Answer the following question given this paragraph: Particles that are composed of three quarks are called baryons . The two best known baryons are protons and neutrons. A proton is composed of two up quarks and one down quark (uud). The charge on the proton is the result of adding the charges on these quarks . Neutrons are composed of one up quark and two down quarks (udd). The charge on the neutron is the result of adding the charges on these quarks . Q: What are the two best known baryons? Choices: - flux and neurons - electrons and neutrons - shafts and neutrons - protons and neutrons A:
(Answer)
protons and neutrons

three
Ques:Answer the following question given this paragraph: As the fast-moving cold air mass keeps advancing, so does the cold front. Cold fronts often bring sudden changes in the weather. There may be a thin line of storms right at the front that moves as it moves. In the spring and summer, the storms may be thunderstorms and tornadoes. In the late fall and winter, the storms may bring snow. After a cold front passes, the cold air mass behind it brings cooler temperatures. The air is likely to be less humid as well. Can you explain why?. Q: What type of fronts often bring sudden changes in the weather, including different types of precipitation, depending on the season? Choices: - stationary fronts - occluded fronts - warm fronts - cold fronts A:

Ans:cold fronts
Ques:Answer the following question given this paragraph: Mid-wavelength electromagnetic waves are called light. Light consists of visible, infrared, and ultraviolet light. Humans can see only visible light. Infrared light has longer wavelengths than visible light and is perceived as warmth. Ultraviolet light has shorter wavelengths than visible light and has enough energy to kill bacteria. It can also harm the skin. Q: What type of light has shorter wavelengths than visible light and has enough energy to kill bacteria? Choices: - luminescence - infrared - reflected light - ultraviolet A:

Ans:
ultraviolet
