Please answer ALL questions! Thanks in advance. Put the following equations into straight-line form. Assume for both cases that T is the dependent variable, and the L and r are the independent variables in and respectively. T = C Squareroot L/g T = 2 pi r^3/2/Squareroot G M_g I have a vector that is 15m in magnitude (|A|). It starts at the origin and is pointing 15 degree (Theta-A) above the x - axis. What are the x and y...

3 Students and a Textbook-Extended +X students converge on the last textbook in the store. All three grab it and begin to pull in the directions shown in the above figure. Student A exerts a force of 55.46 N, student B puils with a force of 17.30 N, and student C pulls with a force of 59.33 N at an angle 6(theta)-72.61 degrees above the -x axis. (The drawing is not to scale.) You want to determine the net force...

3. [Total: 8 pts) The purpose of this problem is to remind you of basic vector manipulation, and to get you familiar with the notation used in this class. Suppose a point charge q > 0 is at rest and located at position r = (2,3), in a two- dimensional Cartesian coordinate system (x,y). Suppose we want information about the electric field E at position r= (6,4). a) 2 pts) We will define the 'script-r' vector 1 =r-r'. Make a...
Write a C++ program that creates the following eight two dimensional random number vector: (a) the voltage vector V[][] contains n X m voltages between 100 and 1000 Volts, (where n.= #rows, m=# columns) (b) the current vector I[][] contains nXm currents between 10 and 50 Amps, (c) the phase vector PH[][] contains nXm phase angles between 0 and 45 degrees (d) The power vector (units of Watts) is given by: P[][] = V[][]*I[]*cos(PH[][]*M_P1/180); (e) The reaction vector (units of...
To understand two different techniques for computing the torque on an object due to an applied force.Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F⃗ lies in the xy plane, and this force of magnitude F acts on the object at a point in the xy plane. The vector r⃗ is the position vector relative to the pivot point p to the point where F⃗ is applied.The torque on the...
