QUESTION 1 1 points How was the overthrow of the European empires (process known also as decolonization) in 20th-century Asia, Africa, the Caribbean, and Pacific Oceania different from the end of the European empires in the Americas in the 16th/19th centuries? O A. It wasn't. In both cases, the same kind of independent countries emerged as a result of the overthrow of the European empires 8. The newly independent states in the Americas were democratic (like the US) while the newly independent states in Asia, Africa, the Caribbean and Pacific Oceania were mostly communist as a result of the Cold War. c. While in the Americas revolutions led to the overthrow of the empires, in Asia, Africa, the Caribbean, and Pacific Oceania all newly independent states ended colonialism peacefully. Europeans simply left because they could no longer defend their Imperial control D. In the Americas many of the colonized people were themselves of European origin so they shared much of their culture with their colonial rulers Many aspects of that culture continued after the former colonies became independent states. In contrast freedom struggles in Asia Africa the Caribbean, and Pacific Oceania affirmed the vitality of local cultures, which had been submerged and denigrated during the colonial era

Answer the following questions about the properties of electric field lines. a. At what two types of locations can electric field lines start? b. Where can they end? c. When looking at an electric field line representation of an electric field, how can you tell from the electric field lines where the electric field is strong and where it is weak? C x E x D x-1 -1 B xA x d. If the number of electric field lines entering or leaving a charge doubles, what does that tell you about the magnitude of the charge? i. It became half as much. ii. It doubled. iii. ....you can’t tell anything about the magnitude of a charge by the number of lines entering/leaving.

Equilibrium - Tension: 1. Two objects of masses 4 kg and 6 kg are connected by a rope over a pulley. If the system is in equilibrium, find the tension in the rope. 2. A sign weighing 150 N is hung by two cables at angles of 20 degrees and 70 degrees with the horizontal. Calculate the tension in each cable. Stress: 1. A rod with a cross-sectional area of 0.01 m$^2$ is subjected to a force of 3000 N. Determine the stress in the rod. 2. A material has a force of 500 N applied over an area of 0.05 m$^2$. Calculate the stress on the material. Strain: 1. A wire stretches by 0.01 meters when a force is applied. If the original length is 1 meter, calculate the strain. 2. The strain in a material is measured to be 0.003. If the original length is 3 meters, determine the change in length.
