Question

Q3) What is the relation between distance and speed?

Q4) On what the time period of a simple pendulum depends?

Q5) Describe how we calculate time period of a simple pendulum.

Q6) Anshika takes 15 minutes from her house to reach her school on bicycle the distance between her house and the school.

Q7) Draw the distance-time graph to show a car moving with a constant speed.

Q8) State one factor which is common in all the clocks​

Answer 1

Answer:

3.The speed of a moving body is the distance travelled by it in unit time. If the distance is in km and time is in hours, then the speed is km/hr. If the distance is in m and the time is in seconds, then the speed is m/sec.

4.length of

Note: The time period of the simple pendulum depends upon the length of the pendulum and also to some extent it depends upon the degree of the amplitude. That is the width of the pendulum's swing. In general, the time period of a pendulum means one complete cycle that is one complete left swing and right swing.

Answer 2

Answer:

Ans 3. Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
