Ipatiy [6.2K]
(Missing question is: which of the following statements are true?)

a) <span>A battery does work on electric charges to bring them to a position of higher electric potential energy so that they can flow through a circuit to a lower potential energy --> TRUE
That's true: the battery does the work to move the charges to one end of its terminal thus creating a potential difference between the two terminals. Then, when it is connected to the circuit, charges start to flow to the terminal at lower potential (through the circuit)

b) </span><span>the potential difference between the terminals of a battery, when no current flows to an external circuit, is referred to as the terminal voltage --> FALSE
This is false: when no current flows, it is called e.m.f. (electromotive force)

c) </span><span>the internal resistance of a battery decreases with decreasing temperature 
--> TRUE
In fact, the dependence of a resistance with the temperature is:
</span>R=R_0[1+\alpha (T-T_0)]
with \alpha being generally positive, therefore the value of the resistance is proportional to T, and when T decreases, R decreases as well.

<span>d) a battery is a device that produces electricity by transforming chemical energy into electrical energy --> TRUE
</span><span>That's true: a battery uses chemical reactions to create a potential difference between the two terminals that can be exploited to make charges flowing through a circuit.

Suppose we have a space ship orbiting the earth. What must happen in order for the spaceship to leave orbit and fall back toward
sdas [7]

Answer:

#2) The spaceship's forward motion must be slowed down so the earth's gravitational pull on it will be stronger than the ship's forward motion.

Distribution intensity is commonly divided into three levels:
gregori [183]
It is indeed divided into Intensive, exclusive, and selective disribution. let me explain them. When we talk about Intesive distribution we say that we have a strategy that is designed to place products in as many outlets as possible. The exclusive distribution is when we recognize policy by granting exclusive geographic territories to one or very few retail customers so no other retailers in the territory can sell a particular brand. And when we talk about selective distribution we know that it <span>lies in between the intensive and exclusive distribution strategies because it uses a few selected customers in a territory</span>
