Question

Question asked by Filo student

30. Does the buoyant force depend on the density of the solid that has been immersed in a liquid? 10. 1. A ball is dropped from a height of $20 m$ . a. Calculate the average acceleration of the ball. b. Calculate the average velocity for its downward motion until it hits the ground. c. Find the time taken for the ball to hit the ground. 2. Answer the following questions. a. Write four differences between mass and weight. b. What do you mean by inertial mass? c. How can you measure inertial mass? 3. A ball is dropped from a tower of height $2, 000 m$ . Another ball is thrown up with a speed of $20 m / s$ . Where will both the balls meet? 4. Explain the concept of zero gravity in detail. Is it the same as weightlessness? How does an astronaut control his movement during weightlessness? 5. For a planet, ' $g$ ' on its surface is $1/4$ th of that on the Earth. If mass of the planet $= 4$ times
