Explanation :
From the given information, the graph is plotted.
It is given that, a driver is traveling along a straight road at the speed limit of 60 mph. Initially, he was at point A.
After two minutes, she slows at a constant rate to a stop at a stop light. BC shows this part.
Two minutes later, the light turns green and she accelerates at a constant rate back up to the speed limit. CD shows this part.
Three and a half minutes later, she again slows at a constant rate to a stop. DE shows this part.
Hence, this is the required solution.

Answer:
B) The current of the entire circuit is lowered.
Explanation:
There are two ways in which a resistor can be connected in a circuit;
i) Series: In a series connection, resistors are connected end to end. In this arrangement, the current passing through each resistor is the same while the potential difference across each resistor is different.
ii) Parallel: In a parallel connection, resistors are connected to common junctions. In this arrangement, the potential difference across each resistor is the same while the current across each resistor varies.
In a series circuit, the effective resistance is the algebraic sum of resistance of all the resistors connected in series. Hence, if a large resistor is connected in series, the effective resistance of the circuit is greatly increased.
Since the voltage is given by;
V=IR (Ohm's law)
Where R is the effective resistance
Then;
I = V/R
If R becomes very large due to a large resistance connected in series, then the current of the entire circuit is lowered.
Answer:
no, otherwise they just cause a side effect on our lives
