Achild playing in a swimming pool realizes that it is easy to push a small inflated ball under the surface of the water whereas a large ball requires a lot of force. the child happens to have a styrofoam ball (the shape of the ball will not distort when it is forced under the surface), which he forces under the surface of the water. if the child needs to supply 5.00×102 n to totally submerge the ball, calculate the diameter d of the ball. the density of water is ? w=1.000×103 kg/m3, the density of styrofoam is ? foam=95.0 kg/m3, and the acceleration due to gravity is g=9.81 m/s2.

0.47556 m

Explanation:

= Child supplying force = 500 N

W = Weight of foam

F = Force on air

g = Acceleration due to gravity = 9.81 m/s²

By balancing the forces we get

The diameter of the ball is

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
