As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. Equation to follow are F = mv²/r "Force of friction" Ff= μsN, Normal N=mg Ff=μsmg. Therfore
mv²/r = μsmg cancel mass "m" The formula to follow will be μs = v²/rg
μs = v²/rg μs = (28.89 m/s²)²/ (65 m)(9.8 m/s²) = 1.31
Answer:
A. friction is greatly reduced.
Explanation:
Maglev train runs on the principle of repulsion force due to magnetic field
here we know that magnetic field will apply force on the train which helps to levitate train in air
This is why it runs forward due to other component of magnetic force and hence it can run with high speed in air with least friction as there is no two surfaces in contact with each other
So here we can say that
Train run with very high speed due to least value of friction between two surfaces which moves relative to each other
so correct answer is
A. friction is greatly reduced.
The two elements are in the same period, with Element R the first element in the period and Element Q the last element.
