How are types of energy in the electromagnetic spectrum defined?
Drupady [299]
It is defined by their wavelength. Different colors have different wavelengths. For example, radio waves have a really long wavelength, whereas gamma-rays have a very short wavelength.

How are the oscillating magnetic and electric fields of an electromagnetic wave positioned relative to each other?​
Pepsi [2]

Answer:

Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

7 types of electromagnetic waves from lowest to highest frequency
goldfiish [28.3K]

Answer:

radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

Explanation:

Electromagnetic waves are the waves which are created as the result of the electrical waves which are perpendicular to each other and also perpendicular to the direction of propagation.

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.

In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:  

<u>radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays</u>.

Two blocks, with masses M2&gt;M1, are connected by ropes. You pull to the right on a second rope, with external force "T1".The b
Gre4nikov [31]

Answer:

(M_1 + M_2) a > M_2 a

Becuase M_1 +M_2> M_2

So then we can conclude that:

T_1 > T_2

And that makes sense since the force T_1 needs to accelerate the two masses and T_2 just need to accelerate M_2.

So the best option for this case would be:

a. T1 > T2

See explanation below.

Explanation:

For this case we consider the system as shown on the figure attached.

Since the system is connected the acceleration for both masses are equal, that is a_{M_1}= a_{M_2} = a

From the second Law of Newthon we have that the force applied for the mass M_2 is F_{M_2}= M_2 a and we know that the force acting on the x axis for the mass 2 is F_{M_2}= T_2 so then we have that T_2= M_2 a

Now when we consider the system of M_1 +M_2 as a whole mass, this system have the same acceleration a and on this case we will see that the only force acting on the entire system would be T_1 and then by the second law of Newton we have that:

F_{M_1 +M_2} = T_1 = (M_1 +M_2) a

And then if we compare T_1 and T_2 we see that :

(M_1 + M_2) a > M_2 a

Becuase M_1 +M_2> M_2

So then we can conclude that:

T_1 > T_2

And that makes sense since the force T_1 needs to accelerate the two masses and T_2 just need to accelerate M_2.

So the best option for this case would be:

a. T1 > T2

How does secondary succession help restore equilibrium to a region destroyed by a flood?
I am Lyosha [343]

Answer:

Explanation:

Ecological succession is a process of inhabiting a zoological area by a group of organisms. it involves many stages to reach the climax stage such as primary, secondary, tertiary names basing on the habitat where it occurs. once the organisms reach the most stable stage of the succession. thus it maintains equilibrium Succession helps restore the equilibrium of an ecosystem by forming up new species, diversifying species, and basically by replacing the damaged, deranged, or disturbed community. For instance, when a sudden climate change occurred in a community, such as drought, dryness, fire, or heat waves, all living things that depends on water or survives in a cool, wet environment will die or migrate somewhere else. Thus, leaving that community vacant and/or unoccupied by any living things. Succession, then, will take place in that area by going through various stages until reaching the climax stage, in which the ecosystem is complete again.
