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.

the gene for the fur length trait has two alleles. The allele F is for short fur, and the allele fis
for long fur.
Marley, a dog from this group, has long fur. Marley has two alleles for long fur.
Based on this information, what is Marley's phenotype for the fur length trait?
FF
FI
short fur
long fur
Answer:
long fur
Explanation:
Phenotype refers to an individual's observable traits, such as height, eye color, and blood type ( the outside apperance ) so what is the dog's fur can be discribed as ? the answer is long fur

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

1. List at least two ways that you and your family currently limit the amount of energy that you use.
2. Then list at least five ways that you might further reduce your energy usage, even if it means some personal sacrifices.
Answer:
1. Turns lights off when not being actively used, and unplug devices, even when being turned off just being plugged in still drains electricity!!
2. Limit the use of electronic devices, limit the use of lighting unless necessary(?), Limit use of charging devices; meaning maybe don't leave them plugged in constantly, Limit amount of devices and/or devices used during a period of time.

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.
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.
A lamp has been on for several hours, and its lampshade begins to feel warm. What causes this to happen?
For this assignment, you will develop several models that show how light waves and mechanical waves
are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief
description of the interaction between the wave and the material. You will also compose two typewritten
paragraphs. The first will compare and contrast light waves interacting with different materials. The
second will explain why materials with certain properties are well suited for particular functions.

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.
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.
