Answer: Bohr's model
Explanation:
The Bohr's model is also known as the solar system model which describe that an atoms are basically imagine in the form of solar system. The Bohr's model basically describe about the atoms that it consist of nucleus with the number of electron in an orbit by using the electrostatic attraction.
The Bohr's model are introduced for overcoming the drawback in the Rutherford model as he proposed an idea that at different energy levels the electron can revolve in certain orbits around nucleus.

Answer:
work done will be equal to 305.05 J
Explanation:
We have given force exerted F = 45 N
Angle with the horizontal
Distance moved due to exerted force d = 9.1 m
Work done is equal to , here F is force is angle with horizontal and d is distance moved due to force
So work done
So work done will be equal to 305.05 J
