Answer:
Afforestation is the planting or adding of trees in an area where there was never a forest or plantation. This is a method to create a new forest. Reforestation is the replanting of trees in an area where there was once a forest which was destroyed or damaged.
Explanation:
Answer:
Is a Series Circuit
Explanation:
The circuit shown in the image is a series circuit, is considered as a closed circuit meaning that only has one path for the current to flow with all light bulbs in a row, the voltage applied to the circuit is equal to each voltage drop in the light bulb, if any light bulbs blow out, the current will not flow because the circuit is broken and the remaining light bulb would turn off.
Answer:
D) Acceleration is positive and increasing.
Explanation:
Acceleration is defined as the rate of change of velocity per unit time; in formulas:

where
is the variation of velocity and
is the variation in time.
The graph shows the velocity vs the time of a moving object. We can see that
is the increment on the y-axis, while
is the increment on the x axis: therefore, the ratio
is the slope of the curve. In fact, in a velocity-time graph, the slope of the curve corresponds to the acceleration of the object.
In this particular graph, we see that the slope of the curve continues to increase: therefore, the acceleration is positive (because the slope is positive, since the velocity is increasing) and increasing (because the slope is increasing).
