This question is about the Earth's atmosphere and light/sound waves.
Explain the relationship between wavelength and frequency in the electromagnetic spectrum.
Answer:
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength
Explanation:
The wavelength and frequency of an electromagnetic wave are inversely proportional to each other.
What is Wavelength and frequency?Wavelength is the distance between any two identical points or adjacent crests in the adjacent cycles of a waveform signal which is propagated in space or along a wire. In the wireless systems, this length is usually specified in the units of meters (m), centimeters (cm) or millimeters (mm).
Frequency is the rate at which the current changes its direction per second time. Frequency is measured in the units of hertz (Hz), an international unit of measure where, 1 hertz is equal to 1 cycle per second of time.
The wavelength in an electromagnetic spectrum is inversely proportional to the frequency of the wave. The shorter the wavelength, the higher the frequency of the wave. Because, all light waves move at the same speed in a vacuum medium, the number of wave crests passing at a given spot in one second is determined by the wavelength of the wave.

View the photo below, read the passage, and answer the question.
The arcs in the photo are background galaxies that were distorted and magnified by a giant cluster of dark matter. As the light leaves its source, the gravity of the cluster of dark matter bends that light, creating the swoops in the image above.
This passage best supports which conclusion about dark matter?
a. Dark matter does not give off light, but scientists can see the reflection in stars around it
b. Dark matter is created from clouds of dust and gas scattered throughout the universe
c. Dark matter has a significant impact on the stellar life cycle
d. Dark matter does not give off light, so it can only be detected by observing the effects of gravity on visible objects nearby

Does mass influence how quickly an object falls?
Claim:
Two Pieces of Evidence:
Reasoning:
Answer:
Both objects fall at the same speed. Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. ... The horizontal force applied does not affect the downward motion of the bullets -- only gravity and friction

Answer:hen a bird flies, its wings push in a down- ward and a backward direction. This pushes air downward and backward. By Newton's third law, the air pushes back on the bird in the opposite directions—upward and forward. This force keeps a bird in the air and propels it forward.

The electrical force exerted by a positive charge on a negative charge Magnetic attraction between two magnets
Which statement best explains why the table is incorrect?
Spring force is a force acting at a distance.
Electrical force is not a contact force.
Gravitational force can act between planets and sun only when they are in contact.
Magnetic attraction is a contact force
Speed force acting at a distance
Mintu wants to increase the heat transfer between a metal iron and another piece of metal he wants to shape. He decides to increase the time the two metals are in contact, use a larger metal iron, and use a new metal material with a higher specific heat.
Where is Mintu's error?
Mintu should have decreased the size of the metal iron.
Mintu should have decreased the time he touches the two metals.
Mintu should have chosen a material with a lower specific heat.
Mintu should have chosen a material the same temperature as the iron.

Identify at least one example each of absorption, transmission, reflection, and refraction of waves in this photograph.
Answer:
the answer above me is wrong, there is no rainbow.
Explanation:
"ABSORPTION WAVES: Water absorbs almost all the infrared energy from sunlight, so a possible answer for absorption is light absorption through water which will later on heat up the water.
TRANSMISSION WAVES: pool water waves passing a shallow area continue with their energy mostly unchanged.
REFLECTION WAVES: the surface of the water reflects light.
REFRACTION WAVES: waves will bend away from normal if the waves move from a denser medium to a less dense medium which applies to Snell’s law." - anonymous

A student is modeling electric forces and potential energy in a system with two opposite charges. For his model, he uses a rubber band with a marble attached to either end. When the rubber band is stretched, does the model predict what will happen to the force and potential energy in the system? Explain.
Answer:
the potential energy will increase
Explanation:
The model will predict an increase in both the potential energy and increase in force ( i.e. work done )
The increase in work done in a model of electric forces and potential energy is directly proportional to the increase in the potential energy as the stretched rubber band changes its position after it is stretched.
The model described in the question typically represent a transfer of energy from point A to point B in a system by doing work in a system ( i.e. stretching of the rubber band ).
Hence we can conclude that The model will predict an increase in both the potential energy and increase in force ( i.e. work done ).
