Can u answer these asap please

Extracted text: The figure shows the circular wave fronts emitted by two sources, the wavelength for both idential waves is 1.3 m. What is the path-length difference at point Q, in meters? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed, Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.


Extracted text: For the circuit shown, AVbattery = 20 V, R1 = 3.0 Q, R2 = 2.0 Q and C = 4 F. The capacitor is initially uncharged and the switch is open. What is the charge on the capacitor a long time after the switch is closed, in Coulomb? Your answer needs to have 2 significant figures, including the negative sign inyour answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. R1 ww R2 3 C.
