Answer:
results will be more accurate if there is a larger sample size.
No matter what research is, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably.
With small sample, the chance for false conclusions is higher.

Answer:
Allows farmers to grow plants using very little soil
Explanation:
Fertilizer helps us to return the nutrients to the soil for new or current plants to grow. These nutrients were spent by the plants that were there or the soil was not that rich with nutrients, to begin with. It will not replace soil and growing plants without soil is called hydroponics. Fertilizer is very useful in agriculture currently and most likely will continue to be a good way to grow plants for a while.
Answer:
-300 N
Explanation:
The key words here are "constant speed". By this, we mean that all the forces on the object (the sailing boat here) are balanced - so they must be equal in magnitude.
Here, we know that the boat has a forward force of 300 N. Because the forces are balanced, then the backward force must also have a force with magnitude 300 N.
However, note that because the backward force is in the opposite direction as the forward force, we must put a negative sign on the 300. So our answer is: -300 N.
