A jet plane is travelling towards West at a speed of 1800 km/h. What is the voltage difference developed between the end of the wing having a span of 25 m, if the earth's magnetic field at the location has a magnitude of 5xx10^(-4) T and the dip angle is 30^(@) ?

The freezing point depression of 0.1 molal solution of acetic acid in benzene is 0.256 K kg mol^(-1) .Kf for benzene is 5.12 K kg Mol^(-1) . What conclusion can you draw about the molecular state of acetic acid in benzene.

Explain, Stability of a crystal is reflected in the magnitude of its melting point, comment. Collect melting points of solid water, ethyl alcohol, diethyl ether and methane from data book. What can you say about the intermolecular forces between these molecules?

A 50 MHz sky wave takes 4.04 ms to reach a receiver via retransmission from a satellite 600 km above the earth.s surface. Assuming retransmission time by satellite negligible, find the distance between source and receiver. If communication between the two was to be done by Line of Sight (LOS) method, what should size and placement fo receiving and transmitting antennas be?

How can you distinguish between primary, secondary and tertiary alcohols by oxidation method? Write the principle of manufacture of ethyl alcohol from starchy materials. How can you prepare (i) ethyl alcohol from methyl alcohol (ii) methyl alcohol from ethyl alcohol.

A person can focus objects only when they lie between 0.5m and 3m from his eyes. What spectacles should he use to increase his maximum distance of distinct vision to infinity?

What is the area of the plates of a 2 F parallel plate capacitor, given that the separation between the plates is 0 . 5 cm, ?(you will realise from your answer why ordinary capacitors are in the range of mu F or less. However, electrolytic capacitors do have a much large capacitance (0.1 F) because of very minimum separation between the conductors )

A man with normal near point (25 cm) reads a book with small print using a magnifying glass: a thin convex lens of focal length 5 cm. (i) What is the closest and the farthest distance at which he should keep the lens from the page, so that he can read the book when viewing through the magnifying glass? (ii) What is the maximum and the minimum angular magnification (magnifying power) possible using the above simple microscope?
