I am really struggling with this question because I can't find anything on aphelion and perihelion, it's not a topic we went over because it is an extra assignment. 4. How far away from the sun was Mercury at aphelion? On what day did aphelion occur? 5. How far away from the sun was Mercury at perihelion? On what day did it occur? 6. How many days elapsed between aphelion and perihelion? What percent of the time to complete one orbit was this? 7. What was the average radius of Mercury in its orbit that you calculated? How does it compare to the accepted value of 0.387 AU? Calculate the percent error using the following equation. Show your work. If someone could explain it to me I would really appreciate it!
As shown in the diagram below, a proton (p), mass 1 u, travelling in the +x direction with speed vpi, collides elastically, not head-on, with a stationary deuteron (d) with mass 2 u. (Here u means the atomic mass unit. 1 u = 1.66 x 10-27 kg, but you may not need this number if you can get it to cancel out of your equations). After the collision, the proton is observed to be moving in the +y direction.
How is the force of gravity mathematically related to the factors that answer question 1? 1.what three variable factors determine the force of gravity between any two objects
The inhabitants of a small island begin exporting beautiful cloth made from a rare plant that grows only on their island. Seeing how popular the small quantity that they export has been, they steadily raise their prices. A clothing maker from New York, thinking that he can save money by "cutting out the middleman," decides to travel to the small island and buy the cloth himself. Ignorant of the local custom of offering strangers outrageous prices and then negotiating down, the clothing maker accepts (much to everyone's surpise) the initial price of 400 tepizes/m2. The price of this cloth in New York is 120 dollars/yard2.
A sample of metallic frewium weighs 185N on a spring scale in air. When immersed in pure water, the frewium pulls on the scale with a force of 155N. What is the buoyant force provided by the water? What is the density of metallic frewium?
