The ultrasonic transducer used in medical ultrasoundimaging, is a very thin disk ( m =0.10g) driven back and forth in SHM at 1.0 MHz by an electromagnetic coil. The maximum restoring force that can be applied to the disk without breaking it is 40,000 N. What is the maximum oscillation amplitude that won't rupture the disk? What is the disk's maximum speed at this amplitude?
Find out the magnitude of the vertical component of the velocity
Using Newton's Version of Kepler's Third Law II Part A Pluto's moon Charon orbits Pluto every 6.4 days with a semimajor axis of 19,700 kilometers. Calculate the combined mass of Pluto and Charon. Express your answer using two significant figures. ..
You're driving down the highway late one night at 17 {rm m}/{rm s} when a deer steps onto the road 45 {rm m} in front of you. Your reaction time before stepping on the brakes is 0.50 {rm s} and the maximum deceleration of your car is 12 {rm m/s^2}..
At a right angle to a magnetic field. The acceleration of gravity is 9.81 m/s2. What is strength of the magnetic field necessary to exactly balance the weight of the proton and keep it moving horizontally.
Assume a 64 kg boy and a 42 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3 m/s2, find out the magnitude of the acceleration of the boy toward girl.
Light of wavelength 588 nm falls on a double slit. First-order bright bands appear 3.65 cm from the central bright band. The screen is 1.20 m from the slits. How far apart are the slits.
At what angle do the equipotentials intersect the edge of the conduction paper? why? Hint: the electric current flow at any point is in the direction of any directly proportional to the electric field vector.
A plane flies from base camp to Lake A, 300 km away in the direction 36.9° south of east. After dropping off supplies it flies to Lake B, which is 260km at 30.0° west of north from Lake A. find out the distance and direction from Lake B to the bas..
A car drives north at 48 for 10 and then turns east and goes 5 at 62 . Finally, it goes southwest at 24 for 6. Determine the cars displacement.
Suppose you hear a clap of thunder 15.80 s after seeing the associated lightning stroke. The speed of sound waves in air is 343-m/s, and the speed of light in air is 3.00x 10^8 m/s.
Write down your expression in terms of the dipole moment. Express your reply in terms of, and appropriate constants.
A planet of mass 6.00 1025 kg is in a circular orbit of radius 2.00 1011 m around a star. The star exerts a force on the planet of constant magnitude 5.03 1023 N. The speed of the planet is 4.09 104 m/s. All through this half "year", how much work is..
