Really need help with both please

u Question 43 2 pts rms The rms voltage across and the rms current through a single circuit element connected to an ac generator are, respectively, v = 109 volts and Irms = 39 A. The angular frequency of the generator id w = 60. It is observed that the current leads the voltage by 90°. The element that is connected to the ac generator is either a capacitor, an inductor, or a resistor (only one of the three). What is the resistance, or the capacitance (in uF ), or the inductance (in mH), of the element in the circuit (which ever it is)? Please round your answer to the nearest whole number (integer). Helpful equations that you may need (you need only one of the equations): V = IR, V=1XL, V = 1Xc XL =WL and XC 1 WC
Question 53 2 pts A concave mirror in an amusement park has a radius of curvature of R = 15.5 m. A child stands in front of the mirror so that she appears M= 5 times taller than her actual height (magnification). If the image is upright, how many meters is she standing from the mirror? Please round your answer to one decimal place. 1 R i Equation: + * = } f= M=- р 2 р Your task is to find the object distance, p.

Answers

• Vine = 109 valts, Irms=39A , W = 60radis current leads the voltage, it means circuit is capacitive Verms Vc = IX => Xc = Ve
