Write the Dimension of a/b in the relation F=a√x +bt² |
| Answer» Hello friend,f = a√x + bt2, where f = (M L T\xa0−2(, x = (L) and t = (T).f = a√x = bt2f = a√x(M L T\xa0−2)\xa0= (a L½)= (a) = (M L½\xa0T\xa0−2)F = (bt2)(M L T\xa0−2)\xa0= (b T2)= (b) = (M L T−4)(a)/(b) = (M L½\xa0T\xa0−2)/(M L T−4)\xa0= (M0\xa0L−½\xa0T2)So, (a/b) = (M0\xa0L−½\xa0T2)Hope it helps!!! | |

What is gravition |
| Answer» movement, or a tendency to move, towards a centre of gravity, as in the falling of bodies to the earth.<br>Every object in the universe attracts every other object with a force which is called the force of\xa0gravitation.Gravitation is one of the four classes of interactions found in nature.These are(i) the gravitational force(ii) the electromagnetic force(iii) the strong nuclear force (also called the hadronic force).(iv) the weak nuclear forces.Although, of negligible importance in the interactions of elementary particles, gravity is of primary importance in the interactions of objects. It is gravity that holds the universe together. | |

Define 1 candela |
| Answer» That\'s it<br>Thank you yogita<br>In the field of physics, the Candela (often denoted by the symbol ‘cd’) can be defined as the unit of luminous intensity – a measure of the wavelength weighted power emitted by a source of light. As per the International System of Units (often abbreviated to SI), the Candela is a base unit which can be defined by taking the fixed value (in numerical terms) of the luminous efficacy of the monochromatic radiation having a frequency of 540 * 1012 Hertz. Alternately, it can be described as the luminous power corresponding to one unit solid angle that is emitted by a point source of light (in a given direction). The SI base unit for luminous intensity has Latin roots – the word ‘candela’ translates to ‘candle’ in the Latin language. It can be noted that the luminous intensity associated with the light emitted by a common wax candle is roughly equal to one candela. | |

Why are rain drops spherical? |
| Answer» Yeah you are a genius!!!<br>Rain drops are not spherical they are hemispherical like a paper weight because of the force of air from the bottom . To know more search factomania sony BBC earth water drop shape on YouTube<br>This answer is perfect and understandable. Thank you.<br>We all know that for a given volume of a liquid, a sphere has the least surface area. Also, the more the surface area of an object, the more is its surface energy.\xa0Now, to remain in stable equilibrium, a body always tries to minimize its surface energy. Therefore it tries to reduce its surface area and hence acquires a spherical shape.\xa0All this phenomena is because of the presence of surface tension of a fluid.\xa0 | |
