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.
17.”Observing” the early Universe. The only way we have of studying the era of nucleosynthesis is through the abundances of the nuclei that is you left behind. Explain why we will never be able to observe of that era through direct detection of photons emitted at that time.

- See the screenshot uploaded. Answer in a step-by-step format, add diagrams, and detailed side notes for a better understanding. For a more clear response please answer on paper Thank you!arrow_forwardNeed help with prob 2. Please show your work and box your answer thank youarrow_forwardPlease answer using the variables provided and show explanations and work spaced out. I cannot understand when its all typed together. Please circle final answers for each of the three parts.arrow_forward
- 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_forwardHello, part D was incorrect, and where does the six come from?? I confused on reading the grapharrow_forwardWhat is the answer? Show your complete solution. Step-by-step. Provide the cases used. Simplify your final answer without the use of calculator.arrow_forward
- See the screenshot uploaded. Answer in a step-by-step format, add diagrams, and detailed side notes for a better understanding Ps. Please answer on paper Thank you!arrow_forwardPlease do all the parts, there are 2 total screenshots attached and 4 parts. DOUBLE AND TRIPLE check your answers the previous tutor got them all wrong.arrow_forwardWhy I got it wrong? Please help me to provide just few summary.arrow_forward
- Activity. Answer & sketch Give a brief yet concise answer to these two questions below and draw appropriate icons or images which will remind you of the concept. 1. How did Hertz discover radio pulses? 2. How does the theory of special relativity support the conflicting notions of Newton and Maxwell?arrow_forwardPlease explain it short and easy to understand (The picture is what the experiment look like) (Please don't explain it by giving the formulas because I don't understand) It is all related. What is the effect of increasing and decreasing the altitude where the experiment takes place? Why? (I really don't understand this question because it does not change anything when increase or decrease it) What is the effect of increasing or decreasing the mass of the cannon ball?(I think the effect is that with air resistance, increasing the mass will increase the range of the cannonball because the object is heavier. Is it correct?)arrow_forwardPlease write out our solutions clearly with all the steps, final answer, and units. Draw pictures and labeled diagrams.arrow_forward
