Answer:
the stove energy went into heating water is 837.2 kJ.
Explanation:
given,
mass of water = 2000 grams
initial temperature = 0° C
Final temperature = 100° C
specific heat of water (c) = 4.186 joule/gram 
energy = m c Δ T                            
             = 2000 × 4.186 × (100° - 0°)
             = 837200 J                          
              = 837.2 kJ             
hence, the stove energy went into heating water is 837.2 kJ.
 
 
        
             
        
        
        
The magnitude of the resultant force is given by the centripetal force, since the car is under a circular motion. So, we have:

The centripetal acceleration is given by:

Where v is the linear speed and r the radius of the circular motion. Replacing this and solving:

Mass of the block = 1.4 kg
Weight of the block = mg = 1.4 × 9.8 = 13.72 N
Normal force from the surface (N) = 13.72 N
Acceleration = 1.25 m/s^2
Let the coefficient of kinetic friction be μ
Friction force = μN
F(net) = ma 
μmg = ma
μg = a
μ = 
μ = 
μ = 0.1275 
Hence, the coefficient of kinetic friction is: μ = 0.1275
