I Review | C A solid conducting sphere of radius R carries a charge Q. Calculate the electric-field energy density at a point a distance r from the center of the sphere for (a) r < Rand (b) r> R. (c) Calculate the total electric field energy associated with the charged sphere. (d) How much work is required to assemble the charge Q on the sphere? (e) Use the result of part (c) to find the capacitance of the sphere. (You can think of the second conductor as a hollow conducting shell of infinite radius.) (Figure 1) • View Available Hint(s) O C= 4rEnR, so the capacity won't change. O C= 00 O C=0 4тертать where ra is an inner radius, rp is an outer radius. ть — га Submit Previous Answers All attempts used; correct answer displayed The capacity won't change; the only change will be in the electric field. We can consider that sphere as a spherical capacitor with inner radius R and outer radius tends to infinity Part H Find the potential difference between the charged sphere and infinity from C = Express your answer in terms of some, all, or none of the variables Q, en, R, and n.

Must solve the question completely. Don't solve partially. Skip it pls if u don't want to solve it completely. You must solve the complete question all 6 parts. Otherwise you can skip and let others solve it. But don't solve it partially one or three questions. If you do it, I will dislike for sure.

hat number w.ww The word "units" refers to the corresponding quantity of something. For example, 2 is a number; 2 seconds is a physical quantity that has the units of second. In physics problems, are usually not looking for a number; we are looking for a need to also know the units. If you do not include units with the answer, you will not receive physical quantity, which means we full credit. Physicists are very nitpicky about this! 8. You may have learned the formula distance speed x time. How long would it take in seconds to travel a distance of 2000 meters if you are traveling at a speed of 25 meters per second? (note: your answer must include the word "seconds" or the abbreviation "s" after your number...remember your units! \Sxt t1475 2000 25tt 2000 -25t 1975-t 9.

Hi I am currently struggling with Extra 1 and Extra 2

I cant get it right, both answers below are incorrect. I need(a) and (b).

1. List down three factors that would affect the human reaction time in general. 2. Explain how your reaction time would change if this experiment was conducted on the moon. 3. Explain how your reaction time would change if the mass of the ruler was doubled.

Hello, I just need help with part A thank you very much
