B, Carbon monoxide is the answer :)
<span>This question is based on conservation of energy as the work done would lead to change in kinetice energy of car
change in KE = 1/2 mv(f)^2 - 1/2mv(i)^2 = 1/2m(v(f)^2-v(i)^2)
where v(f) and v(i) are the final and initial speeds
change in KE = 185kJ = 185,000J = 1/2 m((28m/s)^2-(23m/s)^2)
185,000=1/2 m(255m^2/s^2)
solving for m
m=1451kg</span>
Answer:
Product, 
P = 639619.091888
Explanation:
In this case, we need to find the product of two numbers. These are as follows :


On doing calculation, we get the product of two numbers as :


P = 639619.091888
In scientific notation the product of two number is given by :

Hence, this is the required solution.
Explanation:
The current flow of electrons for all of the light bulbs would be interrupted. It is similar or 'breaking' a circuit.
mass/volume = density.
if bigger than water, sinks
less than water floats.
Archimedes' principle, floatation, icebergs etc
