What are the limitations of Ohms Law?
what is resistivity ? and what is resistance ? differentiate between the two..
a given wire of resistance 1ohm is stretched to double its length. what will be its new resiastance ?how to solve
Can you please explain Fleming's left hand rule and right hand rule and also teach me how to apply them?
A uniform metre scale balances horizontally on a knife edge placed at the 58 cm mark when a mass of 20g is suspended from one end.
(i) Draw a diagram of the arrangement and (ii) Find mass of the metre scale.
A hydroelectric power station takes its wat)er from a lake whose water level is 50 m above the turbine. Assuming an overall efficiency of 40%, calculate the mass of water which must flow through the turbine each second to produce power output of 1MW. (g=10 m/s2)
What are the factors affecting the angle of deviation ?
Name a material used for making a standard resistor. Give a reason, why it is used?
name the factors on which heat energy absorbed by a body depends and state how does it depend on them...................
what is meant by "heat is an additive quantity"
Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
A uniform metre rule of mass 100g is balanced on a fulcrum at mark 40 cm by suspending an unknown mass m at the mark 20 cm . Find the value of m .To which side the rule will tilt if the mass m is moved to the mark 10 cm ? What is the resultant moment now ? How can it be balanced by another mass 50 g?
how to find the angle of emergence in a prism?
how to find polarity of a solenoid by clock rule as when i look at its ends i m unable to distinguish which is clockwise and which is anticlockwise direction of current plzz tell me how to find the direction of current ???
A wire has a resistance of 10 ohm.it is stretched by 1/10 of its original length.then what is its resistance?answer soon
