Answer any FIVE of the following questions: 1) Draw the posterior graph for rotation with acceleration. 2) State and explain the dimensional law of vector addition. 3) Show that F = ma under usual notations. 4) State and explain Newton's universal law of gravitation. 5) Write Planck's statement or expression for mean free path of gas molecules.
Understand the Problem
The question is asking to answer specific questions related to physics concepts, such as drawing graphs, describing laws of gravitation, and explaining definitions. This requires detailed understanding of various physics principles.
Answer
1. Graph rotation & acceleration. 2. Dimensionally similar vectors can be added. 3. F = ma (Newton's second law). 4. Gravitational force is mass product/distance squared. 5. Mean free path: avg distance between molecular collisions.
- To draw the posterior graph for rotation with acceleration, consider how angular velocity and acceleration change. 2. The dimensional law of vector addition involves quantities with the same physical dimensions being added directly. 3. F = ma relates force (F) to mass (m) multiplied by acceleration (a), derived from Newton’s second law. 4. Newton's universal law of gravitation states every particle attracts every other particle with a force along the line joining them, proportional to the product of their masses and inversely proportional to the square of the distance between them. 5. Planck's statement for mean free path describes the average path length traveled by gas molecules between collisions.
