1.) The field just outside a 4.49cm -radius metal ball is 6.08×102N/C and points toward the ball. What charge resides on the ball?
2.) A flat circle of radius 20 cm is placed in a uniform electric field of magnitude 6.6×102N/C
a) What is the electric flux through the circle when its face is perpendicular to the field lines?
b) What is the electric flux through the circle when its face is at 30 to the field lines?
c) What is the electric flux through the circle when its face is parallel to the field lines?
Tim walks half of the time and runs the other half. In terms of given quantities, in the special case that, what will be Tim's margin of victory.
Assume the masses described in the preceding problem are 1kg and 100kg in that order. Compare the accelerations while they are interchanged.
The ends of two thin glass tubes are stuck in the same pool of water. Although both tubes are thin, one tube has a smaller inside diameter (Tube 1) than the other (Tube 2). Both tubes are made of the same material. Would you expect the level in Tu..
A cart of mass M = 1.6 kg can roll without friction on the level track. A light string draped over a light, frictionless pulley connects the cart to a hanger with mass m = 0.7 kg.
What is the phase di erence between wavefronts originating from the two slits, at a point on the screen located +Π/10m from the zero'th order?
Whole blood has a surface tension of 0.068 N/M & a density of 1050kgm-3.what weight can whole blood rise in a capillary blood vessel that has radius 2.0 x 10-6 if the contact is zero.
A cable is used to raise a 29kg urn from an underwater archeological site. There is a 21 N drag force from the water as the urn is raised at a constant speed.
Illustrate what factors are likely to drive an organization's outlays for new capital? Illustrate what ratios would you use to help generate forecasts of these outlays?
A disk with a mass of 37.5kg and a radius of 38.3cm is mounted on a frictionless horizontal axle. A string is wound many times around the disk and then attached to a 56.4kg block. Find the acceleration of the block, assuming that the string does n..
The mass of a string is 1.00 10-3 kg, and it is stretched so the tension in it is 120 N. A transverse wave traveling on this string has a frequency of 260 Hz and a wavelength of 0.60 m. What is the length of the string?
What is the minimum coefficient of friction between tires and road that would allow cars to take the turn without sliding off the road.
