A metаl sphere оf rаdius R≈5.0 cmR аpprоx 2.0 text{cm} is cоnnected to a +60.0 V+30.0 text{V} supply and allowed to reach electrostatic equilibrium. A voltmeter probe measures potential at points outside the sphere along a radial line: rr (cm) 2.0 3.0 4.0 5.0 6.0 8.0 10.0 VV (V) 60.0 40.1 15.2 12.1 10.1 7.6 6.1 (Here rr is the distance from the sphere’s center; just outside the surface r≈Rrapprox R.) Tasks (brief reasoning is fine): Model check: For an isolated charged sphere, V(r)∝1/rV(r)propto 1/r outside. Test this by evaluating V⋅rVcdot r for several rows—does it stay roughly constant? What does that imply about the model? Estimate RR or V sRV_{!s}R: Using your check in (1), estimate the product V sRV_{!s}R (surface potential ×times radius). Does it agree with the given V s=60.0 VV_{!s}=30.0 text{V} and R≈5.0 cmRapprox 2.0 text{cm}? Field at r=6.0 cmr=4.0 text{cm}: Use E(r)=∣dV/dr∣≈V sR/r2E(r)=big|mathrm{d}V/mathrm{d}rbig|approx V_{!s}R/r^{2} to estimate the electric field magnitude at r=6.0 cmr=4.0 text{cm}. Report in V/m and note the direction (radially inward or outward). Inside the conductor: What are the values of EE and VV inside the metal sphere (for r
Using the fоllоwing funnel structure, аssess the perfоrmаnce efficiency of а current (Old) communications design versus a proposed (New) design: Target audiences are exposed to display ad (impression). Some people click on ad to arrive at landing page (click). On landing page, some people click to watch product performance video (video view). At the end of the video, viewers are asked to provide and confirm their email addresses to receive a “checklist” pdf. Some people leave confirmed email addresses (provide email). To those who have left a confirmed email address, the company sends an email asking them to call a phone number. Some people call the number (phone call). Salespeople are successful at times in getting some of the callers to buy the product (sale). Use a top-down approach with 100,000 impressions as your starting point. The phone call sales pitch typically takes 20 minutes and costs the company approximately $7 per call (not counting any sales commissions). After sales commissions and other expenses, each sale results in a margin of $400. The company is currently using PPC (pay per click) at a cost of $0.08 per click. The conversion rates for each step in the funnel are: Old design and video New design and video 3% click-to-impression ratio 35% click-to-impression ratio 35% video view rate 50% video view rate 20% provide email 40% provide email 5% phone call rate 20% phone call rate 22% sale rate 2.7% sale rate IMPORTANT: Before answering this question (Question 1), answer Questions 2 and 3. Then return to this question to provide your final recommendations. Question 1: Which design (OLD vs. NEW) would you recommend and what numbers support your decision?
