Answer:
Human activities and natural processes have influenced the change in the global temperature by the following processes
1) Green house gas such as carbon dioxide, methane, ozone, nitrous oxide and fluorinated gases produced by the combustion of fossil fuels the use of industrial chemicals, the production of coal, and natural gas
2) Deforestation which reduces the natural process of conversion of carbon dioxide to oxygen, thereby, increasing the greenhouse gases in the atmosphere
3) The accumulation of the greenhouse gases in the atmosphere results in the trapping of heat in the atmosphere, causing the atmospheric temperature to rise
4) Changes in the amount of energy produced by the Sun can result in an increase or decrease in the atmospheric temperature
5) Volcanic activity that occurs at a sufficiently large scale can produce sulfur dioxide that blocks the rays of the Sun from reaching the Earth, resulting in a change of atmospheric temperature.
Explanation:
Answer:
The value in m/s
The value in km/h
Explanation:
Generally the average velocity of the helicopter is mathematically represented as
substituting and 30.0 s for t
We have
=>
Now converting to km/h
=>
Answer:
Energy density will be 14.73
Explanation:
We have given capacitance
Potential difference between the plates = 365 V
Plate separation d = 0.200 mm
We know that there is relation between electric field and potential
, here E is electric field, V is potential and d is separation between the plates
So
Energy density is given by
Answer:
The 1200 kg car
Explanation:
because it has a lot less weight to keep it still
