Answer:

noise pollution

Explanation:

Visual pollution may be defined as a pollution that obstructs a view. It impairs one ability to see and enjoy a pleasant view. It is considered as an aesthetic issue.

The rotating blades of the windmill causes visual disturbances by intercepting the light of the sun and it causes moving shadows and the light flashes from the reflection of the sun. It also causes noise or sound as the blades rotates. Thus the combination of visual and acoustics exposures leads to the negative assessment of the windmills.

Therefore, people living near wind farms objects the windmills as they causes visual pollution as well as noise pollution.

Neporo4naja [7]

Explanation :

The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time.

Initially, ice is heated until its temperature reaches $0^0\ C$ and changes to liquid state.

From the attached graph it is clear that until $100^0\ C$ the temperature will rise steadily. Here, the liquid begins to vaporize. Vaporization is the state of matter at which liquid state changes to the gaseous state.

So, E is the point which shows the gaseous state.

Select the statements that are TRUE. Electrophilic aromatic substitution reactions have energies of activation that are very low

NikAS [45]

Answer:

Addition reactions with benzenes lead to the loss of aromaticity.

Benzene and its derivatives undergo a type of substitution reaction in which a hydrogen atom is replaced by a substituent, but the stable aromatic benzene ring is regenerated at the end of the mechanism.

Benzene and its derivatives tend to undergo electrophilic aromatic substitution reactions.

Consider a situation of simple harmonic motion in which the distance between the endpoints is 2.39 m and exactly 8 cycles are co

aivan3 [116]

Answer:

1.195 m

2.8375 s

2.21433 rad/s

Explanation:

d = Distance = 2.39 m

N = Number of cycles = 8

t = Time to complete 8 cycles = 22.7 s

Radius would be equal to the distance divided by 2

$r=\frac{d}{2}\\\Rightarrow r=\frac{2.39}{2}\\\Rightarrow r=1.195\ m$

The radius is 1.195 m

Time period would be given by

$T=\frac{t}{N}\\\Rightarrow T=\frac{22.7}{8}\\\Rightarrow T=2.8375\ s$

Time period of the motion is 2.8375 s

Angular speed is given by

$\omega=\frac{2\pi}{T}\\\Rightarrow \omega=\frac{2\pi}{2.8375}\\\Rightarrow \omega=2.21433\ rad/s$

The angular speed of the motion is 2.21433 rad/s
