Answer»

nA whole orange will float on water but peeled orange will sink in water. EXPLAIN?AnswerDrop an orange into water and it floats, but remove the peel from that same orange and it will sink. The unpeeled orange floats because the rind is very porous and FILLED with TINY pockets of air. Even though you're removing mass when you peel the orange, the peeled orange is more dense and SINKS in the water.

What is the use of polaroid in removing light from the glare and clear reflection of clouds? Explain​

Answer»

By now you can probably GUESS that Polaroid sunglasses cut the glare in reflected light because that light is POLARIZED. You can check this for yourself by holding Polaroid sunglasses in front of you and rotating them while looking at light reflected from WATER or glass.Uses of Polaroid:- (1) In motor car HEAD lights – To REMOVE headlight glare. (2) To improve color contrast in old oil paintings.

Magnitude of electric field intensity = 3 × 10³ N/CSide of the square = 10cm = 0.1mTo find : (a) The flux of this field through a square of 10 cm on a side whose plane is parallel to the yz plane. (B) The flux through the same square if the normal to its plane makes a 60° ANGLE with the X- axis.Solution :(a) The plane of square is parallel to the yz plane. So, angle between the plane and electric field is 0°Flux through the plane is given by,where,E DENOTES Electric field intensityA denotes area of squareby substituting all the given VALUES in the equation,Thus, the flux of this field through a square of 10 cm on a side whose plane is parallel to the yz plane is 30Nm²/C.(b) Here, the plane makes an angle of 60° with the x-axis so, the angle between them will be 60°Applying the same formula,thus, the flux through the same square if the normal to its plane makes a 60° angle with the x- axis is 15Nm²/C.

A wire of length 88cm and diameter 0.4mm has a resistance of 6ohm . calculate the specific resistance of the material of wire​

Answer»

The required SPECIFIC resistance of the wire​ is approximately 0.86 × 10⁻⁶ Ω-mExplanation:Given :length of the wire = 88 cmdiameter of the wire = 0.4 mmresistance of the wire = 6 ΩTo FIND :the specific resistance of the material of wireSolution :The resistance of a wire is given by,  whereρ denotes the specific resistancel denotes the LENGTHA denotes the AREA of cross SECTION⇒ length = 88 cmlength = 0.88 m⇒ diameter = 0.4 mmradius = 0.4/2 = 0.2 mmradius = 0.2 × 10⁻³ m⇒ Area of cross section = πr²Area = (22/7) × (0.2 × 10⁻³)²Area = (22/7) × 0.04 × 10⁻⁶Area =  0.88/7 × 10⁻⁶ m² Substitute the values, ∴ The specific resistance of the given wire​ is approximately 0.86 × 10⁻⁶ Ω-m
