Carl is making a model to demonstrate the reason Earth has seasons. He has a round lamp to represent the Sun. He drew the continents on a table tennis ball to represent Earth.
• What are two ways Earth needs to move in Carl’s model?
• How can Carl demonstrate Earth’s position relative to the Sun when it is summer in Australia?
Answer:
Explanation:
Earth needs to rotate by itself to represent its self rotation which gives us day and night. It also needs to rotate around to sun to give seasons.
Rotate ball so area marked Australia is closest to the round lamp.
Answer:
Explanation:
Earth i.e. tennis ball needs to move in circle around the Sun i.e. lamp. that gives seasons on earth. it also needs to rotate on its axis that is not perpendicular to its circle track around the Sun. that gives day and nite.
Aus in summer means tennis ball marked as Aus facing Sun with the ball's axis at an angle so that the area is closer to the Sun.

The speed of sound is the measure of how far it travels in a certain amount of time. The speed of sound will differ depending on which of the following?
-The frequency of the sound
-Where the sound originated from
-The pitch of the sound
-The material the sound is traveling through
Answer:
The material through which sound is travelling
Explanation:
Solid has compact molecules so sound waves can moove easily and fastly.
In case of liquid, it has relatively less inter- molecular space so, sound transfers slowly..
Hope you can generate meaning regarding spped of sound in gas...

The range of wavelengths present in the different types of electromagnetic radiation is called the electromagnetic spectrum. The electromagnetic spectrum is illustrated in the diagram provided. Different portions are labeled. Which portion has the longest wavelengths?
Answer: C is the answer
Explanation:
In the given diagram Portion C has the longest wavelengths.
What is the electromagnetic spectrum?The electromagnetic spectrum is the range of all types of electromagnetic radiation. Electromagnetic radiation is a form of energy that travels through space in the form of waves. This energy is produced by the movement of electric and magnetic fields, and it includes a range of wavelengths and frequencies.
The electromagnetic spectrum includes a wide variety of types of electromagnetic radiation, ranging from low-energy radio waves to high-energy gamma rays.
The different regions of the electromagnetic spectrum include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Each region of the electromagnetic spectrum has its own unique properties, such as its wavelength, frequency, and energy.
For example, radio waves have long wavelengths, low frequencies, and low energies, while gamma rays have short wavelengths, high frequencies, and high energies. The different types of electromagnetic radiation have different applications in areas such as communication, medicine, and astronomy.
Therefore, The correct option is portion C having the longest wavelengths.

Proper nutrition is needed to be a healthy person. Track how many calories you eat and how many calories you burn in a day. Select the Calorie Tracker to get started. Use the rubric to guide you.
(ion know how to keep track of calories and i hate try to do it so just make up some paragraph for me for this assignment please.)
Here, I hated PE too. Write down calories, and make up lame exercises to "burn them off" like running or swimming or dancing. Do it appropriately, sometimes you can't allways burn it off, like if you gained 100 calories and only burned 80. It's fine.
A rule of thumb is that about 100 calories per mile are burned for a 180-pound person and 65 calories per mile are burned for a 120-pound person. A 150-pound person will burn roughly 400 calories during an hour-long swim at a moderate pace and 700 at a vigorous one. The average person will burn 300-800 calories per hour dancing.
