Implications 1. An electric heater supplies 18 kJ of heat energy to a metal block of mass 0.5 kg. The temperature of the block rises from 20 °C to 100 °C during the heating process. Assuming that no heat is lost from the block during heating, determine the specific heat capacity of the metal. Show your working.

A force of (2.0 i - 3.0 k) N acts on a 0.80-kg particle which is located at (0.50 j - 2.0 k) m relative to the origin. The velocity of the particle is (5.0 i - 6.0 j) m/s. Relative to the origin, what are the particle's angular momentum, the torque acting on the particle, and the rate at which the angular momentum is changing?

Where necessary, show all work for credit. 1.8 points] Residual plots are provided below for two different regressions. Which one of them shows greater evidence of violating the assumptions of regression and why. Discuss the specifics of any over- or under-prediction or heteroscedasticity for the regression that you choose. You are to only discuss one regression.

Using Mips32/Mars. Also please do not give me the code for calculating the Area of circle, square, and rectangle. This is not the objective. The only thing that needs to be computed/displayed is the surface area for a sphere and a cube. 1. Write an assembly language program that prompts the user for and reads four integers (x1, y1, x2, y2) which represent the coordinates of two points. Make sure you keep track of which number is which. 2. Treat the line between the points as the radius of a sphere and compute the surface area of the sphere. Print the output with a label, such as "The surface area of the sphere is: .. Hint: The distance between the points is the square root of ((x2 - x1)^2 + (y2 - y1)^2). However, since you have to square the radius to get the area, you don't need to worry about calculating the square root. Just use ((x2 - x1)^2 + (y2 - y1)^2) in place of r^2. To work with t, do what the textbook does on page 14. Use 314159 as t and do the calculations. At the end, divide by 100000 and the quotient is your answer. Note that the answer will be an integer, which is fine. Formula: Surface Area = 4tr^2 3. Once part 2 is working properly, add code to treat the line between the points as the side of a cube and compute the surface area of the cube. The calculation is similar to what you did in part 2 except for the multiplication by n. Print the output with an appropriate label. Formula: Surface Area = 6 * side^2 4. Add labels above each of the calculation code segments such as (sphere:) and (cube:). Add a menu to the program that prompts the user as follows: "To quit enter 0" "To calculate the surface area of a sphere enter 1" "To calculate the surface area of a cube enter 2" "Enter your choice:" If the user enters 0, the program terminates. Otherwise, the user enters the four values and you branch to the correct calculation area and output area. This may require several branching instructions. Once a calculation is made, you loop back to the menu. 5. Test the problem with the following data: x1: 1, y1: 1, x2: 3, y2: 3, Surface area of sphere: 100 x1: 20, y1: 30, x2: 40, y2: 50, Surface area of sphere: 10053 Surface area of cube: 48 Surface area of cube: 4800
