Answer: chemical → kinetic → electrical → light
Explanation: At the same time when the generator lights up the bicycle lamp the lamp lights up using electrical energy so mechanical energy is also transformed into electrical energy.
 
        
             
        
        
        
Answer:
   k_max = 31.82 w/mk
   k_min  = 17.70 w/mk
Explanation:
a) the maximum thermal conductivity is given as

where k_m is thermal conductvitiy of metal
k_p is thermal conductvitiy of carbide
v_m = proportion of metal in the cement = 0.17
v_p = proportion of carbide in the cement = 0.83
             = 66*0.17 + 28*0.83
            k_max = 31.82 w/mk
b) the minimum thermal conductivity is given as

           = \frac{28+66}{28*0.17 +66*0.83}
         k_min  = 17.70 w/mk
 
        
             
        
        
        
Light is faster. Humans can travel faster than sound, however not light- nothing seems to go faster than 3×10∧8 meters per second.
        
             
        
        
        
Answer:
The spacing between the planes of the crystal is 0.295 nm
Explanation:
Given:
λ = wavelength = 0.24 nm
θ = angle of incidence = 66°
The spacing d between the planes of the crystal is equal:
