A child's cubic play block has a mass of 120.0 g and sides of 5.00 cm. When placed it is in a bathtub full of water, what fraction of the block will be submerged? (Hint: the density of the water in the bathtub may be assumed to be the same as for fresh water, that is, 1.00 grams/cm3. Note also that if you calculate a number larger than 1 or 100%, this means that the block is sinking and so is 100% submerged.)

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
