The density of an irregularly shaped object was determined as follows. The mass of the object was found to be 28.90 g 0.03 g. A graduated cylinder was partially filled with water. The reading of the level of the water was 6.4 cm3 0.1 cm3. The object was dropped in the cylinder, and the level of the water rose to 9.8 cm3 0.1 cm3. What is the density of the object with appropriate error limits? (See Appendix 1.5.)

As the shopping trip progressed, the cart increased in mass from 0 kg to 10 kg. Which argument below supports Raymond's claim that it was more difficult to push the 10 kg cart as opposed to the empty cart. O As the cart decreased in mass, Raymond had to use more force to push the cart. O As the cart increased in mass, Raymond had to use more force to push the cart. O As Raymond continued to push the cart during the duration of the trip, he became tired which made it more difficult to push the cart. O As Raymond continued to push the cart during the duration of the trip, friction began to build up on the wheels causing the cart to be more difficult to push.
