In some areas, farmers have installed windmills to generate electricity to run the farm. Some are generating a surplus of electr

icity and selling it back to the power company. The local power company burns fossil fuels, which pollute the environment, to generate electricity. Windmills do not pollute the environment. Evaluate the statements and choose the statement that best describes how the windmill technology benefits the environment. (2 points)
Windmill technology is a valuable resource that should be used whenever possible. The great advantage is that it uses a nonrenewable resource, the wind, to generate electricity. This is an advantage because nonrenewable resources will always be available.

Windmill technology allows individuals to generate power without polluting the environment. Some individuals could make money selling the power to the power company. This extra money will make the farmers' lives better.

Windmill technology can generate power using a renewable source of energy that does not pollute the environment. By generating a surplus of energy, individuals can sell it to the power company which can replace the energy generated by burning fossil fuels.

Windmill technology might use a renewable resource to generate power but putting the windmills up along the farms damages the environment. The advantage of using a renewable resource to generate power is less important than keeping farms free of windmills that might take up space.

Answer:

Option (3)

Explanation:

Windmills are usually considered to be a structure that is commonly used in the region where there is a high amount of wind supply and converts the wind energy into electrical energy.

Wind is a renewable resource as it can be regenerated, and it does not emit any kind of harmful gases that can pollute the environment.

As these windmills produce electricity, it is being used by the farmers in the given region, and the excess amount of energy is sold to the various power companies by the individuals. This electrical energy so produced directly replaces the fossil fuels, that emits a significant amount of carbon and affects the environment.

Thus, the correct answer is option (3).

Angelina jumps off a stool. As she is falling, the Earth’s gravitational force on her is larger in magnitude than the gravitatio
valentinak56 [21]
The answer is True. The amount force exerted by any object is directly proportional to its mass. This means that our planet is exerting more gravitational force to Angelina, and Angelina is also exerting a gravitational force on our planet directly proportional to her mass. Angelina is actually falling towards the center of the earth,and also our planet is also moving towards Angelina, but it seems negligible with respect to Angelina.Our Sun is so massive that it held our planet in its orbit because of its gravitational force.

A triangular plate with a non-uniform areal density has a mass M=0.500 kg. It is suspended by a pivot at P and can oscillate as
malfutka [58]

The period of the oscillations.T = 1.2042s

Opposition is the process of any quantity or measure fluctuating repeatedly about its equilibrium value throughout time. This process is referred to as oscillation. Oscillation, a periodic fluctuation of a substance, can also be described as alternating between two values or rotating around a central value.

Typically, the mathematical formula for the moment of inertia is

T = 2 π √(I / mgd)

Therefore, a moment of inertia

I = 9.00×10-3 + md^2 ;

I=9.00*10^{-3}+ 0.5 * 0.3^2

I=0.054

T=2\pi \sqrt{0.5*9.8*0.3}

T=1.2042s

The period of the oscillations.T = 1.2042s

Compare how magnetic forces act through non-magnetic materials and<br>magnetic materials:​
gavmur [86]

<h2>Compare how magnetic forces act through non-magnetic materials and </h2><h2>magnetic materials:​</h2>

Explanation:

Magnet

• Magnet :- is an object which attracts pieces of iron, steel etc towards itself.  

Some facts about magnets:-  

• When magnet is freely suspended it always align towards north-south direction    

• Like poles always repel  & opp. poles attract each other.  

• Magnet always exist as dipole    

• Two poles can never be separated : if we try to cut it then still both the poles will exist even ina small piece of magnet .it automatically develops the lost polarity

Magnet always develop certain area around it where its effect can be felt ie. magnetic field.  

MAGNETIC Field  

is studied by drawing imaginary lines called magnetic lines of forces.  

  Characteristics.  

• They always originate from North pole & terminate at South pole. This shows that if north pole was free is move it would have mvre towards south pole.  

•Place where they are closer indicate strong M. field i.e. at poles.  

•Mag. Field lines gives the direction of magnetic force.  

•Two magnetic lines will never intersect each other as they give direction of force & force can’t have 2 direction at a time.  

  •  M Field lines are closed continuous curves.  

This is what that happens in  magnetic materials .

Non magnetic materials

  • Magnetic forces 'act through' non-magnetic materials
  • These magnetic materials can be used as a shield around a magnet.
  • The domain theory of magnetism tries to explain why metals get magnetised
  • . The magnetic elements have little molecular magnets inside them.
  • Magnets attract only the magnetic materials

Types of magnetic materials

Soft magnetic materials (e.g. iron) have domains that easily move into line when the metal is placed in a magnetic field but as soon as the field is removed the domains take on a random pattern again. It returns to being unmagnetized straight away.

Hard magnetic materials (e.g. steel) have domains that do not easily move into line when the metal is placed in a magnetic field, a strong field is needed for some time, but then, when the field is removed the domains retain the magnetic pattern. The metal stays magnetic for a long time.

Which statement best describes how the period and frequency of electromagnetic waves change between gamma rays and microwaves?
Dimas [21]
On an electromagnetic spectrum, one of its noticeable trends is that the wavelength increases with decreasing energy and the wavelength decrease with increasing energy. Furthermore, gamma rays have high energy and short wavelengths while microwaves have low energy and long wavelengths.
