When a metal is illuminated with radiation with a wavelength of 152 nm, photoelectrons are ejected with a velocity of 7.9 x 105 m/s.
What is the work function, in eV, of the metal?
Explain the term 'work function' of a metal. The threshold frequency of a metal is f 0 . When the light of frequency 2f 0 is incident on the metal plate, the maximum velocity of e
Explain the working of a refrigerator A refrigerator is the reverse of a heat engine. Here the working substance extracts heat Q2 from the cold reservoir at temperature T2, som
Why we are showing work done over a closed path is zero to prove that electrostatic forces are conservative
Can you explain Poynting theorem?
What are the objectives of annealing? Slow cooling rate from the eutectoid temperature yields course pearlite - a mixture of relatively coarse crystals of ferrite and cementite
Ampere; A (after A.M. Ampere, 1775-1836) The basic SI unit of electric current, described as the current that, while going through two infinitely-long parallel conductors of ne
a closed organ pipe resonates with frequency 6hz and an open organ pipe resonates with frequency 12Hz. if the two organ pipes are joined to form a single organ pipe then it will re
VARIABLE OR NON-UNIFORM VELOCITY: If a body covers unequal displacement in most equal intervals of time, though the smallest interval may be, then the velocity of the body is s
We here at Brilliant assume that you work through these problems using some sort of writing utensil. Take your pen or pencil, balance it on its tip, and let go. It falls over. How
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
