You want to determine the effect of a certain fertilizer on growth of orchids grown in a greenhouse. Materials that are available to you include: greenhouse, 100 orchid plants, water, fertilizer, and soil. You want to know if the orchids will grow best with a weak concentration of fertilizer, a medium concentration of fertilizer, or a high concentration of fertilizer. How will you design an experiment to test different concentrations of this fertilizer?

a. State your hypothesis:

b. How will you set up a controlled experiment?

Yes

IF a high concentration of fertilizer is used, THEN orchid plants will grow best

Explanation:

The hypothesis in an experiment is the testable explanation given in support of an observer problem. It is a predictive statement that aims at proferring a possible solution to a problem or answer a question asked. The hypothesis must be able to be tested via experimentation as this is one important feature all hypotheses must possess. A hypothesis is usually written in an "IF, THEN" format.

In this question, an investigation is being carried out to know the effect of a certain amount of fertilizer on the growth of orchids in a greenhouse. A possible explanation/hypothesis will be:

IF a high concentration of fertilizer is used, THEN orchid plants will grow best.

This can be accepted or rejected depending on the outcome of the experiment.

Answer:

Step-by-step explanation:

The input force is 50 N. But it will not create not any change. No mechanical advantage is observed.
