Answer:
Answer explained below
Explanation:
(a) The rays are diverging near the lens. They change the direction when they passed through the converging lens
(b) If the light rays don't bend they will move away from the optical (principal axis) as the other waves are moving.
(c) If we decrease the distance between lens and light source, most of the rays diverge and no ray converges on the screen even after passing through the lens. Here is a screenshot.

Answer:
Hi,
The correct answer option is; D. Most of the current will flow through one part of the circuit.
Explanation:
A short circuit is a low resistance path in an electric connection between two conductors supplying current in a circuit.
It happens when excess amounts of current flow in the power source through a 'short path'.
Short circuits occur at very high temperatures which is of course caused by the heat produced during dissipation.
An example of application of short circuit is arc welding, where heating is achieved through short circuit.
 
        
             
        
        
        
Hydraulic conductivity (K) is a property of soil<span> that describes the ease with which water can move through </span>pore<span> spaces. It depends on the permeability of the material (</span>pores, compaction) and on the degree of saturation. Saturated hydraulic conductivity, Ksat<span>, describes water movement through saturated media.</span><span />
        
             
        
        
        
Answer:
Given:
Thermal Kinetic Energy of an electron, 
 = Boltzmann's constant
 = Boltzmann's constant
Temperature, T = 1800 K
Solution:
Now, to calculate the de-Broglie wavelength of the electron,  :
:

 (1)
              (1)
where
h = Planck's constant = 
 = momentum of an electron
 = momentum of an electron
 = velocity of an electron
 = velocity of an electron
 = mass of electon
 = mass of electon
Now,
Kinetic energy of an electron = thermal kinetic energy



 (2)
                    (2)
Using eqn (2) in (1):

Now, to calculate the de-Broglie wavelength of proton,  :
:

 (3)
                             (3)
where
 = mass of proton
 = mass of proton
 = velocity of an proton
 = velocity of an proton
Now,
Kinetic energy of a proton = thermal kinetic energy



 (4)
                               (4)                    
Using eqn (4) in (3):
