An atom. :) Good luck! The atom is the smallest particle in an element.
Answer:
The energy of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency
On the other hand, there is an inverse relation between the frequency and the wavelength :
(2)
Where is the speed of light, which is also a constant.
If we substitute (2) in (1) we will have the following:
(3)
This means, there is direct relation between the energy and the frequency and there is an inverse relation between the energy and the wavelength.
Answer:
Explanation:
Let the mass of the other car is "m" and its kinetic energy is
now the mass of the first car is two and half times and its kinetic energy is half that of other car
so we will have
now speed of both cars is increased by value of 9 m/s
so now we will have same kinetic energy for both cars
so speed of first car is
Can’t top the first answer so check that out. My boy is a legend.
