Answer:
Planck postulates that the energy exchanges between matter and radiation do not take place in continuous manner but by discrete and indivisible quantities or quanta of energy. He then shows that the quantum of energy must be proportional to the frequency ν of the radiation. (1.1) where h is known as the Planck’s constant.

Answer:
Explanation:
Given
radius of Planet is equal to radius of Earth
Weight of body on Planet
where m=mass of body
Weight of body on earth
acceleration due to gravity is given by
where G=gravitational constant
M=mass of Planet
r=radius of planet
for earth
for planet
substituting these values in and
divide 1 and 2
Answer:
23 cm
Explanation:
The formula for magnification is;
Magnification = image distance / object distance
use values as;
3.2 = v / 30 where v is image distance
v =30*3.2
v=96 cm
The relationship of the focal length with image distance and object distance is expressed as;
where f is the focal length and u is object distance
use values in the equation as;
f=160/7
f=22.86
f= 23 cm ----------nearest a cm
