What is an electromagnetic wave? Use the model to describe the characteristics of these waves.

Answers

Electromagnetic waves are the type of waves that do not need a medium to travel in. For example, the sun's rays travel in space toward earth without any medium

Electromagnetic radiation contains waves of the electromagnetic field, which propagate through space and carry radiant energy. The radiations coming from the sun are electromagnetic waves.

What are electromagnetic radiations?

Electromagnetic radiation possesses waves of the electromagnetic field, which travel via space and carry radiant energy. These waves include microwaves, radiowaves, infrared rays, visible light, UV rays, X- rays, and gamma rays.

Electromagnetic waves oscillate with the electric field and magnetic fields. Electromagnetic waves exhibit periodic changes in the electric field or magnetic field.

Depending on the periodic change in the waves that take place and the power produced in the waves, different wavelengths or frequencies of the electromagnetic spectrum are produced.

The effects of this radiation on chemical compounds and biological organisms are related to the power of the radiation and its frequency.

In order of increasing frequency and decreasing wavelength, electromagnetic waves are organized in the electromagnetic spectrum.

A bat wing is more similar in anatomical structure to a cat forelimb than to a bird wing. Answer the following questions about these structures.

Which pairs are homologous structures?

Which pairs are analogous structures?

Based on this, do you think a bat is more closely related to a cat or a bird? Explain your answer.

Answers

Answer: Which pairs are homologous - structures? The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale, In short term it is having the same relative position, value, or structure

Which pairs are analogous structures? - Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Also in short term it means comparable in certain respects, typically in a way which makes clearer the nature of the things compared.

Explanation: I do believe cats since bats actually belong to the super-order Pegasoferae, which contains horses, cats and dogs, cows, whales and hedgehogs.

A.Which pairs are homologous structures?

B.Which pairs are analogous structures?

C.Based on this, do you think a bat is more closely related to a cat or a bird? Explain your answer.

Answers

Answer:

The answer is homologous structures .

Explanation:

All the fore limbs that you mention are made up of same sets of bones. These vertebrates are all mammals, hence evolved from a common ancestral stock. So they all inherited a basic anatomical structure which later became adapted for different habits and habitats. These are regarded as homologous structures: anatomically similar, functionally different

Scientists conducted an experiment to show whether the ability to see an object affects a person's idea of the mass of the object. They used the following procedure: Obtain two cardboard boxes of different sizes. Place rocks in each box so that both boxes have the same mass. Close each box and tie a string to it so that participants lift each box using the string. Blindfold half of the participants in the experiment. Ask participants to lift each box using the string and report which one they think has more mass. Record results. The table shows the results of the experiment

Answers

Answer: Visual information makes them think the larger box has more mass.

An object is floating in the water, as shown in the picture below.

Describe the movement of the floating object as a wave passes by, and explain why the object is not carried forward with each wave.

Your answer should include at least two complete sentences.

Answers

Answer:

Balance Weight

Explanation:

The object has vertical weight with a floating device in it. When the waves hit the object in the water, they will go upward and then downward but stay in the original spot. This happens because the object uses the electromagnetic energy from the waves to not move with it.

To explain the electromagnetic spectrum , formula used is E=hcυ which indicates that all the factors in the formula are in direct proportion with each other.

What is electromagnetic spectrum?

The electromagnetic spectrum consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The spectrum is composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

3.) A student moves the end of a compressed coiled spring up and down to demonstrate wave motion. She then moves the compressed coiled spring faster but keeps everything else the same. Which characteristic will increase?

A.) wavelength
B.) frequency
C.) amplitude
D.) crest

Answers

Answer:

first answer is B second answer is a and third answer is d

Compared to wave A, wave B has a shorter wavelength and lower frequency. So, the correct options of 1, 2 and 3 are B, A and D.

What is Wave?

A wave is defined as a propagating dynamic disturbance of one or more quantities that may be periodic, in which case those quantities oscillate repeatedly about an equilibrium value at some frequency.

Frequency and wavelength can be calculated by this formula,

[tex]v=\lambda f\\v = velocity\\\lambda = wavelength\\f = frequency[/tex]

A wave with a crest that is closer to the baseline has a smaller amplitude. When compressed coiled spring faster but keeps everything else the same, the crest will increase.

Thus, the correct options of 1, 2 and 3 are B, A and D.
