Can we draw trajectory of point on a wheel rolling without slipping?Indicate the velocity vectors as well |
|
Answer» For many dynamics PROBLEMS, rolling without slipping means there is a friction force acting on the WHEEL at the contact point P. Thisfriction force prevents slipping. In this instance the friction is known as static frictionsince there is no relative sliding between the wheel and surface at the contact point P.

Answer in one word: 1. What are the small pores on the under surface of the leaves called?2.What is the mode of nutrition in fungi ?3.where does the bacterium Rhizobium live? |
|
Answer» Answer: 1) Stomata are tiny pores present on the undersurface of the LEAVES. They help in the exchange of gases in plants. Plants take up carbon dioxide from the atmospheric air and release oxygen and water vapour into the atmosphere through the stomata. 2) Nutrition. Fungi get their nutrition by absorbing organic compounds from the environment. Fungi are heterotrophic: they rely solely on carbon OBTAINED from other organisms for their metabolism and nutrition. 3) Rhizobia are special bacteria that can live in the soil or in nodules formed on the roots of legumes. In root nodules, they FORM a symbiotic association with the legume, OBTAINING nutrients from the PLANT and producing nitrogen in a process called biological nitrogen fixation, or BNF. |

Answer» ANSWER:Sedimentation, Decantation and Filtration Sometimes, it may not be possible to separate components of a mixture by winnowing and handpicking. For example, there may be lighter impurities like dust or soil particles in rice or pulses. How are such impurities separated from rice or pulses before cooking? Rice or pulses are usually washed before cooking. When you ADD water to these, the impurities like dust and soil particles get separated. These impurities go into water, which becomes a little muddy. Now, what will sink to the bottom of the vessel — rice or dust? Why? Have you seen that the vessel is tilted to pour out the DIRTY water? When the heavier component in a mixture settles after water is added to it, the process is called sedimentation. When the water (along with the dust) is removed, the process is called decantation. (Fig.1) Let us find a few other mixtures that can be separated through sedimentation and decantation. The same principle is used for separating a mixture of two liquids that do not mix with each other. For example, oil and water from their mixture can be separated by this process. If a mixture of such liquids is ALLOWED to stand for some time, they FORM two separate layers. The component that forms the top layer can then be separated by decantation. Let us again consider a mixure of a solid and liquid. After preparing tea, what do you do to remove the tea leaves? Try decantation. It helps a little. But, do you still get a few leaves in your tea? Now, pour the tea through a strainer. |

Answer» Answer:a) First, we write the chemical reaction and we CALCULATE the relative molecular mass (or atomic mass if it's an element) of each SUBSTANCE in the reaction: PbO2 + 4 HCl → PbCl2 + Cl2 + 2 H2O PbO2 Mm = 1 · 207,2 + 2 · 16,0 = 239,2 u ( 1 ) HCl Mm = 1 · 1,0 + 1 · 35,5 = 36,5 u PbCl2 Mm= 1 · 207,2 + 2 · 35,5 = 278,2 u Cl2 Mm= 2 · 35,5 = 71,0 u H2O Mm= 1 · 1,0 + 2 · 16,0 = 18,0 u Mm 239,2 36,5 278,2 71,0 18,0 PbO2 + 4 HCl → PbCl2 Cl2 2 H2O b) Second, we calculate the amount of substance (n) with the given data in the statement. n = 31,2 g PbO2 · 1 mol PbO2 / 239,2 g PbO2 = 0,130 moles PbO2 c) Third, we balance the chemical equation. Chemical reaction: PbO2 + 4 HCl → PbCl2 + Cl2 + 2 H2O Pb 1 1 Cl 2 2 4 H 4 1 O 2 2 The equation is already balanced. PbO2 + 4 HCl → PbCl2 + Cl2 + 2 H2O d) Then, we collect all the information: Mm 239,2 36,5 278,2 71,0 18,0 Stoichiometry 1 mol 4 moles 1 mol 1 mol 2 moles PbO2 + 4 HCl → PbCl2 Cl2 2 H2O Amount of substance 0,130 moles x moles y moles z moles t moles 1 unified atomic mass unit, symbol (u) e) Fourth, we calculate the amount of the substances (n) in the chemical reaction: x moles HCl = 0,130 moles PbO2 · 4 mol HCl / 1 mol PbO2 = 0,520 moles HCl y moles PbCl2 = 0,130 moles PbO2 · 1 mol PbCl2 / 1 mol PbO2 = 0,130 moles PbCl2 z moles Cl2 = 0,130 moles PbO2 · 1 mol Cl2 / 1 mol PbO2 = 0,130 moles Cl2 t moles H2O = 0,130 moles PbO2 · 2 moles H2O / 1 mol PbO2 = 0,260 moles H2O f) We collect the information again: Mm 239,2 36,5 278,2 71,0 18,0 Stoichiometry 1 mol 4 moles 1 mol 1 mol 2 moles PbO2 + 4 HCl → PbCl2 Cl2 2 H2O Amount of substance 0,130 moles 0,520 moles 0,130 moles 0,130 moles 0,260 moles g) Then, we can answer the questions in the statement by USING the amounts of substances: What mass of lead dichloride would be obtained from 37,2 g of PbO2? (step e) There will be produced 0,130 moles PbCl2 The mass is: 0,130 moles PbCl2 · 278,2 g PbCl2 /1 mol PbCl2 = 36,17 g PbCl2 What mass of CHLORINE gas would be produced? (step e) There will be produced 0,130 moles Cl2 The mass is: 0,130 moles Cl2 · 71,0 g Cl2 /1 mol Cl2 = 9,23 g Cl2 |
