After completing this Lecture Tutorial, students should be able to:distinguish between scientific hypotheses and nonscientific ideas.Part 1: Comprehension of HypothesesA scientific hypothesis needs to (1) be supported by the majority of current data and (2) betestable. An alien on Earth is wondering why a rubber ball falls back down to the groundafter it is thrown into the air. It comes up with several ideas about the ball.a. Gravity is pulling the ball to the ground.b.A mystical force that cannot be measured is pushing the ball down.c.Earth's magnetic field is pulling on the rubber ball.1. Which statement is NOT a hypothesis because it is not testable? a b c2. Which statement is NOT a hypothesis because it is not supported by current data? a b c3. Which statement IS a scientific hypothesis? a b cPart 2: Application to Dinosaur ExtinctionBelow are possible scenarios explaining the extinction of the dinosaurs.a. Dinosaurs were killed off by a virus.b. A large meteorite impact caused the climate to change, so some plants and animalscould no longer survive.c. Volcanic eruptions caused the climate to change, so some plants and animals could nolonger survive.d. Mammals ate all the dinosaur eggs.4. Determine if each statement above is a valid hypothesis. Explain your answer using therequirements of a scientific hypothesis.a.YesNobecauseb. YesbecausebecausebecauseDA AYesd. YesNoNoNo7IWF

1. Which statement regarding scientific models is true? (a) Models that do not make new predictions are wrong. (b) There can only be one model that explains a set of observations. (c) We design experiments to prove that a given model is correct. (d) Any model that cannot explain the observations is useless and should be discarded. (e) We prove a model is right when we observe the predictions it makes.
Explain how to get the correct answer. It is not enough to just say what the correct answer is; you must explain the thought process behind how someone would get that answer. Explain what mistake you made and, more importantly, something concrete you can do in the future to keep from making this mistake again.
Q1: Tasks to Perform: Automated College Timetable Generator: Most colleges have several different courses and each course has several subjects. Now there are limited faculties, each faculty teaching more than one subjects. So now the timetable needed to schedule the faculty at provided time slots in such a way that their timings do not overlap, and the timetable schedule makes best use of all faculty subject demands. We use a genetic algorithm for this purpose. In our Timetable Generation algorithm, we propose to utilize a timetable object. This object comprises of Classroom objects and the timetable for every them likewise a fitness score for the timetable. Fitness score relates to the quantity of crashes the timetable has regarding alternate calendars for different classes. Classroom object comprises of week objects. Week objects comprise of Days also Days comprises of Timeslots. Timeslot has an address in which a subject, student gathering going to the address and educator showing…
Part I. We will leam in this class that the distance from the Earth to the Sun is approximately 1AU = 150,000,000 kilometers. a. Convert this number to meters (1 kilometer = 10° meters) and express it using scientific notation: 150000000000 meters How else might you express this number? (Millions, billions, etc. ?) b. A car on the highway drives at 55 mph = 25 meters per second. How long would it take to drive to the Sun? (Assuming you have a car that works in outer space.) Use the equation distance = velocity x time, or time = distance / velocity. Time = distance/velocity = , seconds (don't forget to use scientific notation.) How many days?. _days How many years?. years Does the answer surprise you?
Astronomers use a light-year to measure distance. A light-year is the distance light travels in one year. The speed of light is approximately 300,000 km/sec.a. How long is 1 light-year in kilometers?b. The nearest star (other than the sun) is Alpha Centauri. It is 4.34 light-years from Earth. How far is that in kilometers?c. How long will it take a rocket traveling 42,000 km/hr to reach Alpha Centauri?
Calculate the angle a person needs to lean from the vertical when 1. walking a 14 m (radius) circular track at 22 mins per mile, and Enter to 2 significant figures Angle with respect to the vertical = = 0.85 ! No, that's not the correct answer. O 2. running at 4 min per mile. Enter to 2 significant figures Angle with respect to the vertical = 6.8 Use 1 mile = 1609.4 m Sense-making: Do your results for the leaning angle during walking agree with your observations about people walking on circular tracks? O
Choose the correct answer. Briefly explain and show your solution. Thank you.
Identify an interesting application that is relevant to PHY205, describe it, and explain how it works. Pay particular attention to how the content standards you identified as relevant play and use your explanation to demonstrate your understanding of the standard. At the very least, a good description and explanation will raise your rating on C45 and S. Depending on the additional content standards, their relevance to your application, and the depth of your discussion, you will also raise their ratings.

Newton's Law of Gravitation 2. The magnitude of the acceleration of an object under the pull of Earth's gravity is given by Newton's Universal Law of Gravitation МЕ a = G R? where G is the universal gravitational constant, ME is the mass of Earth, and R is the distance of the object from the center of Earth. Let x be the distance above Earth's surface. We can rewrite the formula for the acceleration as a function of x by noting that R = Rp + x, where Rp is the radius of Earth. Therefore, МЕ a(x) = G- (RE + x)2 d. (a) Show that dx 1 1 (1 – x)* - x. (b) Use the above fact, along with the power series of 1 to determine a power 1- x 1 series for (1+x)²* (c) What is the radius of convergence for the series in part (b)? (Hint: You do not need to calculate anything. What is the radius of convergence for the power series of 1 does not change the radius of convergence.) -? This series has the same radius of convergence since taking a derivative
