True, acid rain is a secondary pollutant
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons and nitrogen oxides combine in the presence of sunlight, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
Thermal energy is the total energy of all the molecules in an object. The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object's molecules (states of matter).
Hope this helps
Answer:
Height will be equal to 0.4489 m
Explanation:
We have given mass of the toy m = 0.50 kg
Initial kinetic energy K = 2.2 J
We have to fond the height of the hill over which car roast
When car will roast the hill its kinetic energy will be converted into potential energy and at maximum height all kinetic energy will be converted into potential energy
So at maximum height 
Acceleration due to gravity 
So 0.50×9.8×h = 2.2
h = 0.4489 m
