Marcel is helping his two children,
Jacquesand Gilles, to balance on a seesaw so that they will be able
tomake it tilt back and forth without the heavier child,
Jacques,simply sinking to the ground. Given that Jacques, whose
weight is, is sitting at distance to the left of the pivot, at what distance should Marcel place Gilles, whose weight is , to the right of the pivot to balance the seesaw?

Consider the following utility function of 3 goods, x, y and z: U(x,y,z)=ax+by+cz; x,y,z≥0 and a, b, c are constants. The prices of good x and y is denoted by pX and pY respectively. The income is denoted by m. Good z is provided by the government free of cost but the quantity of good z provided by the government depends on the consumption of good x and y chosen by the consumer. For example, if in equilibrium, the consumer...

Given three floating-point numbers x, y, and z, output x to the power of z, x to the power of (y to the power of z), the absolute value of (x minus y), and the square root of (x to the power of z). Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f} {:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3, your_value4)) Ex: If the input is: 5.0 1.5 3.2 Then the output is:...

Question 18 2 pts Three wires (X, Y, Z) each of length 1.6 m are lined up (like fence posts) in a row with wire Y midway between wires X and Z. Wire X has a current of 3.0 A toward the ground, wire Y has a current of 1.0 A toward the ground, and wire Z has 9.0 A toward the ceiling. If wires X and Z are 80.0 cm apart, what is the net magnetic field strength due...
