At time \( t \), in seconds, the position, in meters, of a particle moving along the \( x \)-axis is \( x(t)=t^{5}-2 t \). Assume for all parts of this problem that \( t \geq 0 \). a) Find the particle's acceleration whenever the velocity is zero. Acceleration when velocity is zero: \( \square \) b) Find the velocity of the particle whenever the acceleration is zero. Velocity when acceleration is zero: \( \square \)

QUESTION 3 A weightless source of 239Pu will be measured using a gas proportional counter (GPC). The GPC gross counting efficiency for this source is 0.388 counts per decay. The GPC background counting rate was determined to be 1 cpm for a background counting interval of 30 min. If the 239Pu source activity is 0.01 Ci, then how long should this source be measured such that the Poisson variance in the net counting rate is minimized? A. 289 min B. 577 min C. 789 min D. 1,250 min E. 2,784 min QUESTION 4 For a 5 minute counting interval of a long-lived radioactive source, 5,376 gross counts were recorded using a detection system with a gross counting efficiency of 0.023 counts per decay. For a separate 10 minute background counting interval, the background counting rate was determined to be 65 cpm for this detection system. If Poisson variance is assumed, then what is the 68% confidence interval for the source activity? A. 0.942+/-0.143 uCi B. 0.942+/-501 uCi C. 0.942+/-0.221 uCi D. 0.942+/-0.0014 uCi E. 0.942+/-0.0003 uCi QUESTION 5 The following information applies to Problems 5 – 7. A sample containing 3.75 min 52V was measured for 5 minutes and 1,084 gross counts were recorded using a given detection system. The counting interval was started at 12:00 pm. For a separate 15 minute background counting interval, the background counting rate was determined to be 54 cpm for this detection system. 5) What was the net counting rate at 12:00 pm (i.e., at the beginning of the counting interval)? A. 249.5 cpm B. 642.6 cpm C. 2,374 cpm D. 4,913 cpm E. 5,430 cpm

Calculate Bond Price: In reference to the problem above, if the borrower (corporation) has financial issues and the company gets downgraded by rating agencies (like Moody's or Fitch) and the YTM goes up to 6%. Calculate the price of the bond with this higher risk situation (hence higher YTM). Calculate expected rate (Yield to Maturity): Bond Price: 900 N = 10 years Coupon rate: 6% (Annual payments) Par Value: 1000 YTM: ? (Hint: Use "RATE" from Excel financial formulas)
