A box is moving with an initial velocity v = 25 m/s. If the coefficient of kinetic friction between the floor and the box is μ = 0.3how far will the box travel before coming to rest?
Please explain o
Consider a small, conducting sphere of 0.0010 kg mass. Extra electrons are added to
this sphere and an identical sphere below it so that the excess charge on the top sphere is three times that on the
As in the circuit sketched below, 8.00 ! and 2.00 ! resistors are connected to a
6.00 volt battery.
What is the power delivered by the battery in this circuit?
a. one-half watt or less
b. 0.600 W
c. 3
A capacitor consists of a conducting sphere of radius a surrounded by a concentric conducting shell of radius b. Show that its capacitance is C=[ab/k(b-a)].-You begin by assuming theres some charge Q
A sphere of radius R carries a nonuniform but spherically symmetric volume charge density that results in an electric field in the sphere given by E=E_0(r/R)^2 * r_hat, where E_0 is a constant. Find t
Find the magnitude difference between two points located 1.4 m apart in a uniform 650 N/C electric field, if a line between the points is parallel to the field.-Potential difference V = integral of th
Consider an asteroid with a radius of 17km and a mass of 3.1*10^15 kg.Assume the asteroid is roughly spherical.
Suppose the asteroid spins about an axis through its center, likethe earth, with a rota
Quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as spooky action at a distance. A team of researchers led by Anton

A steel (Youngs modulus 2.0 x 1011 N/m2) wire is strung between two supports attached to a ceiling. Initially, there is no tension in the wire when it is horizontal. A 86-N picture is then hung from t
Air undergoes dielectric breakdown at a field strength of 3Mv/m.
Could you store energy in a uniform electric field in air with the same energy density as that of liquid gasoline?-The energy density s
1. Kevin and Justin have a body slam competition on Skates. Kevin (60kg) and Justin (65kg) skate into each other with the same velocity (8m/s). Justin continues forward with a velocity of 0.1m/s. They
Zoltan supports a 5m long 10kg beam at one end. The beam is uniform in cross section and in density, and is supported at the other end by a bench.
Q: What force must Zoltan exert in order to keep the
The moiré technique can be applied to problems of fields and flows. Thus in hydrodynamics the flow of liquid from a source may be represented by a figure of radiating lines; the greater the source str
