Answer:
The energy of these two photons would be the same as long as their frequencies are the same (same color, assuming that the two bulbs emit at only one wavelength.)
Explanation:
The energy  of a photon is proportional to its frequency
 of a photon is proportional to its frequency  . The constant of proportionality is Planck's Constant,
. The constant of proportionality is Planck's Constant,  . This proportionality is known as the Planck-Einstein Relation.
. This proportionality is known as the Planck-Einstein Relation.

The color of a beam of visible light depends on the frequency of the light. Assume that the two bulbs in this question each emits light of only one frequency (rather than a mix of light of different frequencies and colors.) Let  and
 and  denote the frequency of the light from each bulb.
 denote the frequency of the light from each bulb.
If the color of the red light from the two bulbs is the same, those two bulbs must emit light at the same frequency:  .
.
Thus, by the Planck-Einstein Relation, the energy of a photon from each bulb would also be the same:
 .
.
Note that among these two bulbs, the brighter one appears brighter soley because it emits more photons per unit area in unit time. While the energy of each photon stays the same, the bulb releases more energy by emitting more of these photons.

Answer:
B
Explanation:
A bicameral system describes a government that has a two-house legislative system, such as the House of Representatives and the Senate that make up the U.S. Congress.
 
        
             
        
        
        
Answer:
(a) 0.345 T
(b) 0.389 T
Solution:
As per the question:
Hall emf, 
Magnetic Field, B = 0.10 T
Hall emf, 
Now,
Drift velocity, 

Now, the expression for the electric field is given by:
 (1)
                            (1)
And

Thus eqn (1) becomes
 
 
where 
d = distance
 (2)
                      (2)
(a) When 

(b) When 

 
        
             
        
        
        
Ohm's Law states V = IR
So, 
I = V/R
The answer is B. 10/5=2 amps
