A small metal ball hangs by a thread from a scale. The scale reads 120.0g with the ball just hanging in the air. If a small jar of water lifted up so that the ball is completely immersed in the water without touching the jar itself, the scale reading changes to 70.0g. What buoyant force is the water exerting on the ball?

4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...

In figure A, a ball with a weight of 32.0 N is supported by a
string. The ball hangs over a beaker of fluid. The beaker sits on a
scale, which reads 18.0 N. In figure B, the ball is completely
submerged in the fluid, and the tension in the string is 10.0 N. In
figure C, the ball is exactly half submerged. In figure D, the
string has been cut, and the ball is resting at the bottom of...

LEARN MORE REMARKS Because the density of gold Is 1.93 x 104 kg/m", the crown is elther hollow, made of an alloy, or both. Despite the mathematical complexity, it is certainly conceivable that this was the method that occurred to Archimedes. Conceptually, it's a matter of realizing (or guessing) that equal weights of gold and a silver-gold alloy would have different scale readings when immersed in water because their densities and hence their volumes are different, leading to differing buoyant...

3. Suppose you have a rock with a mass of 305 g. When attached to a spring scale and lowered completely into water the spring scale reads Fe 2.10 N. Note that this reading is significantly lower than the rock's weight Fo Mg (3 N), because of the buoyant force helping to support it. From this information, calculate the following: (a) Fe: the magnitude of the buoyant force exerted on the rock. Use N2L in conjunction with the FBD shown...
