Answer:
42 km/h was the average speed of the car for its three-hour trip.
Explanation:
Diameter of the car wheel = d = 0.4 m
Radius of the car wheel = r = 0.5 d = 0.5 × 0.4 m =0.2 m
Distance covered in 1 complete revolution = 
Distance covered in 100,000 complete revolution,D = 
1 m = 0.001 km
125,663.71 m = 125,663.71 × 0.001 km = 125.66371 km
Time taken to complete 100,000 revolution by a wheel = t = 3 hours
Speed of car : S
42 km/h was the average speed of the car for its three-hour trip.
Energy can be released and absorbed during the formation of a solution, not one or the other. When a solute interacts with the solvent, energy is absorbed so the solvent can overcome the intermolecular bonds of the solute and energy is released, most commonly, in the form of heat, light, or a gaseous byproduct.
The frequency produced by the string could be 437 Hz or it could be 443 Hz.
The frequency of the beats ... 3 Hz ... tells the piano tuner that
