Asphere completely submerged in water is tethered to the bottom with a string. the tension in the string is one-fourth the weight of the sphere.

what is the density of the sphere?

          ρ = 800 kg/m³

Explanation:

Let the volume of the sphere = V  

and the density of the sphere = ρ

density of water , ρ_w = 1000 Kg/m^3

tension in the string is one-fourth the weight of the sphere.

Tension in the rope ,

for the sphere to in equilibrium

T + Weight = buoyant force

ρ = 800 kg/m³

density of the sphere is equal to 800 kg/m³

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
