Researchers at a university want to know if higher levels of nitrogen in fertilizer will increase the production of tomatoes per plant. twenty plants are given normal levels of nitrogen and twenty other plants are given ten percent higher levels throughout the growing season. the plants receive the same levels of sunlight, water and are planted in the same soil on one farm. at the end of the experiment the average number of tomatoes produced is the same for each group. the scientists repeat the experiment on two additional farms further south that season. the researchers conclude that increasing nitrogen levels by 10% in tomatoes is not beneficial. would this be a well designed reliable experiment? support your decision with at least three reasons.

Yes

Explanation:

It would be because:

1. They tested Twenty Plants therefor they tested the subject multiple times.

2. They were all in an controlled environment in an farm.

3. It was repeated by 2 additional farms.

hey lol my dogs eatting my shoe.

Explanation:

-Yes, this would be a well-designed and reliable experiment because they tested 20 plants, therefore they tested multiple plants resulting in similar results. The text also states that 2 additional farms, farther out south and the same season, tested the experiment. For all the experiments, they were tested inside farms, controlled environment farms.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
