11 2:40l LTE Oum will oscillate S3 times every minute (1 minute 60 s en uniter. The length ofche pendulum rod is 0.8 m.a What is the period of the pendulum on Jupiter?N Determine the acceleration of gravity on Jupiter) What is the frequency of the pendulum on earth, where average value ofacceleration due to gravity is 9.81 m/s?d) Find the length of the pendulum rod, if we want to adjust the period of the pendumto 1.0 s.12. In the end-of-semester party, two powerful loudspeakers, placed next to each odher,playing music. Olivia is 13.0 m away from the speakers, and the sound level at her positionis 110 dB.a) What is the intensity of the sound at Olivia's position?b) What is the output power of the speaker?c) Determine the acoustic pressure received by Olivia, if the temperature is 30.0 "C andthe density of air is 1.22 kg/m'.d) Olivia's friend turns off one of the speakers (so the output intensity reduced to half ofthe original), what is the sound level hear by Olivia?13. A bat was flying toward a beetle at 34.6 m/s while emitted 90000 Hz ultrasound to the beetleto detect its location. The beetle was resting on a tree. The temperature is 23 "C.a) Find the wave length of the ultrasound emitted by the bat.b) Find the frequency of ultrasound wave received by the beetlec) Find the frequency of the ultrasound wave reflected back to the bat.d) After the bat caught the beetle, it's resting on a tree. A moth flying away from the batto escape. The bat emitted 90000 Hz ultrasound wave to the moth and received 77830Hz reflected back from the moth. Determine the speed of the moth.
