S and P waves from an earthquake travel at different speeds and this difference helps in the determination of the earthquake "epicenter", (where the disturbance took place). (a) Assuming typical speeds of 9.0km/s and 5.5 km/s for P and S waves, respectively, how far away did the earthquake occur if a particular seismic statio

On a rather cold and rainy day we observed that the wind was blowing from the NE and the waves were traveling in all directions. Why would this be?
A particle of unit mass moving on the x axis has equation of motion (FUNCTION1) and the initial conditions are (FUNCTION2). show that (FUNCTION3) and deduce that the motion is an oscillation between x=1 and x=3 with period (FUNCTION4). By making the substitution (FUNCTION5) or otherwise show that (FUNCTION6). (PLEASE SEE ATTA

Hi. Can someone please help me with this conceptual question? An inductor and a capacitor are to be connected to a generator. Will the generator supply more current at a low frequency if the inductor and capacitor are connected in series or in parallel? Thank you.

A simple pendulum consists of a small marble suspended from nail #1 by a cord whose length is 12 m. Nail #1 is 6 m below nail #1, so that as the pendulum swings, the cord is caught on nail #2 when the cord is vertical. The marble is pulled a small distance from center and released at rest. see ATTACHMENT for a diagram of the e

In an assembly operation, a robot moves an object first straight upwards and then to the east, around an arc forming on quarter of a circle of radius 4.80 that lies in an east-west vertical plane. The robot then moves the object upward and to the north, through a quarter of a circle of radius 3.70 cm that lies in a north south

A mass sits on a frictionless table. It is attached to a wall by a spring. The mass is initially located at x = 0 when the spring is unstretched (equilibrium position). You pull the mass away from the equilibrium position, out to x = A, and then release it. The mass then oscillates horizontally back and forth in simple harmonic
