Answer:
m1*v1 = m2 v2
1200kgm/s=600kg*v1=(7+600)*v2
6000=607*v
v2=9.8m/s

Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
The mesosphere is the coldest layer of the atmosphere.
Hope that helped you.
