Answer:
The energy and the wavelength of the photon are 1.546 MeV and 
.
Explanation:
Given that,
Kinetic energy = 261 KeV
Planck's constant 
Speed of light 
Mass of electron 
Charge 
(A). We need to calculate the energy of the photon
Using formula of rest mass energy
Energy in eV
The total energy of photon
(B). We need to calculate the wavelength of the photon
Using formula of wavelength
Put the value into the formula
Hence, The energy and the wavelength of the photon are 1.546 MeV and .
Planet Geos in orbit a distance of 1 A.U. (astronomical unit) from the star Astra has an orbital period of 1 "year." If planet Logos is 4 A.U. from Astra, how long does Logos require for a complete orbit?
TB = <span>8</span> years
Answer:
The atomic model, the structure of the solar system, and the theory of black holes are examples of models created using indirect evidence.
Explanation:
I have no explanation sorry.
In a projectile, the horizontal acceleration is zero. The velocity remains constant at all times. However, the <u>vertical acceleration</u> is -9.81m/s^2.
Hope this helps!
