A steel cable with total length 31 meter and mass 150 kilogram is connected to two poles. The tension in the cable is 4,531 Newton, and the wind makes the cable vibrate with a frequency of 2 Hertz. Find the wavelength of the resulting wave on the cable.
A plan convex lens with radius of curvature R =3.4 m is in contact by a flat plate of glass. A light source and the observer's eye are both close to the normal, as shown in Figure 24.8a. The radius of the50th bright Newton's ring is found to be 9.1 m..
A 2000 kg sailboat experiences an eastward force of 3000 N by the ocean tide and a wind force against its sails with magnitude of 6000 N directed toward the northwest ( 45 degress N of W.) what is the direction of the resultant acceleration?
A 80-g bullet is fired from a rifle having a barrel 0.582 m long. Choose the origin to be at the location where the bullet begins to move. Then the force (in newtons) exerted by the expanding gas on the bullet is 14100 + 9100x - 24250x2, where x is i..
A screen is placed 1.84 m behind a single slit. The central maximum in the resulting diffraction pattern on the screen is 2.70 cm wide; that is, the two first-order diffraction minima are separated by 2.70 cm. What is the distance between the two sec..
as an admirer of thomas young you perform a double-slit experiment in his honor. you set your slits 1.07 mm apart and
