Q1. Two ocean liners, each with a mass of 40,000 metric tons, are moving on parallel courses, 92 m apart. What is the magnitude of the acceleration of one of the liners toward the other because of their mutual gravitational attraction? Treat the ships as particles.
Q2. A transverse wave on a cord is given by y(x, t) = 0.12 sin(3.0 x - 15.0 t), where Y, and x are in meters and t is in second. At t = 0.20 s, what are the displacement and velocity of the point on the cord where x = 0.60 m?
What is speed of the wind what is coefficient of static friction
Study of the fragment
Suppose that the light is incident at right angles to the film. what is the minimum distance from the slits to the screen when 580 nm light is used.
A 2.0-C charge moves with a velocity of (2.0i + 4.0j + 6.0k) m/s and experiences a magnetic force of (4.0i - 20j + 12k) N. The x component of the magnetic field is equal to zero. Find out the y component of the magnetic field.
The change in the kinetic energy of the system
What is the amplitude of subsequent oscillations
A 4.70 kg mass causes a vertical spring to stretch 0.850 meters. The spring is after that stretch and extra 0.270 meters and release (as a stopwatch starts) causing the spring and mass to oscillate.
With what tension should a rope with length 3.00m and mass 0.135kg be stretched for transverse waves of frequency 43.0Hz to have a wavelength of 0.720m. What torque does friction exert even as this wheel is slowing down.
