Write a program to determine how long, in units of seconds, it will take a motor to raise a load into the air. Assume the user will specify the power of the motor in units of watts, the rated efficiency as a percentage (in whole number form — for example, 50 for 50%), the mass of the load in kilograms, and the height the load is raised in the air in units of meters. As a test case, you may assume the user provides 100 watts for the power of the motor, 60% for the efficiency of the motor, 100 kilograms for the mass of the load, and 5 meters for the height the load is raised.

- Using graphical method solve this problem: Suppose you first walk A in a direction of B west of north then C in a direction D south of west. You rest for 20 minutes and started to compute the distance you traveled. Take A, B, C and D found in the table below. (You may use scale such as 1cm = 2m in your drawing) C. What is the angle between AC ? D. What is the angle between your first walk A to the resultant R?arrow_forwardI was going over the equations for the notes in class and I had a thought. Based on the equations in the image, you could get negative propellant mass. So, I coded it in matlab and I got negative mass. How is that possible? I think I used practical values for the velocity and mass ratio and so on. Did I do something wrong?arrow_forwardSolve the following problems.Show your correct and complete solution for this problem. Box your final answers and express in two decimal places.Sketch the schematic diagrams. Initially, a rigid tank contains 500L of water at 300°C. By volume, the tank contains60% liquid and 40% vapor. At the bottom of the tank, as shown, a valve is opened and half of the mass of water is withdrawn which is in the liquid phase. Heat transfer takes place such that the temperature within the tank is constant. Determine the heat transfer in kJ required to withdraw half of its mass and maintain its temperature.arrow_forward
- JUST DRAW THE SCHEMATIC DIAGRAM. NO NEED TO SOLVE. THANK YOU In Rizal province, one of its power plants has been thoroughly monitored for possible conversion into a wind power plant. A propeller wind turbine is to be used. Survey showed that Rizal Province at a height of 10 meters above the ground has a minimum wind speed of 7.1 miles per hour duringthe month of June and a maximum wind speed of 12.9 miles per hour during the month of January. The minimum temperature is at 75 degree Fahrenheit during the month of January and maximum temperature is at 89 degree Fahrenheit during the month of May. The existing power plant has an output of 54MW. For the proposed wind power, the power coefficient of turbine is 35% and the generator efficiency is 95%. Theimpeller diameter is assumed not to exceed 90m. Determine the following:a. Theoretical Wind Power Outputb. Electrical Power Outputc. Number of turbines to be installedarrow_forwardA village of Pikachu and Psyducks was hit by a horrible storm. This village is surrounded by mountains and the only way out left is to cross a river. Imagine you are an engineer in a rescue team, and your team has decided to construct a temporary bridge over the river to rescue the villagers. The two bridge stones on both sides of the river have been built, and the river is 10 meters wide. All Pikachu and Psyducks weigh 6 kg and 20 kg, respectively. a) You have selected tempered glass with a facture strength of 120 MPa that has a width of 1 meter and enough length to build the bridge. The manufacturer now awaits your decision on the thickness of the glasses. If the maximum number of Pikachu and Psyducks simultaneously on the bridge is respectively 50 and 20, what is the minimum thickness in millimeters required for the safe crossing of the villagers? (Hint, you can assume all weights only exert a single force at the center of the bridge, don’t overthink this problem!) b) If the…arrow_forwardUsing graphical method solve this problem: Suppose you first walk A in a direction of B west of north then C in a direction D south of west.

IF ANSWER GUIDELINE I WILL DISLIKE OKK 1. height of sweet potato plants; 2. programable speed of a rover: . something that says that a rover is programmed via speed, that it doesn't matter if the weight of the rover is decreasing from time to time. something that says that if you programmed a rover to go 5kph it will remain 5kph even if you put something heavy on it.arrow_forward1. HI CAN YOU HELP ME WITH MY ASSIGNMENT. PLEASE WRITE IT PROPERLY, DONT WRITE IT. Faculty members and staff from ABC University had a meeting on how they will conduct the virtual flag ceremony every Monday. There are reported 12 faculty members, 3 office staff, 4 heads from the different courses and 1 student leader attended a secret meeting in a room which is 15 meters wide by 10.5 meters long and a ceiling of 3.87meters. The room is completely sealed off and insulated. Each persons gives off 150kcal per hour of heat and occupies a volume of 0.2 cubic meter. The room has an initial pressure of 14.696psi and temperature of 522.27 Rankine. • Calculate the room temperature after 15.5 minutes In Celcius • What is the mass of air in kilogramsarrow_forward
