Students use a simple pendulum with a length of 36.90 cm to measure the acceleration of gravity at the location of their school. If it takes 12.20 s for the pendulum to complete ten oscillations, what is the experimental value of g at the school?
Answer to relevant QuestionsThe equation of motion of a particle in vertical SHM is given by y = (10 cm) sin [(0.50 rad/s)t]. What are the particle’s (a) Displacement, (b) Velocity, and (c) Acceleration at t = 1.0s? The motion of a particle is described by the curve for System A in Fig. 13.25. (a) Write the equation of motion in terms of a sine or cosine function. (b) If the spring constant is 20 N/m, what is the mass of the object? The frequency of a simple harmonic oscillator is doubled from 0.25 Hz to 0.50 Hz. What is the change in its period? The speed of longitudinal waves traveling in a long, solid rod is given by v = √Y/p, where Y is Young’s modulus and is the density of the solid. If a disturbance has a frequency of 40 Hz, what is the wavelength of the ...Apiece of steel string is under tension.
