Make a list of solids liquids and gases from your surroundings these substance classify them into solutions colloids and suspensions in information in english Project work |
|
Answer» ution is a homogeneous mixture of two or more components. The dissolution agent is solvent. The decomposed SUBSTANCE is solute. Components of the solution are atoms, ions, or molecules, making them small in 10-9 meters or diameter.Examples: sugar and waterSalt and waterSuspensionThe particles are larger in suspension found in the solution.Components of a suspension can be distributed equally by mechanical MEANS, such as shaking materials, but components will get settled.Examples: Oil and WaterMercury in oil in MercuryOil shaken in waterdust in airAir suitColloidThe particles can be mixed in size between PEOPLE found in solution and suspension so that they are distributed equally without dealing. These particles are in size of 10-8 to 10-6 meters and they are called colloidal particles or colodeae. The mixture made by them is called colloidal dispersion. The COLLOID consists in the medium that spreads in a colloidal dispersal.Example: milk• fog• Insecticide spray• cloud• Smoke• Dust• Mayonnaise• lotion• Gelatin• Butter• Jelly• Ink• Rubber• Liquid soap to wash clothes• Shampooi hope it helps uh ✌️✌️✌️ |

Give the meaning of the term 'soil erosion' ? |
|
Answer» e here is ur answer@@ brainlist pls @@In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved MATERIAL from one location on the Earth's crust, and then transports it to another location (not to be confused with weathering which INVOLVES no movement).In other words @@@@@When things erode, they wear away due to some force acting on them. Just look at any coastline, and you will notice how the constant pounding force from wind and waves causes erosion of the rocky structures, leaving behind all kinds of interesting cliffs, CAVES and structures. Soil is not immune to erosion, and like rocks along a coastline, soil can erode due to the effects of forces, such as water, wind and farming practices. In this lesson, we will learn about soil erosion and the factors that cause it. Soil is naturally created when SMALL pieces of weathered rocks and minerals mix with organic materials from decaying PLANTS and animals. Soil creation is a slow process, taking many years. However, the soil that is created is constantly subjected to natural and manmade forces that disrupt it. Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. Therefore, this is the layer that farmers want to protect for growing their crops and ranchers want to protect for growing grasses for their cattle to graze on. |

A clock with a metallic pendulum gains 5 sec each day at a temperature of 15 degree celcious and loses 10 sec each day at a temperature of 30 degree celcious. Find the coeff of thermal expansion of the pendulum metal |
|
Answer» we have to use MAINLY three CONCEPTS which are L2=L1(1+(alpha)(change in temprature)) another is binomial THEOREM which is (1 + x )n= 1 + nx for x and the last one which is T = 2\pi\sqrt{\frac{l}{g}} now it is given that clock is 5 seconds fast each day i.e. 1.16 \times 10-4 seconds i.e. time period at that temprature is (2 – 1.16 \times 10-4) and let at \theta temprature it shows correct time i.e. it’s time period is 2 seconds now, \frac{T_{1}}{T_{o}}=\sqrt{\frac{L_{1}}{L_{o}}} and L1 = Lo(1 + \alpha(15 – \theta)) \Rightarrow \frac{T_{1}}{T_{o}}=\sqrt{\frac{L_{o}(1 + \alpha (15 - \theta ))}{L_{o}}} using binomial theorem \Rightarrow \frac{T_{1}}{T_{o}}=1 - \frac{1}{2}\alpha(15 - \theta ) \frac{2 - 1.16 \times 10^{-4}}{2} = 1 + \frac{1}{2}\alpha (\theta - 15) \theta - 15 = \frac{1.16 \times 10^{-4}}{\alpha} …......................1 similarly 30 - \theta = \frac{2.32 \times 10^{-4}}{\alpha} …............................2 now SUBTRACTING adding equation 1 and 2 we get 15 = \frac{3.48 \times 10^{-4}}{\alpha} \Rightarrow \alpha = \frac{3.48 \times 10^{-4}}{15} substituting it in equation 1 we get \theta - 15 = 5 \Rightarrow \theta = 20 so clock will give correct time at 20 oC |

EXPLAIN PHRASES OF MOON |
| Answer» BRAINLIST and FOLLOW meThe phases of the Moon are the DIFFERENT ways the Moon looks from EARTH over about a month.As the Moon orbits AROUND the Earth, the half of the Moon that faces the Sun will be lit up. The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon. Each phase repeats itself every 29.5 days.The same half of the Moon always faces the Earth, because of tidal locking. So the phases will always occur over the same half of the Moon's surface.A phase is an angle of the moon to the earth so it appears differently every day. | |

plz answer... derive activity to understand the blue colour of sky and radish appearance of Sun at the time of sunrise and sunset list the various steps of activity draw the diagram for it and explain your observations |
|
Answer» E ✌✌✌Place a source of light S such as an ELECTRIC bulb at the focus of a converging lens L1. This lens provides a parallel beam of light.Allow the light beam to pass through a transparent glass beaker B of capacity 500 mL.After passing through the beaker containing about 400 mL of water allow the light beam to pass through a circular hole made in cardboard C. Obtain a sharp image of the hole on a screen MN using another convex lens L2.Dissolve about 200 g of sodium thiosulphate (hypo) in water taken in the beaker B. Add about 1 to 2 mL of concentrated sulphuric ACID with the help of an injection syringe dropwise in the beaker containing hypo solution.What do you observe?You will notice fine microscopic sulphur particles precipitating in about 2 to 3 seconds. As the sulphur particles begin to form, you can observe the blue light from the sides of the beaker. This is due to scattering of short wavelengths by minute colloidal sulphur particles. Observe the colour of the light patch on the screen. It is interesting to observe the change in colour of the patch-from orange red colour in the beginning to bright CRIMSON red colour later on the screen.This activity demonstrates the scattering phenomena of light that helps us to understand the bluish colour of the sky in general and the REDDISH appearance of the sun at the sunrise or the sunset.^_^^_^ HOPE IT HELPS ^_^^_^ |
