Information has just come in via satellite that a tsunami has been located off Hilo, Hawaii. The tsunami is at an ocean depth of 4500m. National authorities are trying to establish how
much preparation time the following cities will have:
San Diego, California
Newport, Oregon
Kodiak, Alaska
.
The national authorities have contacted you to compute the amount of time before the
tsunami reaches each of the above locations. As a scientist and mathematician you know
that the speed of tsunamis can be modeled by:
S(d) = 9.80
where d is the depth of the tsunami in meters
S(d) gives the speed of the tsunami in meters per second
Use this equation for speed, the internet to find the distance from Hilo to the above three
cities, and your knowledge of rates to calculate the time it will take for the tsunami to reach
each location. This calculation is an approximation. Round to 2 decimal places and be sure
to use appropriate units. 1) km/hr : of the Hilo tsunami:. 2) km: From Hilo to San Diego . From Hilo to Newport . From Hilo to Kodiak . 3) hr and min: From Hilo to San Diego . From Hilo to Newport . From Hilo to Kodiak. 4) Are there any concerns you have with validating the reasonableness of your solution? 5)what are some factors that may play a role in the speed at which a tsunami travels? 6)Seismology have just registered a large underwater earthquake near Sand point Alaska that is big enough to produce a tsunami. The ocean depth is unknown but it took 5hrs to reach Monterey California. Estimate the depth of the ocean where the tsunami originated.

Study published in the journal of personality and individual differences found that adults with adhd displayed more creative achievement than those who didn't have the disorder. "for the same reason that adhd might create problems, like distraction, it can also allow an openness to new ideas," says holly white, assistant professor of cognitive psychology. "not being completely focused on a task lets the mind make associations that might not have happened otherwise." white and priti shah at the university of michigan gave 60 college students – half of them with adhd – a series of tests measuring creativity across 10 domains. the adhd group scored higher across the board. the adhd group showed more of a preference for brainstorming and generating ideas than the non-adhd group, which preferred refining and clarifying ideas. the adhd status of the participants was established by asking whether the individual had ever been clinically diagnosed with adhd/add. the tests of creativity were pencil-and-paper tasks administered in a laboratory setting. each of the ten scales was comprised of multiple questions, the scores on which were summed (e. g., writing creativity: "how many words can you make from the letters in the word 'psychology' invention creativity: "write down as many uses for a paper clip that you can think of.") this procedure does allow for a participant to be scored as showing no creativity under these conditions. a) state the research question in plain language (i wonder if is related to (1 point) b) state the null hypothesis (1 point) c) state the research hypothesis (1 point) d) is the research hypothesis directional or non-directional (1 point) e) name the predictor / independent variable f) give the operational definition of the predictor / independent variable g) evaluate the construct validity of the predictor / independent variable. (face, procedure, method-match) h) name the outcome / dependent variable i) give the operational definition of the outcome / dependent variable. j) evaluate the construct validity of the outcome / dependent variable.
