Abeaker of water rests on a scale. a metal ball is then lowered into the beaker using a string tied to the ball. the ball doesn't touch the sides or bottom of the beaker, and no water spills from the beaker. does the scale reading decrease, increase, or stay the same. explain.

The reading on the scale increases due to buoyancy

Explanation:

A beaker of water rests on a scale. A metal ball is then lowered into the beaker using a string tied to the ball. The ball doesn't touch the sides or bottom of the beaker, and no water spills from the beaker.Does the scale reading decrease, increase, or stay the same. Explain

The reading on the scale increases due to buoyancy

buoyancy is the upward vertical force exerted by a fluid upon a  body

Archimedes' principle states that “When a body is immersed completely or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by the body.” Applications: A hydrometer uses Archimedes' principle to determine the density of any liquid

the buoyant forces bring about an increase in the mass measurement on the scale

the answer is b ) square root of 5

6 cos 34, 6 sin 34 trig
