40. Bused on the figure, does S depend on the frequency of a sound wave of a given intensity? F. Yes, because as frequency increases. S increases. G. Yes. because as frequency increases. 5 remains con-tant. H. No, because as Irequency increases. S increases. J. No. because as frequency increases . S remains constant.

anvas Question 1 Aball with a mass of 2 kg tied to a rope is being swung around in the air at a speed of 4 m/s and the string length from hand to the ball is 2.1 m. What is the centripetal acceleration of speed of 4m/s the mass? square 10 pts

26. A4kg object is moving 2m/s to the right. A 6 N force pushes to the left for 3 seconds. A. Calculate Poefore. B. Calculate the impulse. C. What is Delta p for this object? D. What is its final momentum (p_(f))

Centripetal acceleration always points: C towards the center of the circle towards the outside of the circle in the opposite direction of the object's motion in the direction of the object's motion

in 1007, Albert A. Michelson and Edward W. Monley conducted an experiment to measure the speed at which the Earth moves through the either.Their experimen I was so reflied that is should have finally delected the funnistrous either. But it didn't. Repeated mais verified the surprising result that the ether did not exist. How did the failure of the Michelson-Moriey experiment change scientific theories of light? A. The results of the Michelson-Monley experiment did not fit the theory of the fuminiferous ether, so the theory had to be rejected B. The MichelsonMorley experiment provided a new theory that fit the data better than the theory of the fuminiferous ether did. OC. The results of the Michelson-Morley experiment had to be rejected because the theory of the fuminiforous other was so well established DD. The Michelson-Monley experiment proved that the luminiferous ether moved at the exact same speed as the Earth during all seasons of the year.
