An object is completely submerged in oil with specific gravity 0.7.Which statement below is correct?
A)If the specific gravity of the object is greater that 1.0,it will rise.
B)If the specific gravity of the object is less than 0.7,a force downward is required to keep it submerged.
C)If the specific gravity of the object is greater that 0.7,it will float.
D)If the object is hanging from a spring scale,it will weigh more when in the oil than out.
E)If the object has specific gravity 1.0,it will float with 30% of its volume out of the oil.

The specific gravity of an object compared to the fluid it is submerged in determines its buoyancy. If the specific gravity of the object is less than that of the fluid (0.7 in this case), the object will naturally tend to float, and a downward force would be needed to keep it submerged.
