Question 1 (1 point) Solids, liquids and gaseous phases of matter may interact by van der Waals forces, which are weak electrostatic intermolecular bonds that form between neutral molecules. True False Question 2 (1 point) Hydrogen bonding is the only type of van der Waals force exhibited in the water molecule. True False Question 3 (1 point) Solids may be classified as crystalline or amorphous. True False Question 4 (1 point) Solid to liquid phase is known as sublimation. aaPM...

Can someone explain me this question please. Thanks in

Countries with poor property rights enforcement generally have lower income per person than those with better property rights protection. What can the government of a relatively poor country do to promote economic prosperity? Check all that apply. Establish and enforce strong property rights. Encourage transmission of knowledge by removing patents and copyrights. Promote free trade by reducing or removing tariffs on imports from foreign countries. Encourage its officials to facilitate...

someone please help me with this??
Question 2) Some countries have chosen to join currency unions, such as European Union. This would imply sacrificing their own currencies in favor of using a common currency. a. What is the implication of this exchange rate policy for domestic monetary policy? Explain in detail. b. If a country ina currency union can set its interest rate independently, what can you say about the capital markets in this country? Explain in detail.
