A 0.30 kg mass is suspended on a string. In equilibrium the mass stretches the spring 2.0 cm downward. The mass is then pulled an additional distance of 1.0 cm down and released from rest.
(a) Calculate the period of oscillation.
(b) Calculate the total energy of the system.
A pot containing 1.01 liter of water, initially at 19°C, is placed on a 1051 W electric heating element. How much heat is necessary to boil all the water away
James bond (mass 78 kg) is running to catch a bag (mass 23 kg) containing an antiserum to a deadly disease. Initially Mr. Bond is running 4.4 m/s north and the bag is travelling 2.9 m/s east. What is the final velocity (magnitude and direction) of Ja..
A steel cable with total length 59 m and mass 110 kg is connected to two poles. The tension in the cable is 1,260 N, and the wind makes the cable vibrate with a frequency of 2 Hz. Calculate the wavelength of the resulting wave on the cable
A sinusoidal wave traveling on a string has a period of 0.21s, a wavelength of 32cm, and an amplitude of 5.0cm. compute the speed of this wave
Two ants race across a table 62.0 cm long. One travels at 4.69 cm/s and other at 3 cm/s. When the first one crosses the finish line, how far behind is second one? Reply in units of cm.
Now, as both pipes vibrate at their fundamental frequencies, the beat frequency of 17 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 333 m/s.
The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons.
A circular loop of wire having a radius of 6.0 cm carries a current of 0.14 A. A unit vector parallel to the dipole moment of the loop is given by 0.40i -0.92j, Find the magnetic potential energy of the loop
How much energy is emitted by the blackbody, How much energy is emitted by the blackbody at all wavelengths in one hour
A large air conditioner has a resistance of 7.0?and an inductive reactance of 17?. Find the impedance of the air conditioner
The mass then travels vertically and it takes 1.10 s for the mass to reach the top of its trajectory. Determine the spring constant, in N/m. (Use g=9.81 m/s2). Assume that the time required for the spring to reach its full extension is negligible.
A jet aircraft is flying at constant altitude. At t1 = 0 it has components of velocity vx = 150 m/s and vy = 130 m/s, What is the acceleration's magnitude and direction during this time interval
