This can be solved using Newtons second law M*a=net force
we can sub in that 10000kg*a=200n so then we know its accelerating at a rate of 0.02 m/s^2
using this we can use the equation vf=vi+a*t
we then have 2m/s=0m/s+.02m/s^2(t)
then dividing out the acceleration we find that it would take 100 seconds for the tractor to reach that velocity
Hey :)
Weight is the force acting on the object due to gravity.
Mass is the measure of the quantity of matter that a body or an object contains
Hope this helps :)
Hello! The nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine that have created a hole in the ozone layer are the Chlorofluorocarbons (CFCs)
These are compounds developed and improved by Thomas Midgley in the late 1920s. They were used as refrigerants and aerosol propellants.
These compounds created a hole in the ozone layer by the following reactions:
CCl₃F → CCl₂F· + Cl· (In the presence of light. Radical Reaction)
Cl· + O₃ → ClO + O₂
ClO + O₃ → Cl· + O₂
The last 2 reactions can repeat in a radical mechanism and explain why these compounds are so harmful to the ozone layer.
