Answer:
Plants are a good starting point when looking at the carbon cycle on Earth. Plants have a process called photosynthesis that enables them to take carbon dioxide out of the atmosphere and combine it with water. Using the energy of the Sun, plants make sugars and oxygen molecules.
'A' is correct. B, C, and D are false statements.
Turn lights off, unplug electronics, and use solar energy
Answer:
5.791244495 KNm
Explanation:
The height h is given by,
Potential energy, PE is given by
PE=mgh where m is mass of the woman, g is acceleration due to gravity whose value is taken as
and h is already given hence substituting 77 Kg for m we obtain
PE=21.6567095 KNm
We also know that Kinetic energy is given by
where v is the velocity and substituting v for 20.3 we obtain
KE=15.865465 KNm
Friction work is the difference between PE and KE hence
Friction work=21.6567095 KNm-15865.465 Nm=5.791244495 KNm
Answer:
"Emergency resource guidebook" would provide you with the best initial information about this chemical
Explanation:
This guidebook is for the first responders in case of the beginning of any dangerous goods or the hazardous materials transportation incident. It is used in firefighters, paramedics and for the police officers, in countries like Canada, Mexico and also in the United states when responding to these accident cases becomes delay. The book has different colours in it, for chemicals it will be green colour whereas the blue or the yellow colour shows the toxic inhalation materials. In TIH it has initial isolation distance and protective action distance information against the accident. The white is the host specific.
