Plzz answer ny question PLZZZ fast....

Answer»

al length will be 10 cm.    REASON :    when object is placed at 2F1 then the image is obtained at 2F2    in this case , u and v are equal in magnitude and opposite in sign   so by the data in the table , we can SAY that radius of curvature is 20 cm  , hence focal length will be 10 cm as it is half of the radius of curvature.(b) the sixth one is INCORRECT (u=-9 and v=+90)because in a CONVEX mirror , when an object is placed between the focus and the lens ... then the image is FORMED on the same side and is virtual .in this case , object is placed between focus and lens but the image is formed on the other side of the lens (bcause v = +ve) hence it is wrong

Explain the mechanism behind diamond rainfall on several planets

Answer»

rain sulfuric acid on Venus?Venus is the second planet from the Sun, and in many ways, it is just like Earth. It’s pretty similar in size, mass, composition and even proximity to the Sun. But that’s where the similarities end. The atmosphere of Venus is composed of carbon DIOXIDE, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Its atmosphere is extremely dense, and it’s estimated that the atmospheric mass is 93 times that of Earth’s atmosphere, whereas the pressure at the planet’s surface is about 92 times that at Earth’s surface. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere.The atmosphere on Venus is mostly made of Carbon Dioxide, with small quantities of sulfuric acid. Image via Daily Galaxy.The atmosphere on Venus is mostly made of Carbon Dioxide, with small quantities of sulfuric acid. Image via Daily Galaxy.Because CO2 is a greenhouse gas, the temperature on Venus is at least 462 °C – much higher than that of MERCURY, which is much closer to the Sun. The surface of Venus can be accurately described as hellish. Venus has clouds which may EXTEND from about 50 to 70 km; beneath the clouds, there is a layer of haze down to about 30 km and below that it is clear. Above the dense CO2 layer there are thick clouds consisting mainly of sulfur dioxide and sulfuric acid droplets.The thing is, there is no rainfall on the surface of Venus – while sulfuric acid rain falls in the upper atmosphere, it evaporates around 25 km above the surface. Also, sulfur dioxide concentrations in the atmosphere, which dropped by a factor of 10 between 1978 and 1986, which suggests that the sulfur in the atmosphere actually comes from volcanic eruptions. The clouds are also extremely acidic and there is also lightning on Venus. The sulphuric acid droplets can be highly electrically charged, and so they offer the potential for lightning. The European Space Agency has a mission (Venus Express) studying the clouds and atmosphere on VenusVerdict: It does rain sulfuric acid on Venus, but not on the surface, 25 km high in the atmosphere. The sulfur may come from volcanic eruptions.Does it rain Glass on HD 189733b?PHOTO: Turbulent alien world: An illustration depicting HD 189733b (AFP: ESA/NASA)HD 189733b is an extrasolar planet approximately 63 light-years away from the Solar System. The planet was discovered in 2005. With a mass 13% higher than that of Jupiter, HD 189733 b orbits its host star once every 2.2 days, making it a so-called hot Jupiter. Hot Jupiters are a class of extrasolar PLANETS whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close to their star.Diagram showing how a smaller object (such as an extrasolar planet) orbiting a larger object (such as a star) could produce changes in position and velocity of the latter as they orbit their common center of mass (red cross).The planet was discovered USING Doppler spectroscopy – an indirect .

How to make keiledoscope with foil paper?

Answer»

ls:paperconstruction paper (optional)card stockcrayons or markerspencilglue (we used model glue and glue sticks)tin foilplastic bagsglitter and sequinstapeInstructionsStart by decorating the paper however you desire with your CRAYONS or MARKERS. We stuck our decorated papers onto construction paper to MAKE them a bit sturdier.Stick some tinfoil onto the card stock, shiny side facing out.Make three folds(four sections) in your foil-covered cards. PUT glue along one side and fold the cards into "triangular tubes." Glue them shut and wait for them to dry.While the glue dries, cut little circles out of plastic bags. Put a strip of glue on one circle and drop glitter and/or sequins into the center. Then, drop the other plastic circle on top and let the whole thing dry. Now you have little pockets filled with glitter and sequins.Roll your decorated paper around your "triangular tube" and glue it down. (For younger kids, the project can end here if they get tired or distracted. For older kids—let's persevere!)Cut out black circles from the card stockand make a hole through the center with a pencil. Then fold the circle over one end of the tube and tape it on. (We lost patience with waiting for glue to dry—tape to the rescue!).Finally, tape a glitter and sequin "pocket"onto the other end of the tube.This is a great, MESMERIZING craft that won't get old with your kids!
