The graphs C1 and C2 show the amount of braking (retarding force F) as a function of wheel slip for a vehicle cruising along a road. Slip is defined as (v_vehicle - v_wheel_speed) / v_vehicle expressed as a percentage. Suppose increased braking by the driver increases slip. If graph C2 is applicable (where force decreases after a certain slip point), in which situation should the driver brake harder to achieve maximum braking force? When the current slip is less than the peak of C2 When the current slip is exactly at the peak of C2 When the current slip is greater than the peak of C2 Braking harder always increases force regardless of slip Consider a function "random()", which generates a random number "x" with a uniform probability distribution between 0 and 1. Consider the following program: Y = 0; for (a = 0; a < 1000000; a++) { X = random(); Y = Y + X; } Y = Y / 1000000; print(Y). What is the expected output? 0.0 0.5 1.0 0.25 Consider the following program: Y = 0; for (a = 0; a
