solution for number 21 please
19. An aluminum ball of mass 54.0g and density of 2.70g/mL is placed in a beaker filled with water. What is the buoyant force of water on the ball? Answee 0.196 20. The area of contact between an injection needle and the skin is a very tiny circle with a diameter of 2.54x10-3cm. If the needle exerts a force of 6.9x10 2N, what is the pressure in Pa?
