Answer:C:Less than 45 centimeters, as the ball transforms some of its potential energy into thermal energy and sound energy
Less than 45 centimeters, as the ball transforms some of its potential energy into thermal energy and sound energy.
Although the initial energy (potential energy is preserved), the energy of deformation as the ball strikes a surface creates energy dissipation in the form of frictional heat and audible sound energy.
Every time the ball bounces, its height will be less than its previous height.

Answer:
2240.92365 m/s 
Explanation:
 = Mass of electron =
 = Mass of electron = 
 = Speed of electron =
 = Speed of electron = 
 = Neutrino has a momentum =
 = Neutrino has a momentum = 
M = total mass = 
In the x axis as the momentum is conserved

In the y axis

The resultant velocity is

The recoil speed of the nucleus is 2240.92365 m/s
 
        
             
        
        
        
Answer:
V = 10 km / 1 hr = 10 km/hr
V = -10 j km / hr   if one were to use i, j, k as unit vectors with the usual orientation

Answer:
Explanation:
On both sides of the film , the mediums have lower refractive index. 
for interfering pattern from above , for constructive interference of reflected wave from both sides of the film , the condition is 
2μt = ( 2n +1 ) λ / 2 
μ is refractive index of film ,t is thickness of film λ is wavelength of light 
n is order of fringe 
for minimum thickness 
n = 0 
2μt =  λ / 2
t =  λ / 4μ
= 670 / 1.75 x 4
= 95.71 nm .
