1. What three, testable, phenomena were used to confirm the Big Bang Theory?
2. Describe what radioactive decay is, and how a geologist might use it to date a rock sample.
3. Compare and contrast the quantum mechanical model of the atom with the earlier Rutherford model.
4. Assuming that you have unlimited technology, resources, and time, describe an experiment you could create to test Einstein's Theory of Relativity, focusing on time dilation and length contraction.
5. Describe wave-particle duality, and how this relates to Louis De Broglie's postulate.
A boy pushes horizontally with a force of 210 Newton on a 40 kilogram crate to move it across a level ground. The coefficient of kinetic friction is 0.25. Evaluate what is the magnitude of the crate acceleration
If the charge at the center of the sphere is made positive, how is the charge on the inner surface of the sphere affected? (Select all that apply.)
Transverse waves travel at 150 m/s on a wire of length 80 cm that is under a tension of 550 N. What is the mass of the wire
Car A has two times the mass of car B, but only 0.4 as much kinetic energy. Find the ratio between the speeds of the two cars
The dipole moment of a water molecule in liquid water is 6.2×10-30 C•m, and the effective diameter of the water molecule is 2.8×10-10 m. In an earlier homework problem the effective dipole charge separation for water was calculated as 1.9×10-11 m.
