A fishing bobber of unknown mass is a sphere with diameter of 3.00 cm. When the bobber is attached to only a fishing line of negligible mass and a hook with a mass of 3.00 milligrams, the bobber floats with 98% of its volume above the surface of the lake. When a worm weighing 0.0245 N is attached to the hook, the bobber floats with 95% of its volume above the surface of the lake. Ignore the buoyancy forces on the hook and worm (they are small in comparison to the buoyancy force on the bobber). Lake water has a density of about 1000 kg/m'.

A fishing bobber of unknown mass is a sphere with diameter of 3.00
cm. When the bobber is attached to only a fishing line of negligible
mass and a hook with a mass of 3.00 milligrams, the bobber floats with
98% of its volume above the surface of the lake. When a worm
weighing 0.0245 N is attached to the hook, the bobber floats with 95%
of its volume above the surface of the lake. Ignore the buoyancy forces
on the hook and worm (they are small in comparison to the buoyancy
force on the bobber). Lake water has a density of about 1000 kg/m.
a) Find the mass of the bobber.
b) Find the density of the bobber.
c) Find the weight (not mass) of the worm.
d) A fish swims up and tries to eat the worm- what is the minimum force that the fish will need to pull
with in order to completely submerge the bobber?
