Are shark teeth valuable? Like all other fossils, shark’s teeth can be valuable, so they’re readily bought, sold and traded by enthusiasts and collectors. The most valuable of all is the tooth of the giant megalodon shark. Do shark teeth correct themselves? Sometimes shark teeth do not need to be treated, as the primary teeth […]
Is it ever grammatically correct to say me and?
Is it ever grammatically correct to say me and? In sentence a), Jenny and me/I are the subjects of the verb joined. Therefore, the subject pronoun, I, is considered correct. You will certainly hear native speakers say, “Jenny and me,” and it may be acceptable in spoken English, but most traditional grammarians and English teachers […]
How do you write a conclusion for a failed experiment?
How do you write a conclusion for a failed experiment? Method 1 of 5: Outlining Your Conclusion Restate: Restate the lab experiment by describing the assignment. Explain: Explain the purpose of the lab experiment. Results: Explain your results. Uncertainties: Account for uncertainties and errors. New: Discuss new questions or discoveries that emerged from the experiment. […]
What are period waves?
What is a posed question?
What is a posed question? To pose a question is to raise a question, to bring attention to a problem. It does not have to be directed to a specific person and cannot always be answered immediately. To ask a question is to inquire about something, often expecting a prompt answer from the person you […]
What does the slope represent in a velocity time graph?
What does the slope represent in a velocity time graph? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant. What is missing from a velocity time graph? position or distance. information missing from […]
What do you need to measure acceleration?
What do you need to measure acceleration? Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the […]
How can machine make work easier for you?
How can machine make work easier for you? There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied. The wheel and axle is a machine in which the wheel is […]
What are the factors that cause tectonic plate to move?
What are the factors that cause tectonic plate to move? Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. […]
Why does temperature decrease when volume decreases?
Why does temperature decrease when volume decreases? Because Boyle’s law states that pressure is inversely related to volume at a constant temperature. If you change volume, you change pressure, and then Charles’ Law no longer holds. That decrease in pressure then causes a decrease in temperature. So, gases cool as they expand. Why does temperature […]
