g}

Substituting

l=\frac{13}{0.54(9.8)}

l=2.45cm
