D, I hope this is correct!
Answer:
13 m in the + x direction.
Explanation:
Givens
m1 = m
m2 = 3m
v1= ? = x
v2 = - 3 m/s
v3 = v4 = - 1 m/s
Equation
Let x be the speed of the lighter object before collision.
Momentum before collision = momentum after collision
Solution
mx - 3m * 3m/s = (m1 + m2)*(-1)
m(x - 3*3m/s) = (m + 3m)(-1)
m(x - 9) = - 4m Cancel the ms
x - 9 = 4 Add 9 to both sides
x = 9 + 4
x = 13 m/s
I believe the answer is <span>c. Factor 1 is a natural factor and Factor 2 is a human induced factor.
The amount of heat received by the sun has increased because of the amount of CO2 which human expelled to the atmosphere.
Because of this CO2, the heat from the sun couldn't be reflected outside the atmosphere and trapped within the earth.</span>
Answer:
The movement of polar bears help figure out the impact of global warming in the arctic. Since polar bears travel over the frozen ocean they are able to determine the rate it melts as the bears retreat inland. The worse global warming become the quicker it becomes hotter in the arctic which is bad by the way.

Explanation:
To see the full height of the child the height of the mirror should be half of the height of the child
As it id given that the height of the child is 1 meter so the height of the mirror is 
As it is a rule that to see the full any object the height of the mirror should be half of the height of the object
