- I need help answering these two conceptual questions. Thank YOUQUESTION 10 Which of the following physical quantities is not fundamental? a. 3.0 years b. 1,200 kg O c. 12 hours d. 45 cm/s O e. 4.0 miles1 / 1|. 100% +| E - Paper Homework (counts as Reading Assignment) Рар Solve the following two problems, showing all work and expressing your answer in the proper units. You do not need to use the rules for significant digits, but the precision of your answer should be comparable to the precision of the quantities given. 1. Note: Koalas tend to fall out of trees. Their skulls have properties that tend to protect them from concussions and other damage, so we can be happy about that. A koala falls 2.6 m from a tree. Calculate its velocity just before hitting the ground (unharmed). Use the sign of the velocity to indicate direction (up or down).
