Question

for today's home work --
1. what is oscillation?
2. what is average speed?
3. a bus travels from station A to B has distance of 40 km, in 120 minutes and then from B to C has distance of 60 km in 180 minutes. calculate the value of average speed of bus.​

Answer 1

Answer:

1.regular variation in magnitude or position about a central point, especially of an electric current or voltage.

2.In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position; it is thus a scalar quantity.The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval;the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.

Explanation:

l hope it is correct and it will help you.

Answer 2

1. Movement back and forth in a regular rhythm is called oscillation.

2. In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position; it is thus a scalar quantity.
