Q: What occurs when two waves combine and cancel each other out? Read this paragraph and choose the correct option from the provided answers: Destructive interference occurs when two waves combine and cancel each other out. This occurs when a peak in one wave lines up with a trough in the other wave. Choices: - terrible interference - primitive interference - molecular interference - destructive interference A:
destructive interference

Q: What are the three ways to classify matter based on how light interacts with it? Read this paragraph and choose the correct option from the provided answers: Light may interact with matter in several ways, including reflection, refraction, transmission, and absorption. Matter can be classified on the basis of how light interacts with it as transparent, translucent, or opaque. Choices: - opaque, invisible, visible - transitive, opaque, translucent - extensive , opaque , translucent - transparent, opaque, translucent A:
(Answer)
transparent, opaque, translucent

Ques: Q: All of the stages that a cell goes through make up what? Read this paragraph and choose the correct option from the provided answers: Cell division is just one of the stages that a cell goes through during its lifetime. All of the stages that a cell goes through make up the cell cycle . Choices: - glycolysis - cytokineses - photosynthesis - the cell cycle A:
Ans: the cell cycle

Q: Where does visible light fall in between on the electromagnetic spectrum? Read this paragraph and choose the correct option from the provided answers: The only light that people can see is called visible light . It refers to a very narrow range of wavelengths in the electromagnetic spectrum that falls between infrared light and ultraviolet light. Within the visible range, we see light of different wavelengths as different colors of light, from red light, which has the longest wavelength, to violet light, which has the shortest wavelength. You can see the spectrum of colors of visible light in Figure below . When all of the wavelengths are combined, as they are in sunlight, visible light appears white. You can learn more about visible light in the chapter "Visible Light" and at the URL below. Choices: - infrared light and specific light - infrared light and gamma ray - radio and infrared - infrared light and ultraviolet light A:
(A).
infrared light and ultraviolet light

Ques:Q: Space telescopes avoid such problems completely since they orbit outside the what? Read this paragraph and choose the correct option from the provided answers: Telescopes on Earth all have one big problem: Incoming light must pass through the atmosphere. This blocks some wavelengths of radiation. Also, motion in the atmosphere distorts light. You see this when you see stars twinkling in the night sky. Many observatories are built on high mountains. There is less air above the telescope, so there is less interference from the atmosphere. Space telescopes avoid such problems completely since they orbit outside the atmosphere. Choices: - ozone layer - galaxy - earth's crust - atmosphere A:

Ans:atmosphere

Q: When two electric contacts come together it completes a what? Read this paragraph and choose the correct option from the provided answers: Figure below shows a diagram of a simple doorbell. Like most doorbells, it has a button located by the front door. Pressing the button causes two electric contacts to come together and complete an electric circuit. In other words, the button is a switch. The circuit is also connected to a voltage source, an electromagnet, and the clapper of a bell. When current flows through the circuit, the electromagnet turns on, and its magnetic field attracts the clapper. This causes the clapper to hit the bell, making it ring. Because the clapper is part of the circuit, when it moves to strike the bell, it breaks the circuit. Without current flowing through the circuit, the electromagnet turns off. The clapper returns to its original position, which closes the circuit again and turns the electromagnet back on. The electromagnet again attracts the clapper, which hits the bell once more. This sequence of events keeps repeating as long as the button by the front door is being pressed. Choices: - charge - breaker - atom - cricuit A:
cricuit
