Your teacher is right. The moon can be seen early in the morning sometimes and late at night. Different phases are only visible on certain days as one day might be full quarter, the next full moon, the next first quarter, etc. 
        
             
        
        
        
Answer:Bohr placed the electrons in distinct energy levels.  Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits.
Explanation: also rutherfords was just a hypothesis while Bhor took the time to make his an experiment

Answer:
Explanation:
Let 100 m/s  be the velocity of projection. 
So horizontal component 
= 100 cos42 
= 74.31 m /s 
Vertical component = - 100 sin 42 . in upward direction
66.91 m/s 
Net displacement = 2.1 downwards ( + ve )
Using s = ut + 1/2 gt² 
2.1 = - 66.91 t  + .5 x 9.8 x t²
4.9 t² -  66.91 t - 2.1 = 0 
t = 13.685 s 
Horizontal distance covered 
= 13.685 x 74.31 
= 1016.93 m 
If angle of projction is 40°
So horizontal component 
= 100 cos40 
= 76.60 m /s 
Vertical component = - 100 sin 42 . in upward direction
64.27 m/s 
Net displacement = 2.1 downwards ( + ve )
Using s = ut + 1/2 gt² 
2.1 = -76.60 t  + .5 x 9.8 x t²
4.9 t² -  76.60 t - 2.1 = 0 
t = 15.659  s 
Horizontal distance covered 
= 15.659 x 76.60
= 1199.49  m 
So horizontal range is increased , if angle of projection is increased .
