What will happen in the market for Electric Vehicles (EVs) if simultaneously the price of electricity (a complement for EVs) increases significantly and a global lithium shortage increases the manufacturing cost of producing EV batteries?

Suppose there are two goods to be produced and two countries that can produce them: the United States and South Africa. The table below shows the maximum amounts that can be produced in a day. Note that the numbers below reflect the total that can be produced when only producing that good in a day (e.g., South Africa can either produce 500 jewelry or 100 agricultural products).     Jewelry Agricultural Products    South Africa 600                                 OR 100   United States 800                                 OR 200   Match the statements below with the correct answer choice. 

A circular metal ring is located directly above a long straight wire, as shown in the figure. The straight wire has a current flowing to the right, and the current is increasing in time at a constant rate. Which statement is true?

The phase angle is the amount by which the voltage and current are out of phase with each other in a circuit. An AC series RC circuit is made up of a resistor that has a resistance value of 20 Ω and a capacitor that has a capacitive reactance, XC, value of 30 Ω. Calculate the phase angle of the circuit to the nearest degree. 

A 4.0-cm tall object is placed 60 cm away from a converging lens of focal length 30 cm. What are the nature and location of the image? The image is
