7. During a wind storm, two guy wires supporting a tree are under tension. One guy wire is inclined at an angle of 35" and is 40 135 under 500 N of tension. The other guy wire is inclined at 40 to the horizontal and is under 400 N of tension. Determine the magnitude and direction of the resultant force on the guy wires.8. Dot products can he used to calculate the average power requirements of appliances that run on alternating current, including man3r home appliances. The power, P, in watts, required to run an appliance is given by the formula P=VIeosEi, where Via the voltage, in volts; 1' is the current, in amperes; and B is the phase angle between the voltage and the current. a} Write this formula as a dot product. h} An electric motor is connected to a IIil-v' AC power supply and draws a current of A with a phase angle of 15'. What is the average power rating of the motor
