What is mechanical efficiency is the ratio of? Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one. What causes low volumetric efficiency? […]
Which of the following intermolecular forces is the strongest?
Which of the following intermolecular forces is the strongest? Ion-dipole forces What kinds of forces hold ionic solids together quizlet? What forces hold ionic solids together? Ionic bonds because ionic bonds are much stronger than any intermolecular forces. Ionic solids tend to have: Much higher melting points than molecular solids. What kind of force is […]
What color leaves absorb the maximum amount of light?
What color leaves absorb the maximum amount of light? green What colors are absorbed by the leaf? Through three layers of leaf material, only green is transmitted, indicating that both blue and red are absorbed. The most important plant pigment is chlorophyll-a, which exhibits a grass-green color, and absorbs light in the blue and red […]

In which of the following number all zeros are significant? Therefore, in 20.000, all zeros are significant. Do zeros count as decimal places? Leading zeros (zeros before non-zero numbers) are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, […]

How does pollution play a role in greenhouse effect?
How does pollution play a role in greenhouse effect? Some air pollutants cause the climate to warm. Greenhouse gases prevent some of that heat from leaving the atmosphere. The recent increase in greenhouse gas pollution is trapping excess heat and causing the climate to warm. Air pollution includes greenhouse gases such as carbon dioxide. What […]
Is sulfuric acid a binary compound?
Is sulfuric acid a binary compound? It is element stem + “ic acid” (or “ous acid”). This gives names like sulfuric acid and nitric acid. The “hydrogen name” is formed as if the substance were an ionic compound. So the name would be hydrogen sulfate, but that name is hardly ever used. Is hydrocyanic acid […]
Who described the shape of the earth?
Who described the shape of the earth? Isaac Newton What is an oval sphere called? prolate. A spheroid, or ellipsoid of revolution, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry. What is a globe? […]
What are the 3 types of body composition?
What are the 3 types of body composition? Most people are unique combinations of the three body types: ectomorph, mesomorph, and endomorph. Ectomorphs are long and lean, with little body fat, and little muscle. What do dead rows focus on? The dead row is the health fitness exercise which is performed to strengthen the muscles […]
How do daughter cells compare to parent cells?
How do daughter cells compare to parent cells? Daughter cells have roughly the same number of chromosomes as parent cells. They can be produced through either the process of mitosis or meiosis. Cell division is the process that creates daughter cells. It influences how cells replicate and reproduce themselves, along with the manner in which […]
