Waves
What are 3 different kinds of waves? (name any 3)
Water waves, sound waves, light waves, radio waves, microwaves, infrared waves, ultraviolet waves, X-rays, gamma rays, seismic waves (earthquake waves), and depending on their motion, transverse and longitudinal.
What is the difference between a solar eclipse and a lunar eclipse?
A solar eclipse occurs when the Moon passes between the Sun and Earth, causing the Moon to cast a shadow on Earth. A lunar eclipse occurs when Earth is between the Sun and the Moon, causing Earth to cast a shadow on the Moon.
What is the smallest planet in the Solar System?
Mercury.
What is gravity?
The force that attracts a body toward the center of the earth, or toward any other physical body having mass.
What happens when you add Mentos into a bottle of Coke?
The Coke shoots out of the bottle like a volcano!
What is the difference between longitudinal waves and transverse waves?
A longitudinal wave is a wave where the particles of the medium vibrate parallel to the direction of the wave propagation, while a transverse wave has particles vibrating perpendicular to the direction of wave propagation; essentially, in a longitudinal wave, the movement is back and forth in the same direction as the wave, whereas in a transverse wave, the movement is up and down relative to the wave direction.
What is it called when you can see every part of the Moon the Sun's light is shining on?
A Full Moon.
What is the biggest planet in the Solar System?
Jupiter.
What does gravity do for the Solar System?
In the solar system, gravity acts as the primary force that keeps planets, moons, asteroids, and comets in orbit around the Sun, essentially holding the entire solar system together by pulling all objects towards the most massive body, which is the Sun; this gravitational pull determines the path and speed of each celestial body in its orbit.
Oxygen!
What are the 3 types of wave behaviors?
What is it called when the Moon looks completely dark?
A New Moon.
What is the closest planet to the Sun?
Mercury.
Do mass and distance affect gravity?
Yes!
What is the largest organ in the human body?
The skin!
What is older, analog or digital signals?
Analog technology is older than digital technology.
What way is the Earth tilting during summer?
During summer in the Northern Hemisphere, the Earth is tilted towards the sun; meaning the North Pole is tilted closer to the sun, causing longer daylight hours and warmer temperatures.
What is the farthest planet away from the Sun?
Neptune.
How does mass affect gravity?
Mass directly affects gravity, meaning that the more mass an object has, the stronger its gravitational pull will be, essentially, the greater the mass, the greater the gravitational force exerted on other objects around it.
What is the process of water turning into a vapor called?
Evaporation!
What is the difference between analog and digital signals?
Analog signals were/are used for things like radios, VHS tapes, walk mans, etc.
Digital signals were/are used for things like TV's, phones, tablets, etc.
During winter, the Earth is tilted away from the sun. This means that when the Northern Hemisphere experiences winter, the North Pole is tilted away from the sun, while the Southern Hemisphere is tilted towards the sun.
Which planet is most like the Sun and why?
Jupiter is often considered the closest due to its similar composition, primarily consisting of hydrogen and helium, just like the Sun, and because it captured a large amount of the leftover material from the solar system's formation, making it the largest planet in our solar system; however, it is not massive enough to ignite nuclear fusion like the Sun does.
How does distance affect gravity?
Distance affects gravity by weakening it; the further apart two objects are, the weaker the gravitational pull between them, as gravity is inversely proportional to the square of the distance between them.
What is the hottest planet in our Solar System?
Venus!
