Physics: can someone me identify a concept/hypothesis and possible experiment to run? this is supposed to be a mock experiment and not an actual lab completed.
look around and find a certain pattern. describe the pattern / phenomena that you have selected. pretend that you have just performed your observation or observational experiment. you may need to repeat the observation at a later time, if there is a possibility. illustrate it with a photo or a sketch.
devise a hypothesis of what created this pattern or what caused this particular pattern/phenomenon. record it with as much details as possible.
think of how you can check if your hypothesis is valid (design a testing experiment) and record the prediction of this experiment. it is preferable to provide accurate details of your reasoning , assumptions, and the reasoning behind your prediction. why you think the suggested cause-effect link would work? are you making any assumptions? if so, what are they?
identify what quantities you will be keeping track of and how they will connect the predicted cause to the observed effect. what are these quantities? how would you measure these quantities?
perform the experiment. if it is possible at all, video-record your experiment to analyze your actions, including the measurements. you have to trust me for now on this, but the more information you get on your thought, work, and measurements, the easier it would be for you to pinpoint the reason for the prediction to be wrong, if that should happen. there is no need in attaching the movie to your submission, but i would recommend you to keep it among the files on blackboard, so it is within reach if you will need to defend your reasoning.
in one paragraph, explain the results of your experiment. did they match the prediction?
in the summary, reflect on the whole process. if the prediction holds true, what would be the better way to further confirm your idea of the cause-effect connection? if not, revise your hypothesis or suggest a different observational/testing experiment to get a better insight into the pattern/phenomenon

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

Need asap which of these is an example of a hypothesis? (2 points) a. adults were not interviewed b. the investigation was time consuming c. the source of information was biased d. very few teenagers were interviewed scientists in different parts of the world have conducted experiments to find the speed of light in vacuum. if the results of the experiments are identical, they would most likely be (2 points) a.valid b. biased c. unreliable d. non-observable which of these questions can be answered using science? (2 points) a. what is the best career? b. does water exist on venus? c. should the use of automobiles be stopped? d. which is the most interesting subject to study? the models can be best used to (2 points) recreate something which is easily observed in nature prove that all atomic theories have the same meaning demonstrate the transformation of atomic theory into law represent the locations of subatomic particles in different atomic theories 22. (bws.06) scientists earlier believed that the lowest measurable temperature is the freezing point of ice. however, modern scientists believe that temperatures below the freezing point of ice can also exist. what best accounts for these different opinions? (2 points) scientists propose contradictory ideas to include all possibilities scientists come up with different hypotheses without enough evidence scientists propose different ideas to avoid repetition of scientific knowledge scientists having different interests may interpret the same data in different ways based on the graph, what is the most likely mass of an apple chosen randomly from the basket? (2 points) between 0.10 kg and 0.12 kg between 0.12 kg and 0.14 kg between 0.14 kg and 0.16 kg between 0.16 kg and 0.18 kg a scientist studies a model of a widely accepted theory about the position of planets and sun. the model would most likely the scientist to (2 points) prove that the theory would not change in the future demonstrate how the theory can be changed into a law understand facts which cannot be easily observed prove that all other facts about the universe are incorrect one scientist discovered a new theory on the evolution of the universe. what is the next step for the scientist to take? (2 points) transform the results of the theory into universal laws of nature inform the scientific community so they can verify the results call a press conference to make the discovery popular among people encourage scientists worldwide to find an appropriate application for the results the students' observations are listed below. when an iron nail is taken near the north pole (n) of the bar magnet, it is pulled towards the magnet. when an iron nail is taken near the south pole (s) of the bar magnet, it is pulled towards the magnet. the experiment was repeated by several students using different bar magnets. based on the investigations, which of these theories would the students most likely propose? (2 points) magnets attract iron nails the poles of a magnet attract all materials iron nails are attracted towards all materials iron nails have the same properties as magnets
