All three have the same current, so that is not a factor. Wattage (power) is E*I or i^2 R. The higher the resistance, the more power dissipated. The answer is R3 because it has the highest resistance.
R3 <<<< ===== answer.
        
             
        
        
        
Answer:

Explanation:
given,
radius of curve = 166 m
angle of the banked road = 11°
mass of car = 736 Kg
speed of the curve = 81 km/h
                                 = 81 x 0.278 = 22.52 m/s
normal force acting on the tires
on tire there will be two force acting on it 
first one will be force acting due to weight and the other force acting on the tire is due to centripetal force.




 
        
             
        
        
        
Answer:
"It will be more than the speed of sound waves in air at 20*C and water at 20*C."
Explanation:
Speed of sound in a medium depends upon the density and elasticity of the medium.
If the elasticity of a medium is greater and the density of that medium is lower, sound will travel faster. Although density is also a factor but the major factor is Elasticity.
Hence, sound travel faster in solids than in liquids and even slower in gases due to elasticity difference.
                         
That is why the speed of sound in glass will be more than the speed of sound waves in air at 20*C and water at 20*C.
