just tell the right options for this one

43 TUTU measure a spherical wave to have an intensity of 100 W/m z when it is 4 m from a source. What would be the intensity 2 m from the source? O A- 400 W/m2 O B. 200 W/m2 O C- 50 W/m2 O D. 100 W/m2 O E. 25 W/m2 44 TUTU sets up the circuit shown below using 4 pF capacitors. TUTU then measures the capacitance between point A and B. What would the capacitance TUTU measured be? C = 4 UF A C = 4 UF C = 4 UF B C = 4 UF O A. No answer is correct O B. 1.6 PF O C. 10 PF O D. 1 UF E. 0.63 UF
