Part C For each source of energy, describe its strengths and weaknesses with respect to the ideal source you described in part A. Do Internet research, as needed, to describe each energy source.

Question 1
Describe at least two advantages and two disadvantages of using natural gas as a source of energy.

See explanation

Explanation:

Natural gas is mined along with crude oil in many oil wells. It has the advantage of being a cheap fossil fuels which is easily obtainable.

Generally, natural gas is the cleanest of all the fossil fuels. This means that it is the fossil fuel that least contributes to environmental pollution.

On the other hand; natural gas produces some amount of sulphur as it is burnt and mercury as particulate matter. These substances are quite dangerous to health.

Secondly, the combustion of natural gas leads to the production of the oxides of nitrogen which play a key role in the occurrence of photochemical smog.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
