Answer:
0.176m from the flagpole, westward.
Explanation:
Let the Eastward be the positive direction. So initially runner A is at position -6km, running with velocity of 9km/h while runner B is at position 5km running at a velocity of -8km/h. We can conduct the following equation for their distances over the same time t


When A an B meets, they are at the same position and at the same time. So





So where they meet is 0.176m from the flagpole, westward.
Answer:
about 0.8 times
Explanation: MARS is a planet named after a Roman God of War, it is the fourth planet from the sun and the Second smallest planet following Mercury.
The orbital Speed of a planet is the speed with which the planet uses to completely go round the Sun.
The orbital Speed of the Earth is 29.78kilmeters per Second.
The orbital Speed of Mar is 0.8*29.78kilometers per second/1
=23.824kilmeters per second.

(Missing question is: which of the following statements are true?)
a) 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) 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>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)]](https://tex.z-dn.net/?f=R%3DR_0%20%5B1%2B%5Calpha%28T-T_0%29%5D)
with

being generally positive, therefore the value of the resistance is proportional to T, and when T decreases, R decreases as well.
d) a battery is a device that produces electricity by transforming chemical energy into electrical energy --> TRUEThat'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.
