There are competitions in which pilots fly small planes low over the ground and drop weights, trying to hit a target. Part A A pilot flying low and slow drops a weight; it takes 2.2 s to hit the ground, during which it travels a horizontal distance of 190 m. Now the pilot does a run at the same height but twice the speed. How much time does it take the There are competitions in which pilots fly small planes low over the ground and drop weights, trying to hit a target.

4-4. In a lie-detector test, an individual answers a series of questions, while connected to a polygraph (lie detector). This instrument measures and records several physiological responses of the individual on the basis that false answers will produce distinctive measurements. Assume that 99 percent of the individua who go in for a polygraph test tell the 4-4. In a lie-detector test, an individual answers a series of questions, while connected to a polygraph (lie detector). This instrument measures and records several physiological responses of the individual on the basis that false answers will produce distinctive measurements. Assume that 99 percent of the individua who go in for a polygraph test tell the truth. These tests are considered to be 95 percent reliable. In othe words, there is a 95% chance that the test will detect a lie if an individual actually lies. Let there also be 0.5% chance that the test erroneously detects a lie even when the individual is telling the truth. An individual has just taken a polygraph test and the test has detected a lie. What is the probability that the individual was actually telling the truth?

(Hint: Use the annual U.S. energy consumption to find the energy consumption per minute, and then divide by the energy yield from fusing 1 liter of water to figure out how many liters would be needed each minute.) Express your answer in liters per minute using two significant figures. PO AE O 31 ? 1/inin Submit Request Answer

Cash Register Assume that a local event coordinator asks you to write a Java application (CashRegister.java) to accept an event reservation with a payment option as cash only. This application must allow a clerk to enter the required information and display output for the reservation details. It must also enable the clerk to enter an amount of cash recelved Cash Register Assume that a local event coordinator asks you to write a Java application (CashRegister.java) to accept an event reservation with a payment option as cash only. This application must allow a clerk to enter the required information and display output for the reservation details. It must also enable the clerk to enter an amount of cash recelved and display a change amount. Required Information a. Customer's name, which includes both first name and last name b. Date of reservation c. Number of tickets purchased d. Cash Received (After balance due is shown) The cost per one ticket is \( \$ 25.50 \). The total price of the ticket purchased must include a sales tax of 7\%. After a clerk enters all information, the program will calculate a balance due for the customer. Then it must allow the clerk to enter an amount of cash received from the customer, which will calculate the change amount returned to the customer.
