Q. The acoustical system is driven by speaker emitting a 432Hz note. If destructive interference occurs at a particular instant, by what least amount amount must the difference of two path lengths in the U-shaped tube be increased so as to hear constructive interference?
Q. A crate of mass 14.00 kg is pulled up a rough incline with an initial speed of 1.50 m/s. The pulling force is 100 N parallel to the incline that makes an angle of 19.50° with the horizontal. The coefficient of kinetic friction is 0.40, and the crate is pulled 5.25 m.How much work is finished by gravity?
use the inverse square law to display that in space shuttle territory, 200 kilometers above earth's surface, the force of gravity on a shuttle is about 94 percent of that at earth's surface.
The two parallel plates in the figure below are 2.0 cm apart and the electric field strength between them is 2.1 104 N/C. An electron is launched at a 45° angle from the positive plate. What is the maximum initial speed v0 the electron can have witho..
Keeping a constant speed of 0.6 m/s, a marble of mass 18 g rolls back & forth across a shoebox that is 14 cm high & 2 mm thick. Estimate the probability of its escaping through the wall of the box by quantum tunnelling.
Two equally charged, 1.00 {rm g} spheres are placed with 2.00 {rm cm} between their centers. When released, each begins to accelerate at 225 {rm m/s^2}. What is the magnitude of the charge on each sphere.
A horizontal force of 213 N is exerted on a 1.90 kg discus as it rotates uniformly in a horizontal circle (at arm's length) of radius 1.60 m. determine the time for one revolution of the discus. Round the answer to 2 decimal places.
IP A uniform electric field of magnitude 6 times 10^3 ;{rm{N/C}} points upward. An empty, closed shoe box has a top and bottom that are 37 cm by 28 cm, vertical ends that are 28 cm by 21cm, and vertical sides that are 21 cm by 37 cm.
A production line inspector wants a mirror that produces an upright image within magnification of 7.4 when it is located 15 mm from a machine part.
A magnetic field near the ceiling points up and is decreasing. Looking up at the ceiling, does non-Coulomb electric field curl clockwise or counter-clockwise.
