If work function for certain metal is 1.8ev what is stopping potential for electrons ejected from metal when light of 4000angstrom minute shine on metal ? what is speed of electron​

Answer»

V= 1.3VExplanation:We know the RELATION hf = K max + Ø where photon energy is h F, k max is kinetic energy of the emitted electrons and WORK function is Ø.  4000 Angstrom = 400 nanometreSo K max = e VNow h f = e V + ØSo frequency of incident LIGHT is f = C / λh c / λ = e V + ØTo solve for stopping potential we get  h c / λ – eV = Ø  – e V = Ø – h c / λV = Ø / e – h c / e λ V = h c / e λ – Ø / eSubstituting the value we getV = 6.62 x 10^-34 x 2.99 x 10^8 / 1.602 x 10^-10 x 400 x 10^-9  - 1.8 V x e / e3.1 V – 1.8 VV = 1.3 V

A car moves a car covers distance S1 with velocity V1 and distance S2 with velocity V2 between two cities P and Q its average velocity will be?​

Answer»

A CAR covers distance s1 with velocity v1 and distance s2 with velocity v2 between two CITIES P and Q.To find :The AVERAGE velocity.Solution :Instantaneous speed of an object is equal to distance travelled per unit time by that object.So,(equation 1)wheres = Distance travelled andt = Time taken.For distance s1,velocity of car = v1,So, By equation 1,(equation 2)So, for covering distance s1, time taken:For covering distance s2, time taken:Average velocity of an object is equal to the ratio of TOTAL displacement travelled and total time taken.As,Total distance travelled in this journey = s1 + s2Total time taken in this journey = T1 + t2,So,Putting the values of time t1 and t2,we getAverage velocity :

What is the need to convert dynamo to alternating current ​

Answer»

At its simplest, it is basically a fixed switch connects and disconnects as the shaft TURNS. The COMMUTATOR constantly changes the polarity of the output current so that the output is always of the same polarity. WITHOUT a commutator, a dynamo would simply produce alternating current just LIKE an alternator.Explanation:

Answer»

aw.At a constant temperature the potential difference between two end points of a conductor is directly proportional to the current supplying through the conductor.V = IR (R is a conductor of variations).EXPERIMENTAL verification:- In ORDER to verify Ohm's Law we prepare an electric circuit. Ammeter is added in series and voltmeter in parallel. Then we supply current through the conductor and take reading of Ammeter and Voltmeter. Further, we find the value of I. We repeat this experiment five times supplying different amount of current and note the value of I. We observed that value of I/V always remains same in different experiments. If we draw a graph between I and V we get a STRAIGHT line. This PROVES that Current is directly proportional to the Potential difference. Thanks for the Question....
