- (a)The radius of an atom is 02 nm The radius of the nucleus is (1)/(10000) the radius of the atom. Calculate the radius of the nucleus. Give your answer in standard form.
- The density of water is 1 gram per cm^3 An object floats in water if its density is less than water's density, and it sinks if its density is greater than water's. Suppose a lime with mass 90 grams is in the shape of a sphere with radius 2.5 centimeters. Will the lime sink or float in water? Explain or show your reasoning.
