Answer:
SULPHUR + OXYGEN =PLEASE ANSWER❤❤❤❤❤❤ State a characteristic property of a density of a substance Two metals A and B have work function 4 eV and 10 eV respectively.which have higher threshold wavelength A block of mass m as shown in figure The angle of elevation of the top of a tower from two points a and b lying on the horizontal Surface tensionof a liquid is 80dyne/cm in c.G.S. System it may be expressed in m.K.S system as State the necessity of control of output voltage of an inverter Son of elevation of the top of a tower from a point 20 metre away from the base is 45 degree the height of the tower is A point charge Q is placed at the origin. Find the electrostatic energy stored outside the sphere of radius R centred at the origin. Two capacitors of capacitances 4⋅0 µF and 6⋅0 µF are connected in series with a battery of 20 V. Find the energy supplied by the battery.
Angle of the axis of analyser with beam is π/6
• when electric feild E of unpolarized light passes through polarizer then the intensity of polarized light is reduced
•According to Malus law ,
The intensitt of transmitted light from the analyser when completely plane polarized light is incident , is directly proportional to square of cosine angle between line of analyser and plane polarized light
•i.e. I = I• cos²A
I = 3(I•)/4
3(I•)/4 = I• cos²A
cos²A = 3/4
cos A = √3/2
A = π/6
•angle of the axis of analyser with beam is π/6
