Solution:Two experiments are used to demonstrate how light travels in straight LINES. In the FIRST example, the presenter arranges THREE PIECES of card, with holes in, in an uneven line. The light stops and cannot travel through all three cards. When she arranges the holes in a straight line, the light can travel through. In the second example, a light source is shone onto a SHINY and uneven surface. We see how the light still travels in a straight line, but scatters and reflects in different directions.Explanation:

Barometer, device used to MEASURE atmospheric pressure. Because atmospheric pressure changes with DISTANCE above or below sea level, a barometer can ALSO be used to measure altitude. There are two main types of barometers: MERCURY and aneroid.Explanation:HOPE it helps you!please mark me as a brainliest

Magnesium hydroxide ( Mg(OH)2 ) or MILK of magnesia.Sodium hydroxide (NAOH) or caustic SODA. CALCIUM hydroxide ( Ca(OH)2 ) or limewater.Explanation:

When substances made of iron are exposed to oxygen and moisture (water), rusting takes place. Rusting removes a layer of MATERIAL from the surface and makes the substance weak. Rusting is a chemical CHANGE. The process of DEPOSITING zinc on the iron to prevent rusting is known as galvanization. A striking example of the use of galvanization is the water pipes USED in HOUSES. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. A chemical change is also called a chemical reaction.

a disease caused by the LACK of an element in the DIET, usually a PARTICULAR VITAMIN or mineral.

An eclipse happens when a planet or a moon gets in the WAY of the Sun’s LIGHT. Here on Earth, we can experience two kinds of ECLIPSES: solar eclipses and lunar eclipses.A solar eclipse happens when the moon gets in the way of the sun’s light and casts its shadow on Earth. That MEANS during the day, the moon moves over the sun and it gets dark. Isn’t it strange that it gets dark in the middle of the day?This total eclipse happens about every year and a half somewhere on Earth. A partial eclipse, when the moon doesn’t completely cover the sun, happens at least TWICE a year somewhere on Earth.But not everyone experiences every solar eclipse. Getting a chance to see a total solar eclipse is rare. The moon’s shadow on Earth isn’t very big, so only a small portion of places on Earth will see it. You have to be on the sunny side of the planet when it happens. You also have to be in the path of the moon’s shadow.On average, the same spot on Earth only gets to see a solar eclipse for a few minutes about every 375 years!Explanation:

:1) The nail TURNED brown due to the deposition of COPPER on the nail.2) Copper Sulphate (blue) + Iron nail (silver) → Ferrous Sulphate (GREEN) + Copper (brown)3) Displacement reaction4) Iron is more reactive in the given reaction.Knowledge Bytes:→ Displacement Reaction:Displacement reaction is a chemical reaction in which a more reactive metal displaces a LESS reactive metal from its salt solution. The reactivity table is given below:Please refer attachment to VIEW the image.The most common displacement reaction is that of the copper sulphate with the iron nail where the more reactive metal iron, displaces copper from its salt solution.CuSO₄ + Fe → FeSO₄ + Cu

Flower are the REPRODUCTIVE part of the PLANTS Explanation:hope it's help uhplease MARK me as brainliest

please mark me as brainleastExplanation:Herbivores are animals whose PRIMARY food source is plant-based. EXAMPLES of herbivores include vertebrates like deer, KOALAS, and some bird SPECIES, as well as invertebrates such as crickets and caterpillars. These animals have evolved DIGESTIVE systems capable of digesting large amounts of plant material.

CNG burns cleaner when compared to traditional PETROL and diesel. Carbon monoxide emissions are reduced by roughly 80 percent, and 44 percent fewer hydrocarbons are produced in comparison to gasoline-powered vehicles. CNG cars also run QUIETER than gasoline and diesel vehicles, which RESULTS in LESS noise POLLUTION.

Herbivores form an important link in the food chain because they consume plants to DIGEST the carbohydrates PHOTOSYNTHETICALLY produced by a plant. Carnivores in TURN consume herbivores for the same reason, while omnivores can obtain their nutrients from either plants or ANIMALS.
