Can you plzzzzzz do all 3 plzz ### Question 7:A spring with spring constant \( k \) hangs vertically. Fermina hangs a mass from the spring and displaces it from its equilibrium position so that it oscillates up and down at a frequency \( f \). She then removes this mass and replaces it with a mass four times the mass of the original one and sets it to oscillate again. What will the frequency be now?**Options:**- A. \( f/2 \)- B. \( 4f \)- C. \( f/4 \)- D. \( 2f \)The correct answer is not marked, but the following multiple choice options are available:- B (unselected)- C (unselected)- D (unselected)- A (unselected)### Question 8:1 pointThe period of a simple harmonic oscillator is 0.04 s. What is its angular frequency?**Options:**- A. \( 25\pi \) rad/s- B. \( 50 \) rad/s- C. \( 50\pi \) rad/s- D. \( 40\pi \) rad/sThis question also appears with the multiple-choice options unselected and each choice follows the typical format of angluar frequency given a period. Pendulum A has length \( L \) and a bob of mass \( M \) at its end. Pendulum B has length \( L/4 \) and a bob of mass \( M/9 \) at its end. If both pendulums are set in motion with small amplitude oscillations, what is the ratio of their frequencies \( f_A/f_B \)?A. \( 2/1 \) B. \( 1/4 \) C. \( 1/2 \) D. \( 2/3 \)

Let initial mass =m Therefore, the replaced mass will be =4m
