How do wind turbines pollute their environment?

Answers

Answer 1

Answer: Although the wind turbines do not pollute the environment directly, it is still able to pollute the environment indirectly. The maintenance, construction, and the assembly of the wind turbines would make use of equipment or machines that would emit some harmful substances. For example, the delivery of the materials, the turbine parts, and the other equipment would entail a lot of back and forth trips. The deliverer, from his vehicle, would sometimes emit smoke or gas from his vehicle that is dangerous to health.

Answer 2

Answer: Wind turbines in fact to pollute the environment. They pollute the environment because when they are being built or manufactured, pollution is produced. Wind power does produce pollution. It also takes up space in land. In farms they take up a lot of space so then we cannot grow crops and animals cannot live there. One turbine can give electricity to about 400 homes. Imagine how many you will need to power a whole country! The turbines are also very loud. It can damage peoples ears when they are near one.

Answers

Answer:

C. 8.56cm

Explanation:

Since we are to get the difference of cord length in centimeter, there fore we will have to convert the one yard and one metre length of wires to centimeters.

For 1m length of cord

1m = 100cm

For 1yard length of cord

1yard = 91.44cm

Difference in cord length = 100cm - 91.44cm

= 8.56cm

Answer:

Explanation:

A meter is 8.56 centimeters longer than a yard. Something to keep in mind is that a meter is about 10% longer than a yard.

If the unemployment rate is rising, what part of the business cycle is the economy most likely experiencing? A. Peak B. Expansion
C. Spiral
D. Recession

Answers

Answer: D. Recession

Explanation:

A recession can be define as the part of the business cycle in which the economy declines for a period of at least six months. The decrease in the economy can be detected by drop in five economic indicators such as employment rate, manufacturing, income, gross domestic product and retail sales.

On the basis of the above explanation, recession is the part of the business cycle in which the unemployment rate rises.

D. Recession

because the unemployment is rising which is more people loosing their jobs and recession means a decline in something

Explanation:

A 15 kg box is sliding down an incline of 35 degrees. The incline has a coefficient of friction of 0.25. If the box starts at rest, how fast is it moving after it travels 3 meters?

Answers

The box has 3 forces acting on it:

• its own weight (magnitude w, pointing downward)

• the normal force of the incline on the box (mag. n, pointing upward perpendicular to the incline)

• friction (mag. f, opposing the box's slide down the incline and parallel to the incline)

Decompose each force into components acting parallel or perpendicular to the incline. (Consult the attached free body diagram.) The normal and friction forces are ready to be used, so that just leaves the weight. If we take the direction in which the box is sliding to be the positive parallel direction, then by Newton's second law, we have

• net parallel force:

∑ F = -f + w sin(35°) = m a

• net perpendicular force:

∑ F = n - w cos(35°) = 0

Solve the net perpendicular force equation for the normal force:

n = w cos(35°)

n = (15 kg) (9.8 m/s²) cos(35°)

n ≈ 120 N

Solve for the mag. of friction:

f = µn

f = 0.25 (120 N)

f ≈ 30 N

Solve the net parallel force equation for the acceleration:

-30 N + (15 kg) (9.8 m/s²) sin(35°) = (15 kg) a

a ≈ (54.3157 N) / (15 kg)

a ≈ 3.6 m/s²

Now solve for the block's speed v given that it starts at rest, with v₀ = 0, and slides down the incline a distance of ∆x = 3 m:

v² - v₀² = 2 a ∆x

v² = 2 (3.6 m/s²) (3 m)

v = √(21.7263 m²/s²)

v ≈ 4.7 m/s
