Concept explainers
Explain all answers clearly, with complete sentences and proper essay structure, if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
What are the Odds? The fact that all the planets orbit the Sun in the same direction is cited as support for the nebular hypothesis. Imagine that there’s a different hypothesis under which planets can be created orbiting the Sun in either direction. Under this hypothesis, what is the problibility that eight planets would end up travelling in the same direction? (Hint: It’s the same as the probability of flipping a coin eight times and getting all heads.)

- Read the following items carefully. State your assumptions if any. Show your COMPLETE solution and BOX your final answers. Keep your answers and solutions in 4 decimal places. > Initially, 100 milligrams of a new radioactive substance Tobium, named after its discoverer Sir Tobs, was discovered and collected from one of the moons of Jupiter. After 6 hours from collection, the mass decreased by 4%, If the rate of decay IS proportional to the amount of the substance present at time t, find the amount of Tobium remaining after 48 hours.arrow_forwardFor this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha, Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting nucleus will now change (as compared to your starting nucleus) by O A. zero O B. minus 1 OC. minus 2 O D. minus 3arrow_forwardUsing Kepler's 3rd law solve the following problem. Show your work and highlight your answer. In a distant star system there are many inhabitable planets. One of these planets is named Qomar. Qomar is 3.2 AU's from its star and takes 6.5 Earth years to go around its star once. There is another planet in the same star system called Ferenginar. Ferenginar is 0.9 AUs from the star. What is the length of a Ferengi year (on Ferenginar) in terms of Earth years?arrow_forward
- Write a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below. For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer. hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.arrow_forwardSee the screenshot uploaded.

Take note that the units on the scale are in nanometers (nm), 1 nm = 10-9 m. Record the droplet radius and the 'AV between plates' values in Data Table 1 below. You are viewing the drop that is in Equilibrium 6. Repeat this process for ten (10) more droplets that are at rest. It is Measure the radius of the drop recommended that this table be recreated in a spreadsheet utility like MS Excel or Google Sheets. The oil density is 900 kg/m^3 Data Table 1.
