The regular reflection takes place when the light RAYS are incident on a polished smooth SURFACE like a plane mirror, a STAINLESS steel sheet and a thin sheet of aluminum, so, the reflected rays of light MOVE only in a fixed direction

An intensive property is a bulk property, meaning that it is a local physical property of a system that does not depend on the system SIZE or the AMOUNT of material in the system. Examples of intensive PROPERTIES include TEMPERATURE, T; refractive INDEX, n; density, ρ; and hardness of an object, η.

According to the de BROGLIE relation, electrons with kinetic energy of 54 eV have a wavelength of 0.167 nm. ... DAVISSON and GERMER's ACCIDENTAL discovery of the diffraction of electrons was the first direct evidence confirming de Broglie's hypothesis that particles can have wave properties as WELL.

Mass of hot water, m 1 =500gMass of cold water, m 2 =300gTemp. of hot water, t 1 =100 o CTemp. of cold water, t 2 =30 o CSp. heat of water, C=4.2Jg −1 o C −1 Let temp. of mixture be t o C. Then, Heat gained by cold water=m 2 ×C×(t−t 2 )According to the PRINCIPLE of CALORIMETRY, Heat lost = Heat gained500×4.2×(100−t)=300×4.2×(t−30)⇒5(100−t)=3(t−30)⇒−3t−5t=−90−500⇒−8t=−590⇒t= 8590 =73.8 o CSo, the final temperature of the mixture is 73.8 o C.

What's the QUESTION not UNDERSTOOD

Explanation:Spring balance is USED to measure the weight of the body whereas beam balance is used to measure the mass of the body. Since the mass of the body remains the same on earth as well as on moon but the acceleration due to GRAVITY differs. So, the beam balance GIVES the same value of mass of body on earth and moon but spring balance gives different values of weight. So we can measure the mass of body on moon by beam balance and then MULTIPLY it by g=9.8 m/s  2  to GET the weight which would be more accurate.

Explanation:START by DIVIDING the numerator by the denominator using long or SYNTHETIC division. enter image source here Thus: ∫ 2 0 x 2 − 2 x + 1 d x = ∫ 2 0 x − 1 + − 1 x + 1 d x We can INTEGRATE using the rules  ∫ ( 1 x ) d x = ln | x | + C and

a) Area of CONTACT Pressure=Force/Area EXPLANATION- More the area LESS the pressure Less the area more the presuureHence, Presuure is indirectly PROPORTIONAL to Area.Therefore, Pressure depends on the area of contact

tion:Opposites attract. To explain why magnets repel each other, a north end of a magnetic will be attracted to the south of ANOTHER magnetic. The north and north ends of two magnets as well as the south and south ends of two magnets will repel one another.The law states that the force of ATTRACTION or REPULSION between two magnetic poles is DIRECTLY proportional to the product of the strengths of the poles and INVERSELY proportional to the square of the distance between them.

aExplanation:SINCE Time for Two way is 2.3 secstherefore for SINGLE way = 1.5secSpeed = 1490m/sDist = Speed*time = 1490*2.3 = 3427Since the 2(Distance) = 3427                 (Since SONAR goes from ship to BOTTOM and then to Ship)Therefore D = 3427/2 = 1713.5 meterHence OPTION (a) = 1700m

:Amplitude of motion = AWE have to find displacement of simple harmonic oscillator from MEAN POSITION at where kinetic energy of oscillator becomes one-fourth of the total energy★ P.E. at displacement x from the mean position,U = 1/2 kx²★ K.E. at displacement x from the mean position,K = 1/2 k (A² - x²)★ Total energy at any pointE = K + U = 1/2 kA²where A denotes amplitudeLet p be the point at where kinetic energy becomes one-fourth of the total energy.➠ E/4 = K➠ 1/2 kA² = 4 × [1/2 k (A² - x²)]➠ A² = 4A² - 4x²➠ 4x² = 3A²➠ x² = 3A²/4➠ x = √3A/2∴ (B) is the correct answer.

An electrical supply SYSTEM has three main components, the generating stations, the TRANSMISSION LINES and DISTRIBUTION systems.

As seen from the SIDE of the approaching magnet the current inside the coil should be clockwise so that the induced magnetic pole on the left side of the coil is 'south' and it tends to REPEL the approaching magnet(Lenze's LAW), hence the magnet's FIELD inside the coil POINTS from right to left(opposite to the ...
