Chapter 3, Problem 1Q
One car travels due east at 40 km/h. and a second car travels north al 40 km/h. Arc their velocities equal? Explain.
Expert Solution & Answer
To determine
Whether the velocities of the cars are equal or not.
Answer to Problem 1Q
The velocities of the cars are not equal since their direction of motion are different.
Explanation of Solution
Velocity is a vector quantity. It have both magnitude and direction. If two objects are said to be moving with same velocity, they must have same speed (magnitude of velocity) and they must be moving in the same direction.
In the given situation, one car is moving at

The planetary model of the atom pictures electronsorbiting the atomic nucleus much as planets orbit the Sun. Inthis model you can view hydrogen, the simplest atom, ashaving a single electron in a circular orbit 1.06×10−10 m indiameter. (a) If the average speed of the electron in this orbitis known to be 2.20×106 m/s , calculate the number ofrevolutions per second it makes about the nucleus. (b) Whatis the electron’s average velocity?
