"You have decided to use a specialized toy company to purchase birthday gifts for the young children of your friends and relatives. The toys you can choose are divided into three categories: plushies, blocks, and books. You can add a card and/or a balloon with each gift. Your program must print a title and a list of all the gifts to the console, with a total for each gift, and the total amount of the order. Your program must generate a random five-digit number to serve as the order number, followed by your name as programmer. The Toy class provided, will keep a total cost for one toy and determine if the toy is age-appropriate for the child. You should not make any changes to the Toy class. Assume that the user enters the name and age of the child correctly."

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
