- (Thermodynamics) The work, W, performed by a single piston in an engine can be determined by this formula: W=Fd F is the force provided by the piston in Newtons. d is the distance the piston moves in meters. a. Determine the units of W by calculating the units resulting from the right side of the formula. Check that your answer corresponds to the units for work listed in Table 1.1. b. Determine the work performed by a piston that provides a force of 1000 N over a distance of 15 centimeters.arrow_forwardComputer Science Please help You went camping overnight but forgot to take with you a heater and need to make one using a dc battery of V0 and spare electrical wires of different lengths and resistivity. The battery has lead with the resistance of Rw. Please obtain the formula for the joule heat power and plot it as a function of RH ( in MATLAB) and in comparison to the resistance of the connecting leads, Rw. (Note: express RH = x Rw, where x is the effective ratio; vary x and plot Pmax vs. x). and Find the heating power if the heater is made out of superconducting metal. Will this heater work and why?!

In the descent phase of an extraterrestrial space mission, a spacecraft free falls through the planet's atmosphere. As it falls, it will reach a constant or terminal velocity when the air resistance force balances the gravitational attraction force. The terminal velocity is given by V₁ = where m is the spacecraft's mass [m], g is the acceleration due to gravity on the planet, p is the atmosphere's density [kg/m³], Cp is the spacecraft's drag coefficient, and A is the spacecraft's cross-sectional area [m²]. a) Write a function named terminalVelocity which calculates the terminal velocity an object. The function should . 2mg pCDA input m, g, p, CD, and A output the terminal velocity b) Write a program named q03.m which calculates the terminal velocity of a spacecraft at 10 km above the surface of various planets. The spacecraft's properties are m = 240 [kg], A= 15 [m²], and Cp = 0.5. The program should use the gravity and terminal…arrow_forward
- Suppose that a parachutist with linear drag (m=50 kg, c=12.5kg/s) jumps from an airplane flying at an altitude of a kilometer with a horizontal velocity of 220 m/s relative to the ground. a) Write a system of four differential equations for x,y,vx=dx/dt and vy=dy/dt. b) If theinitial horizontal position is defined as x=0, use Euler’s methods with t=0.4 s to compute the jumper’s position over the first 40 s. c) Develop plots of y versus t and y versus x. Use the plot to graphically estimate when and where the jumper would hit the ground if the chute failed to open.arrow_forwardA vertical tower stands on a horizontal plane and is surmounted by a vertical flag-staff of height 6 m.

If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots. Write a program Equation.java for solving a quadratic equation that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display two roots. If the discriminant is 0, display one root. Otherwise, display "The equation has no real roots". Note that you can use Math.pow(x, 0.5) to compute the discriminant. Here are some sample runs.
