Pls help with these two questions i only have 20 mins

QUESTION 4 You look down and see a loop of wire on a tabletop. A machine inside the table produces a constant magnetic field that points straight up out of the surface of the table. After a moment, the machine kicks into gear and causes this magnetic field to increase in magnitude. Which of the following describes the current induced in the wire loop (from your perspective)? The current is clockwise at first, and then it switches to counterclockwise. he It flows in a counterclockwise direction. There is no induced current. The current is counterclockwise at first, and then it switches to clockwise. It flows in a clockwise direction. QUESTION 5 Sound resonates in a tube that is open on each end with a fundamental frequency of 300 Hz. If you were to close one end of the tube, what would the new fundamenal frequency be? 300 Hz 150 Hz 600 Hz 450 Hz
