In 2019, Elaine paid $2,920 of tuition and $840 for books for her dependent son to attend State University this past fall as a freshman. Elaine files a joint return with her husband. What is the maximum American opportunity tax credit that Elaine can claim for the tuition payment and books in each of the following alternative situations? (Leave no...
On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 29 m/s at an angle 22 ∘ above the horizontal. How long was the ball...

A roller coaster starts from rest at a height h at the left side of a loop-the-loop, as shown in the figure. It is not attached to the track in anyway, and there is no friction from the track or from air resistance. If the radius of the loop is R = 6.0 m, what is the...
0.0301 8. The National Health Interview Survey reports that 29% of telephone users no longer use landlines, and have switched completely to cell phone use. Suppose we take a random sample of 17 telephone users. Find the probability that the sample contains exactly 9 users who have abandoned their landlines. Use the binomial probability formula. Write your answer rounded to...
A 1F capacitor is charged to full capacity by a 10V battery and disconnected. The capacitor is then discharged through a light bulb. Determine the initial brightness of the bulb (in watts) and find the time it takes for the bulb to fall to 1/e? of it's initial brightness for the bulb specifications given below. Assume that the brightness is...
Problem 5.1 Octane/Decane A liquid mixture containing 10.0 wt% n-octane and the balance n-decane flows into a tank mounted on a balance. The mass in kg indicated by the scale is plotted against time. That data fall on a straight line that passes through the points (t = 5.00 min, m : 125 kg) and (t=12.00, m : 231 kg)....
Sandy Carlson, who plays for her college basketball team, had an 80% free throw percentage in the previous fall semester. On average, Sandy made 8 out of every 10 free throws. If we are to randomly select 80 free throws she has made throughout the season and then record the number of successes in these 80 free throws, then the...

Name(s): the ripple voltage for the cir i) Approximate formulas for the peak rectifier (e.g., see the textbook). Assume the 0.7V diode; (ii) Transient simulation using Multisim with the IN5393GP diode. Show the output voltage plot. The circuit consists of a 5uF capacitor, IkOhm resistor, diode, and source. The source voltage is a periodic triangular waveform with the...
“Wine Balloon,” owned by Eric Corti, produces a wine-preserving product. The product currently sells for $22 and costs $6.50/unit when production is at 700 units. The sharks advise that the potential to cut costs are huge and hence increase revenue. If he produces 100,000 production cost per unit will fall to $2.50. That would be a $4/unit savings! 1) Calculate total...
A large weather balloon whose mass is 222 kg is filled with helium gas until its volume is 330 m3. Assume the density of air is 1.20 kg/m3 and the density of helium is 0.179 kg/m3 (a) Calculate the buoyant force acting on the balloon. (b) Find the net force on the balloon and determine whether the balloon will rise...
