Can a car run on jet fuel? Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Both are derived from crude oil, and both run their respective engines on combustion. How much […]
What is the structure and function of biomolecules?
What is the structure and function of biomolecules? Biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins. What […]
What is a quasi experiment example?
What is a quasi experiment example? This is the most common type of quasi-experimental design. Example: Nonequivalent groups design You hypothesize that a new after-school program will lead to higher grades. You choose two similar groups of children who attend different schools, one of which implements the new program while the other does not. Why […]
What is the value of 1 pico Farad?
What is the value of 1 pico Farad? 1/1,000,000,000,000 What is capacitance value? Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference (i.e., voltage) between them. The capacitance value of a capacitor is measured in farads (F), units named for English physicist Michael Faraday (1791–1867). A farad […]
Why is Shield 2p better than 2s?
Why is Shield 2p better than 2s? 2p has higher energy level because the negatively charged electron experiences less of an effective nuclear charge than the 2s electron. What happens to shielding when you go down a group? Down a group, the number of energy levels (n) increases, and so does the distance between the […]
What was the conclusion of the gold foil experiment?
What was the conclusion of the gold foil experiment? Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom. Why was gold foil used in Rutherford’s experiment? Rutherford used gold for his scattering experiment because […]
Why centrifugal force is called pseudo-force?
Why centrifugal force is called pseudo-force? The centrifugal force is a pseudo-force because if the centripetal force ceased for an object in circular motion, the centrifugal force the body is “feeling” would instantly disappear, and the object would travel tangentially to its line of motion. Can centrifugal force overcome gravity? The centrifugal force is real […]
At what altitude is 0 gravity?
At what altitude is 0 gravity? Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.) Which force is always attractive in nature? gravitational force Why gravity is not […]
What is hydraulic principle?
What is hydraulic principle? The basic principle behind any hydraulic system is very simple – pressure applied anywhere to a body of fluid causes a force to be transmitted equally in all directions, with the force acting at right angles to any surface in contact with the fluid. This is known as Pascal’s Law. What […]
