Question 5 a) The rest mass of the T, and π meson are the same, but...
plz help´д` The lifetime of a particular meson at rest is 10-8 second and its mass is 10-25 gram. If its velocity in the laboratory is 2*108 meters per second, how far will it travel in one lifetime, if both distance and lifetime are measured in the laboratory frame?
a)Determine the phase constant ϕ (−π≤ϕ≤π) in x=Acos(ωt+ϕ) if, at t=0, the oscillating mass is at x=A. b)Determine the phase constant ϕ (−π≤ϕ≤π) in x=Acos(ωt+ϕ) if, at t=0, the oscillating mass is at x=1/2A. c)Determine the phase constant ϕ (−π≤ϕ≤π) in x=Acos(ωt+ϕ) if, at t=0, the oscillating mass is at x=−1/2A. d)Determine the phase constant ϕ (−π≤ϕ≤π) in x=Acos(ωt+ϕ) if, at t=0, the oscillating mass is at x=A/√2
At t = 0, a 795 g mass at rest on the end of a horizontal spring (k = 125 N/m) is struck by a hammer, which gives it an initial speed of 2.77 m/s. (a) Determine the period of the motion. (give answer in s) Determine the frequency of the motion. (give answer in Hz) (b) Determine the amplitude. (in m) (c) Determine the maximum acceleration. (in m/s2) (d) Determine the position as a function of time. give answer in...
is the first one right? please help with 13 A simple pendulum (mass on a string) oscillates with a period T. The mass is then doubled. The period is now: T/4 O 2T OT O 4T T/2 Question 13 8 pts An object completely submerged in an incompressible fluid is at rest. Which of the following are true? (Select all that apply.) If the object is pushed slightly downwards it will keep moving downwards with constant velocity If the object...
Using Excel, plot the function f(t)=3*cos(500*π*t) + 5*cos(800*π*t) from 00025 to .1s at .0025s intervals. Connect the points with straight lines. Explain the shape of the resulting plot. Find the FFT using Microsoft Excel.
5. Use the same mass, damping coefficient, and spring constant as in #4. a. The mass is pulled down 5 cm from rest and just released. Determine the IVP describing the motion of the mass. (6 pts) b. Solve the resulting DE from part a. (6 pts) c. Sketch the graph of the motion. (4 pts) 6 6.Again use the same mass, damping coefficient, and spring constant as in 4. a. Now the mass is pulled down 5 cm from...
Two protons (rest mass M = 1.67 * 10^-27 kg) move at same speed in opposite directions. After bumping into each other the protons remain, but as a consequence of the bump a new particle is created, which has a rest mass m = 1.75 * 10^-28 kg. a) Calculate the protons' speed at the beginning by assuming that all particles are in rest after the bump. Give your answer in the unit light speed c. b) Calculate the proton's...

Question 13 8 pts An object completely submerged in an incompressible fluid is at rest. Which of the following are true? (Select all that apply.) The mean density of the object is the same as that of the fluid If the object is pushed slightly upwards it will slow down until it comes to rest If the object is pushed slightly downwards it will keep moving downwards with constant velocity If the object is pushed slightly downwards it will slow...
only the last question plz 2. Let S be a set and let ~ be an equivalence relation on it. Let π denote the canonical projection, T: S → S/ ~, π(x) = [x] . Prove that π is an onto map. Give an example of a set and relation for which π is not one-to-one. What is the necessary and sufficient condition on ~ for π is one-to-one? (State your answers and prove them 2. Let S be a...
