Answer:
17.64 km/h
Explanation:
mass of car, m = 1000 kg
Kinetic energy of car, K = 1.2 x 10^4 J
Let the speed of car is v.
Use the formula for kinetic energy.
By substituting the values
v = 4.9 m/s
Now convert metre per second into km / h
We know that
1 km = 1000 m
1 h = 3600 second
So, 
v = 17.64 km/h
Thus, the reading of speedometer is 17.64 km/h.

Answer:
Milk.
Explanation:
Density is used to describe how much space an object or substance takes up in relation to the amount of matter in that object or substance (its mass).
Another way to put it is that, density of a substance is the amount of mass of that substance per unit volume. If an object is heavy and compact, it has a high density.
Density = mass/volume
So,
Milk = 1.035 g of milk per 1 ml
Olive oil = 0.85 g of olive oil in 1 ml.
Therefore, milk has a higher mass.
Dissolving can separate the three. Because pepper doesn't mix with water and neither do pebbles.
