What happens when warm air rises? (5 points) (will give brain)
a
Global temperature decreases.
b
The movement creates a difference in air pressure.
c
Cool air rises with it.
d
It moves towards the poles.
Answer:
b)
movement creates a difference in air pressure.
as warm air rises up it creates a vaccum so due to that the pressure in that region decreases.
Answer:
B. The movement creates a difference in air pressure.

Jessica is visiting a park with her mother. Jessica sits on a swing. Her mother pulls the swing to a height of 3 meters above the ground and lets it go. The image shows Jessica at three positions on the swing. Jessica‘s mass is 44 kilograms and the maximum velocity of the swing is 5 meters/second. What’s the energy she has at each position shown? Ignore friction and air resistance.

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

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
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

Which is a characteristic of an amorphous solid?
has a distinct melting point
becomes softer as temperature rises
particles arranged in a repeating pattern
made up of crystals
Answer:
4. Becomes softer as temperature rises
Explanation:
An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.

1st Law - Law of Inertia 2nd Law - Law of Force and Acceleration 3rd Law - Law of Action-Reaction An eagle soars through the air by pressing its wings downward. The air, in turn, propels the bird upward.
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.

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.
