Help pls: physics A car with mass 1750 kg travels on a flat circular track with radius
80.0 m at constant
speed 35.0 m/s. What horizontal acceleration does the driver experience during the turn?
(a)
4.5 m/s2
(b) 6.8 m/s2
(c) 10.2 m/s?
(d) 15.3 m/s?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.

What will a positive and a negative charge do if they are separated from each other?
