Q. A silver wire 2.6 mm in diameter transfers a charge of 420 oC in 80 min. Silver contains 5.8 times 10^{28} free electrons per cubic meter.
What is the current in the wire?
What is the wavelength of radio waves. An electron in a TV is accelerated toward the screen across a potential difference of 54.2kV. How much kinetic energy does the electron gain while accelerating.
A 50-kilogram woman balances on one heel of a pair of high heel shoes. If the heel is circular with radius of .5 cm, what pressure does she exert on the floor.
For no apparent reason, a poodle is running at a constant speed of 4.40 {rm m/s} in a circle with radius 3.0 {rm m}. Let vec v_1 be the velocity vector at time t_1, and let vec v_2 be the velocity vector at time t_2.
What is the speed of projectile immediately before it hits the ground if air friction does one and a half times as much work on projectile when it is going down as it did when it was going up.
A brass plate measures 30 cm by 40 cm. The coefficient of linear thermal expansion is 19.0 10-6/°C. If the temperature of the plate is increased by 10.0 K, next what is the increase in the area of the plate? a) 0.350 cm2 b) 0.404 cm2 c) 0.456 cm2 ..
Two bars of identical mass are at 29 °C. One is made from glass and the other from another substance. The specific heat capacity of glass is 840 J/ (kg • C°).
How much energy is necessary to place three charges, each of 3.0 micro Coulomb's, at the corners of an equilateral triangle of side 2 cm.
After the engine is ignited, what is the rocket's speed when the spring has stretched 19.00 cm past its natural length? What would be the rockets speed after travelling the distance if it weren't tied down to spring.
There are two major types of aberration (defective image formation) in lenses: spherical and chromatic. Spherical aberration comes from fact that a spherical lens has the property of focusing parallel rays to a single point only approximately.
What should the charge (sign and magnitude) of a particle of mass 1.42g be for it to remain stationary when placed in a downward-directed electric field of magnitude 670N.
