Tera performed multiple experiments to determine the best growing conditions for azaleas. in one experiment, she tested the effect of using different types of soil. in another experiment, she tested the effect of exposing the plants to varying amounts of light. and, in another experiment, she tested the use of different amounts of fertilizer. once she completed her experiments, tera recorded all of her observations before making a conclusion.
this scenario suggests that
a. scientific hypotheses should be made after reaching a conclusion.
b.
scientific explanations are based on evidence, or data.
c.
scientific questions are often solved by performing a single experiment.
d.
scientific evidence includes observations, data, and personal opinions.

Which of the following changes to a pipe would increase the conductance by a factor of 12? 1.quadrupling the length and tripling the radius.2.reducing the length by a factor of and doubling the radius.3.tripling the length and reducing the radius by a factor of .4.reducing the length but a factor of and doubling the radius.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
