A steel ball sinks in water but a glass ball floats in mercury. Both will float in........ (a) molten gold (b) molten platinum (c) molten uranium (d) molten copper |
Answer» Answer:a substance can float in another substance if the density of the former is less than the density of the former. “Float” is somewhat of a misleading term in these situations, because there are frequent interactions occurring between the ATOMS of one substance and the atoms of the other, but it’ll suffice for our purposes. Now, steel has a density of approximately 8.05 g/cubic centimeter. Many substances have densities GREATER than this. Examples are mercury, LEAD, and osmium, which have RESPECTIVE densities of 13.56, 11.34, and 22.59, all in the same units as the density above. Now, the exact density of glass is widely disputed, as it falls along a spectrum, or range. This is because glass can be created in several different ways, and the density of the final product depends on the densities of the individual starting products. However, it is common knowledge that steel is more dense than all forms of glass. Therefore, the glass ball will float in all of the substances named above. So, the steel and glass balls are both ABLE to float in mercury solutions, lead solutions, and especially osmium solutions (osmium is considered to be the densest substance in our universe). please mark me as brainliest

One litre of water at 40°C is mixed with one litre of water at 50°C. The temperature of the mixture will be: |
|
Answer» the temperature will SLIGHTLY less than 40°C. Explanation: Because WATER expands when heated, 1 litre of water at 50°C will have less mass than 1 litre of water at 30°C. As a RESULT, the 30°C litre has slightly more than the 50°C litre, and thus the average will end up slightly less than 40°C. Explanation: |

An object of size 7 cm is placed at a distance of 27 cm in front of a concavemirror of focal length 18 cm. Find position, nature and size of image formed |
|
Answer» Answer: Thus,we should place a screen at a distance of 54 cm on the same side as of object as to get sharp IMAGE. Thus,the height of image is 14cm and is inverted at a distance of 54cm for sharp image formation. Explanation: TO FIND: The nature and size of image formed also the distance from which mirror should be PLACED fro sharp image GIVEN: Object size=7cm Object distance[U]=27cm Focal length of CONCAVE mirror[F]=18cm Let V be the image distance So by mirror formula we know that; 1/f=1/V+1/U 1/(-18)=1/V+1/(-27) 1/V=1/(-18)+1/27 1/V= (-3+2)/54 1/V= -1/54 V=-54cm Thus,we should place a screen at a distance of 54 cm on the same side as of object as to get sharp image. The magnification is shown by: m=-V/U m=-(-54)/-27 m= -2 Magnification of image will be |2| and - shows the inverted nature of image m is also stated as m= height of image/height of object -2= height of image/7 height of image= -14cm Thus,the height of image is 14cm and is inverted at a distance of 54cm for sharp image formation. |
