Mention five disadvantages of nonsustainable energy ​

Physics
1 answer:
Hitman42 [59]3 years ago

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.

An 8.0 m, 240 N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground
sweet [91]

Answer:

5.7 m

Explanation:

AD = length of the ladder = L = 8 m

AB = distance of the center of mass of the ladder = (0.5) L = (0.5) 8 = 4 m

AC = distance of person on the ladder from the bottom end = x

W = weight of the ladder = 240 N

F_{g} = weight of the person = 710 N

F = force by the wall on the ladder

N = normal force by ground on the ladder = ?

Using equilibrium of force along the vertical direction

N = F_{g} + W

N = 710 + 240

N = 950 N

μ = Coefficient of static friction = 0.55

f =static frictional force on the ladder

Static frictional force is given as

f = μ N

f = (0.55) (950)

f = 522.5 N

Force equation along the horizontal direction is given as

F = f

F = 522.5 N

using equilibrium of torque about point A

F Sin50 (AD) = W Cos50 (AB) + (F_{g} Cos50 (AC))

(522.5) Sin50 (8) = (240) Cos50 (4) + (710) Cos50 (x)

x = 5.7 m

A flashlight contains a battery of two cells in series, with a bulb of resistance 12 Ohms. The internal resistance of each cell
Elina [12.6K]

Answer:

1.5024

Explanation:

Draw a diagram. Put the two cells in series. Now draw 3 resistors. Two of them equal 0.26 ohms each. The third one is the lightbulb which is 12 ohms.

R = 0.26 + 0.26 + 12 = 12.52

The bulb has a voltage of 2.88 volts across it. You can get the current from that.

i = E / R

i = 2.88 / 12 =

i = 0.24 amps.

Now you can get the voltage drop across the two cells.

E = ?

R = 0.26

i = 0.24 amps

E = 0.26 * 0.24

E = 0. 0624

Finally divide the 2.88 by 2 to get 1.44

Each cell has an emf of 1.44 + 0.0624 = 1.5024
