Question

Archimedes Principle - Upward Tension Additional Force As shown in the above figure, a solid object has a density of 1200 kg/m3 and a volume of 7.80x10^-5 m3. It is lowered on a string into water and completely submerged without touching the container. The density of water is 1000 kg/m3. Keep 3 decimal places in all answers. (Don't use scientific notations.) Without the string, would the solid object sink in water or float in water? No submission. (a) What is the magnitude of the weight (in Newtons) of the object? Enter a number N Submit (5 attempts remaining)
please answer all these questions
