in a simple nuclear reaction, for example the one I attached. Why is it that it creates oxygen and 1 proton instead of just F-18. (If you could explain it in simple english I would be so thankful)

1) Explain in your own words the 22 concepts shown in the concept map attached here. Try to explain a concept in one sentence if possible. Also, while explaining a concept, try not to bring-in another concept from mechanics. For example: “Mechanics: Mechanics is the domain of human knowledge that enables us to determine how … Read more

PART A The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered. For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned. To support your work, use your course and text readings and also use outside academic sources (no wikis, etc.). As in all … Read more

Hello I have two labs that I need completed for my physics class. you did very well on my last one so I was hopeful my you could help.  the labs are tedious  and online they require specific instructions

(a) Draw a sketch of the situation before the collision and after the collision (label everything).     (b) Total momentum is conserved. See equation lines 8.33 and 8.34 in section 8.4 as a guide. Substitute any known values and simplify the expression as much as possible.  (c) Label this result as Equation #1. (d) … Read more

Using a real-world example that relates to your major area of study or work experience, find at least two places where potential energy (PE) is added into the system to keep things in motion. Based on your observations, make an estimation of the energy that is being added into the system.

  Resources:   Problems: Question 1 (3points): Calculate the displacement and velocity at time of 0.500 s for a ball thrown straight up with an initial velocity of 15.0 m/s. Take the point of release to be  y0=0 Question 2 (3points): A projectile is launched at ground level with an initial speed of 50.0 m/s … Read more

Choose a real world situation, such as diving off a diving board, rocket propulsion, or birds flying, and select a motion within that situation that does not occur in a straight line, and is set in motion by the interaction of two objects. Motion that does not occur in a straight line indicates that more … Read more
