A 0.0200-Ω ammeter is placed in series with a 10.00-Ω resistor in a circuit.(a) Draw a circuit diagram of the connection.(b) Cal
culate the resistance of the combination.(c) If the voltage is kept the same across the combination as it was through the 10.00-Ω resistor alone, what is the percent decrease in current?(d) If the current is kept the same through the combination as it was through the 10.00-Ω resistor alone, what is the percent increase in voltage?(e) Are the changes found in parts (c) and (d) significant? Discuss.

Answer:
12.6332454263 m/s
Explanation:
m = Mass of car
v = Velocity of the car
= Coefficient of static friction = 0.638
g = Acceleration due to gravity = 9.81 m/s²
r = Radius of turn = 25.5 m
When the car is on the verge of sliding we have the force equation
The speed of the car that will put it on the verge of sliding is 12.6332454263 m/s
