Q.8 When a potential difference of 221 V is applied to two plates of a parallel-plate capacitor, the inner surface of the positive plate carries a surface charge density of 40 nC/cm2 . The permittivity of a vacuum is 8.85419 × 10^?12 C 2 /N · m2 . What is the spacing between the plates? Answer in units of µm
Jack and Jill ran up the hill at 3.3 m/s . The horizontal component of Jill's velocity vector was 2.0 m/s. What was the angle of the hill? Illustrate what was the vertical component of Jill's velocity?

A person with perfect pitch sits on a bus bench listening to the 445 Hz horn of an approaching car. If the person detects the frequency of 488 Hz, how fast is the car moving.
When a portable fan is first turned on it draws 4.62 A. After it has come up to speed it draws 0.55 A. calculate the back emf while the motor is running
A small ball of 53 grams is suspended from a string of length 86 centimeters and whirled in a circle lying in the horizontal plane. If the string makes and angle of 31 degrees with the vertical, find out the centripetal force experienced by the ball...
A roller coaster is towed up an incline at a steady speed of 0.51m/s by a chain parallel to the surface of the incline. The slope is 2.85 % that means that the elevation increases by 2.85 m for every 100m of horizontal distance.
