Frequently Asked Questions (FAQs) on Motion Q1: What is motion? Ans: Motion is the change in an object’s position with time. It can be observed directly, such as a car moving, or inferred indirectly, like the movement of dust particles indicating air motion. Q2: How can we describe the position of an object? Ans: The…
Aim To verify the laws of combination of resistances (series and parallel) using a metre bridge. Apparatus and Material Required Principle When two resistances \(R_1\) and \(R_2\) are connected in series, the resistance of the combination \(R_S\) is given by \[R_S = R_1 + R_2\] When these two resistances are connected in parallel, the resistance of…
\(\vec a = x \hat i + y \hat j + z \hat k\) \(\vec a = x \hat i + y \hat j \) \(x \hat i + y \hat j \) \(x \hat i + y \hat j + z \hat k\) dot product \(\vec a \cdot \vec b\) cross product \(\vec a…
Hydrogen Line spectra – Bohr’s Model Approach According to the third postulate of Bohr’s Model, whenever an electron jumps from higher energy level (orbit) of a Hydrogen atom to one of its lower energy level, an electromagnetic wave (em wave) emits. The energy of em wave is equal to the energy difference between the two…
