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.
Universe on a Balloon. In what ways does the surface of a balloon offer a good analogy to the universe? In what ways it this analogy limited? Explain why a miniature scientist living in a polka dot on the balloon would observe all other dots to be moving away,with more distant dots moving away faster.

- Write solution detailed solution (Given, Unknown, Formula, Step-by-Step Solution). Box your final answer. Please make sure that your handwritten is readable. Thank you.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_forwardUse a sketch, an equation in addition to your precise and concise description.

- Read the following questions carefully and answer the problems using GRESA. 1. Assuming that the field of view is flat, what is the resultant vector (yellow line) of an observer pointing his telescope starting at the Andromeda galaxy, then moving 62 units 27° S of W to Jupiter, then finally moving to Saturn 17 units 72° S of W. Express your magnitude to the nearest hundredths units, and the angle to the nearest hundredths °, following the standard cartesian plane coordinate system.arrow_forwardA balloon, in the shape of a right circular cylinder, is being inflated in such a way that the radius and height are both increasing at the rate of 3 cm/s and 8 cm/s, respectively. What is the rate of change of its total surface area when its radius and height are 60 cm and 140 cm, respectively?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.

- ONLY ANSWER 3 AND USE OTHER QUESTIONS FOR CONTEXT Suppose we have two sources of light, a deep red one with wavelength 700 nm, and a violet one with wavelength 400 nm. Both produce the same optical power, delivering 1 milliwatt (10−310−3 watts) of energy per second per square centimeter to a metal target with an area of 1cm2 located 1 meter from the sources. 1. Which color would deliver more photons each second? All the photoelectrons that are produced from the light are presumed to be collected by another electrode and we determine the current in amperes using a circuit and an "ammeter", that is, some device that can give a precise quantitative measure of the current. Such a device might use the magnetic field generated by the current, or the voltage produced when the current flows across a resistance. 2. If the work function of the surface is 2 eV, will we see a current with both colors, one color, or neither one? If so, how much (in amperes), or if not, explain. 3. If we now…arrow_forwardUse GFSA (Given, Find, Solution, and Answer) on the given space below. Encircle your final answer, write it in scientific notation with 2 decimal places. 1. What is the power input to an electric heater that draws 4 A from a 140-V outlet? 2. If R1 = 2Ω, R2 = 4Ω, R3 = 6Ω, determine the electric current flows in the circuit below using Kirchhoff’s law.arrow_forwardbox the finals answers.
