A charity group wants to give away insect-resistant corn seeds to farmers in poor countries. One of the main insects that harms corn crops in these countries is the corn rootworm. To decide which type of corn to give away, the charity group tests 4 types of corn to see which one the corn rootworms like least.

Data from Rootworm Test

Corn Sample
Name Plant Height
(in feet) Attacked by
Rootworm? Ear Length
(in inches) Pounds per
acre
A 7 yes 8 650
B 4 no 4 2400
C 6 yes 5 1260
D 5 yes 7 450

Some of the farmers receiving the seeds want to grow the corn with the biggest ears because they think this corn will produce the most food per acre. Other farmers think that the tallest plants will produce the most food per acre.

Based on the group's research, which type of corn resists the corn rootworm best and therefore produces the most corn per acre?

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
