Answer: 1.) renewable resources can be replenished as fast as they are used. Nonrenewable resources are unable to be replaced at the same rate at which they are used. 2.) nonrenewable energy sources will eventually run out, leaving people to figure out how to continue running their cars, homes, and busines. They must find alternative sources of energy. Since renewable energy resources that will never run out, it is a great option.

Answer:
Answer: CH₃ and C₂H₆ have same empirical formula.
Explanation:
it just compares in that it its the same
Answer: Between 1 and 2.
Explanation:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
............(1)
where,
a = amount of reactant left after n-half lives = 40
= Initial amount of the reactant = 100
n = number of half lives
Putting in the values we get:
taking log on both sides
Thus half-lives that have elapsed is between 1 and 2

<span>A - moving 2 newton's up 0.6 meter = 1.2 joules
B - moving 4 newton's up 0.6 meter = 2.4 joules
C - moving 6 newton's up 0.3 meter = 1.8 joules
D - moving 9 newton's up 0.3 meter = 2.7 joules
The greatest amount of work is in example D.
