Why is Earth tilted at 23.5 degrees and wobble? Its axis is tilted about 98 degrees, so its north pole is nearly on its equator. Astronomers suspect that this extreme tilt was caused by a collision with an Earth-sized planet billions of years ago, soon after Uranus formed. Earth’s axis appears stable, but it actually […]

How much water can be held in a tank? Storage tanks are labeled according to their “shell” size. But their actual water storage capacity is usually about 30% of that. So a 20 gallon tank really holds about 6 gallons of water. The rest of that space, about 70%, holds air. How much water can […]

What is the function of theory in research? Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounding assumptions. The theoretical framework introduces and describes the theory that explains why the research problem under study exists. What is the function […]

Which of the following is an example of the Doppler effect? An example of the Doppler effect is when a police car moves past a person who is standing still. As the police car moves towards them, the pitch of the police car’s siren goes up because the sound waves get closer together in front […]

What are some examples of conclusions? Sentence #1: restate the thesis by making the same point with other words (paraphrase). ~ Example: Thesis: “Dogs are better pets than cats.” […]

What 3 things does thermal energy depend on? The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object’s molecules (states of matter). The more molecules an object has at a given temperature, […]

Is chlorine trifluoride illegal? Though it was easily produced, only about 30-tons were ever produced. The chemical’s instability and reactive properties made it incredibly dangerous to handle. Fortunately, since the war, the compound has been banned under the Chemical Weapons Convention. What is the most common use for most of the lightweight organic compounds? Answer. […]
