When a graph between two physical quantities is a straight line, the two quantities are
If two quantities have same dimensions, they represent same physical quantities.
What is the difference between a physical quantity and dimensions?
Like.. length, mass and time are both physical quantity and dimensions? Then, what's the difference between them?
Name the two physical quantities which can be ibtaobta from velocity-time graph
Name the two physical quantities apart from velocity and time which can be obtained from velocity-time graph.
If the graph of the graph between two quantities is a straight line, the quantities:
1) must be both constant
2) must be proportional to each other
3) may be proportional to each other
4) must be equal
( also there is no graph attached along with it and it's all the information that I give so please tell me the answer and please don't reject it this time. thank you)
