We will start by defining the units and their respective equivalences between the proposed measurement systems
PART A ) The mileage of the car is 55mpg (Miles per gallon)
Therefore the mileage of the car is 23.4km/L
PART B ) The mileage of the car means that the car travels 23.4km and consumes 1 liter of fuel. Then
For the car to travel 1500km the amount of fuel would be,
But 1 gas tank can only hold 45Liters of fuel, then the number of tank required would be
Thus the number of tanks of gas required to drive 1500km is 1.4

Yes, the answer is in fact C. All of the above.
Variable stars are stars that change in brightness. The change could be due to the physical change in the star or it could also be caused when another star crosses another, or in other words eclipse.
The Geiger–Marsden experiment(s) (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated
Answer:
Explanation:
Given that,
The current in the loop, I = 2 A
The radius of the loop, r = 0.4 m
We need to find the magnetic field at a distance 0.09 m along the axis and above the center of the loop. The formula for the magnetic field at some distance is given as follows :
Put all the values,
So, the required magnetic field is equal to 
.
