Eclipses, both solar and lunar, follow a cycle of just over 18 years [yr], specifically 6,585.32 days [d]. This is called the Saros Cycle. One Saros Cycle after any given eclipse, an almost identical eclipse will occur due to fact that the Earth, the Moon. and the Sun are in essentially the same positions relative to each other. The Sun, and the entire solar system, is moving relative to the Cosmic Microwave Background Radiation (the largest detectable frame of reference) at roughly 370 kilometers per second [km/s). How far does our solar system travel through the universe in one Saros Cycle? Express your answer in the following units:
a. meters [m], with an appropriate Sl prefix such that there are only one, two, or three dtgtts shown to the left of the decimal.
b. light-years: one light year= 9.46 × 1015 meters [m].

- Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires. Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C. When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew? Q2. Your car tire pressure sensor looks to see when your tire pressure…arrow_forwardFor the Following question Graph all 4 : [I just need all 4 graphs and please explain and make clean solution] Position vs time Velocity vs time Acceleration vs time Force vs time [For your convenience, I have solved the numerical solutions for the problem] (Please Look at the picture since it is much cleaner) Question : A 550 kilogram mass initially at rest acted upon by a force of F(t) = 50et Newtons.

- On an alien planet, the law that expresses the flow of blood through a blood vessel, F, as a function of the radius r of the vessel is f=kr5/2where k is a constant. Certain geological features of this planet produce a gas that changes the radius of blood vessels by 5% at the time of inhalation. What would the corresponding increase in blood flow through the vessel at this time be?

- The Ideal gas law shows the relationship between some common properties of ideal gases and is written as PV = nRT. P = pressure, V = volume, n = number of moles of ideal Gas, R = General gas constant = 8.314 kJ/(kmol.K) and T = absolute temperature. 5 mol ideal gas at 22°C is placed in a cube with edge lengths of 0.750 meters.

Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)arrow_forward
