Answer:
Option D. 3 ppm isopropanol.
Explanation:
From the question given above, the following data were obtained:
Mass of isopropanol = 6 mg
Mass of water = 2 Kg
Isopropanol concentration =?
Concentration = mass isopropanol / mass of water
Isopropanol concentration = 6 mg / 2 kg
Isopropanol concentration = 3 mg/Kg
Next, we shall convert 3 mg/Kg to ppm. This can be obtained as follow:
Recall:
1 mg/Kg = 1 ppm
Therefore,
3 mg/Kg = 3 ppm
Thus, the isopropanol concentration is 3 ppm.

Explanation:
Kinetic energy is the energy of a substance or object due to the motion of its particles.
Mathematically, K.E =
Therefore, more is the velocity of an object more will be its kinetic energy.
Since velocity of a large tractor-trailer is 75 km/hr, therefore, its kinetic energy will be more than the kinetic energy of given small sports car.
