Explain Earthquakes are natural disasters that occur when there is a sudden release of stored energy. The majority of earthquakes occur along a fault. A fault is a fracture within the earth. Earthquakes can be measured based on their magnitudes as well as their intensity; sometimes people get the two confused.
In a student experiment, a constant-volume gas thermometer is calibrated in liquid nitrogen (196°C) and in boiling allyl alcohol (97°C). Find what value of absolute zero does the calibration yield
At rest, a car's horn sounds the note A (440 Hz). The horn is sounded while the car is moving down the street, What is the speed of the car
Boat A negotiates a curve whose radius is 405 m. Boat Bnegotiates a curve whose radius is 150 m. Each boat experiences the same centripetal acceleration. What is the ratio of the speed ofboat A to that of boat B?
On a typical mission, the Space Shuttle (m = 2.00 106 kg) orbits at an altitude of 250 km above the Earth's surface. Find the speed of the shuttle in its orbit.
A 2.30-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.40sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 35.0 N/m.
a runner hopes to complete the 10000-m run in less than 30.0 min . after running at constant speed for exactly 27.0 min
A uniform solid disk of radius 1.60 m and mass 2.30 kg rolls without slipping to the bottom of an inclined plane. If the angular velocity of the disk is 4.82 rad/s at the bottom, what is the height of the inclined plane?
A piece of cheese with a mass of 1.30kg is placed on a vertical spring of negligible mass and a force constant k= 1600 N/m that is compressed by a distance of 16.2cm. how high does the cheese rise from this initial position
In a series RLC AC circuit, the resistance is 26.8, the inductance is 22 mH, and the capacitance is 21.4 μF. The maximum potential is 197 Volt, and the angular frequency is 636.62 rad/s. Evaluate the maximum voltage across the inductor
An oxygen molecule has a vibrational mode that behaves approximately like a simple harmonic oscillator with frequency 2.99 X 10^14 rad/s. Calculate the energy of the ground state
three charged particles are placed at the corners of an equilateral triangle of side 1.20. the charges are q1 6.7uc q2
The equation F = arv + br2v2 gives the magnitude of the resistive force (in newtons) exerted on a sphere of radius r (in meters) by a stream of air moving at speed v (in meters per second), where a and b are constants with appropriate SI units.
