I have learnt that when we push an object on a horizontal plane with a certain angle, we are increasing its normal reaction and therefore friction increases. Whereas if we pull it, friction decreases. Is that true? Yes, there is more friction if you push down, at an angle, ...

I am having some difficulties to identify compounds using their HNMR spectra. Can someone help me please. Thank you. This is tricky if you would like us to refer to spectra as this is a text only site. If you want help interpreting a particular spectrum you will need to ...

Physics Again!!
Am sending the same question coz i can't find the first one on the message boards. So plz help me. 1. 'velocity is a vector quantity, and the kinetic energy of a body is equal to half its mass times the square of its velocity, so kinetic energy must also be a vector.&#...

the dimensions of torque are the same as those of energy. Why it would nevertheless be inappropriate to measure torque in joules. Energy is force x distance, where distance is the distance in the direction of force. Torque is force x distance perpenduclar to force. Joules is a...

The emf induced across the wing-tips of a flying aircraft is of the order of several millivolts. Can this value be obtained using a sensitive millivoltmeter connected across the wing-tips? Explain your answer. Not if connections are actually made to the wing tips. The wires to...

Organic Chemistry
Hi, can you please help me with these questions. Methane and chlorine react when irradiated with UV light. Explain why the reaction requires only a little flash of UV light rather than prolonged radiation. Explain each of these observations as fully as you can. 1.

Using the first law of thermodynamics explain why the specific latent heat of vaporisation of water is greater than the specific latent heat of fusion of ice. The first law of thermodynamics (conservation of energy) has nothing to do with why vaporization requires more energy ...
