Answer:
v₂ = 48 mph
Explanation:
We know that,
Speed = distance/time
A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.
We need to find the speed to cover the same distance in 3 hours.
So, the new speed is 48 mph.
Answer:
Niels Bohr
Explanation:
Niels Bohr was scientist whose model showed electrons location around a nucleus and all in an orbit.The orbit had varying energies according to their sizes.This model further indicated that when an electron is lost or gained, radiation is absorbed or emitted.The modern atomic model was prepared from quantum mechanics which shows how matter differ in atomic and subatomic levels.In this model, the chances of finding an electron is higher where the cloud is more dense.Bohrs model resembles the electron cloud model is that they both talk about position of electrons in an atom, and the energy associated with size of the orbit occupied by the electron.
Its acceleration will change
