A cart has a load of 100 kg sand at start and it is pulled by a steady resultant force of 100N starting from rest. A hole in the cart causes steady leakage of 1kg/s. Find velocity v of the cart after 50s of motion.
A Variable Mass type question is a type of scientific question that involves investigating the relationship between two variables, where one variable is continuously changing or varying. It is also known as a parametric question.
Variable Mass type questions allow scientists to understand the cause and effect relationship between variables and how one variable affects another. This helps in making predictions and understanding complex systems.
Some examples of Variable Mass type questions include: "How does temperature affect the rate of photosynthesis?", "What is the relationship between exercise and heart rate?", and "How does the concentration of a reactant affect the rate of reaction?"
Scientists design experiments by manipulating one variable (the independent variable) while keeping all other variables constant. They then observe and measure the changes in the other variable (the dependent variable) to determine the relationship between the two.
One limitation of Variable Mass type questions is that they can only test the relationship between two variables, and do not account for other factors that may also influence the outcome. Additionally, some systems may be too complex to be accurately represented by a single independent variable.
