To calculate the average speed of the car, we need
B. The total distance driven on the racetrack
Explanation:
The average speed of an object in motion is given by
where
d is the distance covered by the object
t is the time interval considered to calculate the speed
The SI units of the speed are metres per second (m/s).
In this problem, we know the time interval:
t = 30 s
Therefore, in order to find the average speed, by looking at the equation we see that we also need the total distance driven by the car, so the correct answer is
B. The total distance driven on the racetrack

This process of physically separating a single phase mixture into several components would be termed simple distillation, I believe.
As it is mentioned that one is separating them based on their different boiling points.
Answer:
A. Generator
Explanation:
An alternator which is also called a generator basically converts mechanical energy into electric energy.
An alternator is used in a vehicle to charge the battery. It supplies electric power to the automobile.It is attached to the engine and is driven by a belt system . When the alternator does not charge the battery, it can be understood that it is not working as it no longer recharges the battery, though the engine of the automobile runs.
Answer:
im pretty sure it is 3.0 K
Explanation:
<u>Solution and Explanation:</u>
The following calculation is made in order to find out the area and the final velocity vector.
Using the given information and the data in the question,
m1u1 + m2u2 = (m1 + m2) multiply with v
40000 multiply with ( -20i ) + 60000 multiply with ( 10j ) = 100000 multiply with v
Therefore, v = -8i + 6j
That is |v| = 10 knots towards the 36.86 degree north of the west
