Is Probeware an electronic tool? Probeware is a learning tool that connects probes and sensors to a computer running suitable software and allows students to view real-time data in a variety of formats. When placed in an inquiry-based learning context, this capacity can significantly increase speed learning. Which best describes technology’s use in science? The […]
Why is Group 17 so reactive?
Why is Group 17 so reactive? The halogens are located on the left of the noble gases on the periodic table. Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups. What are the 3 groups […]
What is photosynthesis answer in one line?
What is photosynthesis answer in one line? Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules. […]
What are four things that indicate that a chemical change probably happened?
What are four things that indicate that a chemical change probably happened? There are five signs of a chemical change: Color Change. Production of an odor. Change of Temperature. Evolution of a gas (formation of bubbles) Precipitate (formation of a solid) What chemical is used in hot packs? Instant Hot and Cold Packs Commercial instant […]
What are the factors affecting the height of the waves?
What are the factors affecting the height of the waves? Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or […]
What temperature does water boil at 100 psi?
What temperature does water boil at 100 psi? Absolute pressure Water boiling point [bara] [1×105*Pa] [psia] [°F] 6.619 96.0 325 6.757 98.0 326 6.895 100 328 Does water boil at higher pressure? A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at […]
Is pitch and note the same?
Which location has the greatest number of hours of daylight?
Which location has the greatest number of hours of daylight? According to records from weather stations across the US, Yuma in Arizona is the sunniest place in the world. During daylight hours, which range from 11 hours in winter to 13 in summer, it has a 90% possibility of sunshine. What angle does the sun […]
What is the minimum energy of harmonic oscillator?
What is the minimum energy of harmonic oscillator? Classically, the lowest energy available to an oscillator is zero, which means the momentum also is zero, and the oscillator is not moving. Compare the quantum mechanical harmonic oscillator to the classical harmonic oscillator at v=1 and v=50. On what factor does the angular frequency of simple […]
How many years ago did the Rocky Mountains first form?
How many years ago did the Rocky Mountains first form? 1.7 billion years Where did Appalachian settlers come from? Many scholars trace the roots of Appalachian dialect—and southern highland culture in general—to migrants from northern Britain, and especially to the Scotch-Irish who came to the American backcountry from Ulster in the years preceding the American […]
