Answer:
1.
2.
Explanation:
1.Momentum is given as the product of mass by velocity of an object.
Momentum,
m=1,500kh, v=6m/s

2.Momentum,
m=7800kg, v=30m/s

new mass=7800+800=8600
As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

Explanation:
your answer is Kelvin because it is the SI unit of temperature

Answer:
increases
decreases
Explanation:
The distance between particles increases when the temperature increases and decreases when temperature decreases.
- Temperature changes in a system causes the particle of such system to behave in different ways.
- When particles gain heat energy as their temperature increases, they begin to move further apart.
- As their temperature reduces they tend to coalesce.
Answer:
Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
