Which of the following statements is/arecorrect? 1. The amplitude of the oscillations at any frequency decreases. 2. The maximum amplitude occurs at a lower frequency. 3. The peak on the graph becomes thinner. * O Statement 1 is only correct O Statement 3 is only correct O All three statements are correct. Statement 2 is only correct

LAB #6: SIMPLE PENDULUM STUDENT LEARNING OUTCOMES • Determine g, the acceleration due to gravity, using a pendulum. • Conduct a pendulum experiment using household items. After doing the experiment as it says in the lab and calculating all the data and answering all the questions please write a lab report. All the data and the tables should be in the report. Also, all the instructions in the lab report are clear. Please take pictures for your own experiment. Informal lab: Include a series of questions listed in the lab instructions, and images detailing your experiment tables, plots, or pictures). Questions are in bold and labeled with >Q#: You should write your an- answers so they work as standalone statements. For example: if the question asks "What is the force of tension?" your answer should read "The force of tension of a string with a 500 g weight hanging from it is 4.9 N "0.1 N," not "It is 5 N." One-word answers like "No" are not acceptable. LAB 3 REQUIRED FOR THIS IS ADDED IN REFERENCE SECTION. YOU NEED TO DO THE LAB FIRTS AND THEN MAKE A LAB REPORT

The temperature near the surface of the earth is 291 K. Anargon atom (atomic mass = 39.948 u) has a kinetic energy equalto the average translational energy and is moving straight up. Ifthe atom does not collide with any other atoms or molecules,how high up would it go before coming to rest? Assume that the acceleration due to gravity is constant throughout the ascent.h =.

(a) Choose relationship between the gravitational potential energy, Ep and the gravitational potential, V for a body of mass m placed in a gravitational field. and the mass of the Earth = 5.98 × 1024 kg. Find the radius of orbit A and of B from the centre of the Earth. RA = - RB = (c) Calculate the centripetal acceleration of a satellite in orbit

Let's recap what we've been learned from the previous tutorials: Use the information from the video to answer these questions: 1A) What is the period of a Cepheid star used to directly determine? 1B) How do the light spectra from far away stars compare to our expected spectra? 1C) Which is true about the red shift seen in the light from far away stars?

A planet of mass M and radius R rotates so quickly that material at its equator only just remains on its surface. What is the period of rotation of the planet? 2 \pi \sqrt{\frac{R^{3}}{G M}} 2 \pi \sqrt{\frac{G M}{R}} 2 \pi \sqrt{\frac{R}{G M}} 2 \pi \sqrt{\frac{G M}{R^{3}}}

Two ideal gases have the same mass density and the sameabsolute pressure. One of the gases is helium (He), and its tem-perature is 166 K. The other gas is neon (Ne). towhere the molar mass of helium and neon are given byMHe = 4.0026 kg mol- and MNeth= 20.179kgmol-1 What is the temperature of the neon?

The acceleration due to gravity at the north pole of Jupiteris 25 ms-2. Jupiter has a mass 1.9 x 1027 kg and radius7.1 x 107 m. (a) What is the gravitational force on a 5 kg object placed atthe north pole of Jupiter? (b) If the apparent weight of this mass placed at the equator(ie the push of the ground on this mass) is 113 N, calculate thelength of Jupiter's day. Assume Jupiter is spherical. (c) Calculate a value for G.
