Q: What can be thought of as the capacity a device has for storing charge? Read this paragraph and choose the correct option from the provided answers: The amount of charge, , held by each plate is given by where again is the voltage difference between the plates and is the capacitance of the plate configuration. Capacitance can be thought of as the capacity a device has for storing charge . In the parallel plate case the capacitance is given by where is the area of the plates, is the distance between the plates, and is the permittivity of free space whose value is . Choices: - potential - velocity - resonance - capacitance A:
capacitance

Q: What causes acid rain, ozone depletion, and global warming? Read this paragraph and choose the correct option from the provided answers: Air pollution consists of chemical substances and particles released into the air, mainly by human actions. The major cause of outdoor air pollution is the burning of fossil fuels. Indoor air can also be polluted. Air pollution, in turn, causes acid rain, ozone depletion, and global warming. Choices: - ozone layer - water pollution - radiation - air pollution A:
(Answer)
air pollution

Ques: Q: What term is used to describe a bond formed by the overlap of orbitals in an end-to-end fashion, with the electron density concentrated between the nuclei of the bonding atoms? Read this paragraph and choose the correct option from the provided answers: It is necessary to distinguish between the two types of covalent bonds in a C 2 H 4 molecule. A sigma bond ( bond) is a bond formed by the overlap of orbitals in an end-to-end fashion, with the electron density concentrated between the nuclei of the bonding atoms. A pi bond ( bond) is a bond formed by the overlap of orbitals in a side-by-side fashion, with the electron density concentrated above and below the plane of the nuclei of the bonding atoms. Figure below shows the two types of bonding in C 2 H 4 . The sp 2 hybrid orbitals are orange and the p z orbital is green. Three sigma bonds are formed by each carbon atom with its hybrid orbitals. The pi bond is the "second" bond of the double bond between the carbon atoms and is shown as an elongated blue lobe that extends both above and below the plane of the molecule, which contains the six atoms and all of the sigma bonds. Choices: - beta bond - lattice bond - rna bond - sigma bond A:
Ans: sigma bond

Q: A multiaxial ball-and-socket joint has much more mobility than a what hinge joint? Read this paragraph and choose the correct option from the provided answers: 9.6 | Anatomy of Selected Synovial Joints By the end of this section, you will be able to: Describe the bones that articulate together to form selected synovial joints Discuss the movements available at each joint Describe the structures that support and prevent excess movements at each joint Each synovial joint of the body is specialized to perform certain movements. The movements that are allowed are determined by the structural classification for each joint. For example, a multiaxial ball-and-socket joint has much more mobility than a uniaxial hinge joint. However, the ligaments and muscles that support a joint may place restrictions on the total range of motion available. Thus, the ball-and-socket joint of the shoulder has little in the way of ligament support, which gives the shoulder a very large range of motion. In contrast, movements at the hip joint are restricted by strong ligaments, which reduce its range of motion but confer stability during standing and weight bearing. This section will examine the anatomy of selected synovial joints of the body. Anatomical names for most joints are derived from the names of the bones that articulate at that joint, although some joints, such as the elbow, hip, and knee joints are exceptions to this general naming scheme. Choices: - triaxial - biaxial - quadaxial - uniaxial A:
(A).
uniaxial

Ques:Q: The pull of the moon's gravity on earth is the main cause of what water phenomenon? Read this paragraph and choose the correct option from the provided answers: The figure below shows why tides occur ( Figure below ). The main cause of tides is the pull of the Moon's gravity on Earth. The pull is greatest on whatever is closest to the Moon. Although the gravity pulls the land, only the water can move. As a result:. Choices: - storms - floods - waves - tides A:

Ans:tides

Q: What is the term for gases that absorb heat in the atmosphere? Read this paragraph and choose the correct option from the provided answers: Gases that absorb heat in the atmosphere are called greenhouse gases . They include carbon dioxide and water vapor. Human actions have increased the levels of greenhouse gases in the atmosphere. This is shown in Figure below . The added gases have caused a greater greenhouse effect. How do you think this affects Earth's temperature?. Choices: - ionic gases - thermal gases - sulfuric gases - greenhouse gases A:
greenhouse gases
