Focal length is minimum and maximum when , five the formula plzzzzzzzzzzzzz say soonnnnnn |
|
Answer» It is not a measurement of the actual LENGTH of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm FILM at the focal plane in the CAMERA. The focal length of a lens is determined when the lens is focused at INFINITY. |

How does the force constant depend upon the mass of the load |
|
Answer» The spring CONSTANT is different for different elastic objects. For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension DOUBLES. This WORKS until the limit of proportionality is EXCEEDED. |

Explain the process of liquid transferred heat by Convection? |
|
Answer» CONVECTION: ... Convection occurs when WARMER areas of a liquid or gas rise to cooler areas in the liquid or gas. As this happens, cooler liquid or gas TAKES the PLACE of the warmer areas which have risen higher. This cycle RESULTS in a continous circulation pattern and HEAT is transfered to cooler areas. |

Calculate the point along the same line between the two charges where the net electric field will be zero. Formulas E=kq/r2 Attempt at Solving Well, I GET as far as setting E1=kq/r2 equal to E2=kq/r2 but am at LOST as to what to do next. I tried bringing the equations all to one SIDE and setting them equal to zero but can't seem to isolate for r. I ALSO tried cross multiplying and dividing but didn't get the answer from that either. I know the answer (0.661m left of the -3.00 charge) but am unable to find out how to get the answer. If someone COULD provide a detailed, comprehensive explanation |

State the principle of homogeneity of dimensions and check the below equation is dimensionally correct or not V=u+at |
|
Answer» es that the dimensions of each term on both the SIDES of EQUATION are same, then the physical quantity will be correct.Explanation:The principle of homogeneity is that the dimensions of each the terms of a dimensional equation on both sides are the same. any equation or FORMULAE involving dimensions (like mass, length, time, temperature, electricity) have the terms with same dimensions. V=u+atwhere u = initial velocity (m/s) v= final velocity (m/s) a = acceleration (m/) t= time takenL.h.s dimensions for v = []R.H.S dimension of u = [] dimension of at = []dimensions of v,u and at are same. so the equation v=u+at is dimensionally correct |
