Question

wer the following questions:
1. Figure shows a uniform metre rule placed on a fulcrum at its mid-point and having a
weight 40gf at the 10 cm mark and a weight of 20gf at 90cm mark.
(i) Is the metre rule in equilibrium? If not, how will the rule turn?
(ii) How can the rule he brought in equilibrium hy using an additional weight of 40gf
2.Draw a T'vs I graph, where T is the time period and its length of the pendulum. How will
you calculate the acceleration due to gravity from the graph?
3. What do you mean by fundamental quantity and derived quantity Give one example of each?​

Answer 1

Answer:

3.

Explanation:

3.The Fundamental Quantity is independent Physical Quantity that is not possible to express in other Physical Quanitity. It is used as pillars for other quantities aka Derived Quantities. In Physics, Length, Mass, Time, Electric Current, Thermodynamic Temperature, etc are examples of Fundamental
