Answer the following question given this paragraph: Gravity near the Earth pulls an object downwards toward the surface of the Earth with an acceleration of . In the absence of air resistance, all objects will fall with the same acceleration. The letter is used as the symbol for the acceleration of gravity. When talking about an object's acceleration, whether it is due to gravity or not, the acceleration of gravity is sometimes used as a unit of measurement where . So an object accelerating at 2g's is accelerating at or. Q: What force pulls object downwards to the earth? Choices: - momentum - kinetic energy - motion - gravity A:
gravity

Answer the following question given this paragraph: When a capacitor is placed in a circuit, current does not actually travel across it. Rather, equal and opposite charge begins to build up on opposite sides of the capacitor --- mimicking a current --- until the electric field in the capacitor creates a potential difference across it that balances the voltage drop across any parallel resistors or the voltage source itself (if there are no resistors in parallel with the capacitor). The ratio of charge on a capacitor to potential difference across it is called capacitance. Q: What is the ratio of charge on a capacitor to potential difference across it called? Choices: - velocity - electromagnetism - resonance - capacitance A:
(Answer)
capacitance
Ques: Answer the following question given this paragraph: Bones become increasingly ossified and grow larger during fetal development, childhood, and adolescence. When skeletal maturity is reached at about age 20, no additional growth in bone length can occur. Q: At what age is skeletal maturity reached by humans? Choices: - 40 - 30 - 15 - 20 A:
Ans: 20

Answer the following question given this paragraph: The valence shell is the outermost occupied shell of electrons in an atom. This shell holds the valence electrons, which are the electrons that are involved in bonding and shown in a Lewis structure. Valence-shell electron pair repulsion theory , or VSEPR theory, states that a molecule will adjust its shape so that the valence electron pairs stay as far apart from each other as possible. This makes sense, based on the fact that negatively charged electrons repel one another. We will systematically classify molecules according to the number of bonding pairs of electrons and the number of nonbonding or lone pairs around the central atom. For the purposes of the VSEPR model, a double or triple bond is no different in terms of repulsion than a single bond. We will begin by examining molecules in which the central atom does not have any lone pairs. Q: What is the outermost occupied shell of electrons in an atom. Choices: - Inner Shell - radiative shell - modular shell - valence shell A:
(A).
valence shell
Ques:Answer the following question given this paragraph: A nuclear fusion reaction is so named because the nuclei (center) of atoms fuse (join) together in the process. In stars like our Sun, hydrogen atoms join together to create a helium atom. Nuclear fusion reactions need a lot of energy to get started. Once they begin, they produce even more energy. ( Figure below ). Q: In stars like our sun, hydrogen atoms join together to create what? Choices: - water molecule - oxygen atom - iron atom - helium atom A:

Ans:helium atom
Ques:Answer the following question given this paragraph: Temperature is a measure of the average kinetic energy of molecules. Consider a mixture of hydrogen and oxygen gas at a certain temperature. Use the formula for kinetic energy to explain why the hydrogen molecules move faster than the oxygen molecules. Then explain why there's no hydrogen in the earth's atmosphere, and why the moon has no atmosphere at all. Q: What property is a measure of the average kinetic energy of molecules? Choices: - mass - velocity - density - temperature A:

Ans:
temperature
