If i put a ball in a bucket it floats. I took the bucket to the moon.  Will it float or not? Why?

answered-by-expert Expert Answer
floating of object in a liquid depends on the difference in  weight of object and weight of displaced liquid.
if weight of the object is less than weight of displaced liquid then the object will float.
Weight of displaced liquid = V×ρw ×g . where V is volume, ρw is density of water and g is acceleration due to gravity.
Since volume and density will not change whether on earth or moon, weight of the object and
weight of the displaced liquid are affected in similar manner due to acceleration due to gravity,
 
Hence. if the ball floats in water on earth surface, it will also float in water on moon

(3 X 3 = 9) CASE STUDY QUESTION 26. Ultrasounds can be used to detect cracks and flaws in metal blocks. Metallic components that are generally used in construction of big structures like buildings, machines and also scientific equipment. The cracks or holes inside metal blocks, which are invisible from outside, reduce the strength of the structure. Ultrasonic waves are allowed to pass through the metal block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of flaw or defect. Clearly indicated in the figure Defect or flaw Ultrasound Detectors Metal Block (a) The transmitter sends an ultrasound wave of speed 5960m/s through a long steel bridge and a block reflects it back after 0.02s. how far the block in the metal bridge is from the transmitter. (b) With the above property of ultrasound waves, Can ultrasonic waves be used in the medical field? If so, how and give one use in the medical field to justify your answer? (c) Give two practical applications of reflection of sound waves?
