3) How much current will be flowing through a 40m length of copper wire with radius 4 mm if it is connected to a source supplying 16 V? (The resistivity of copper is 1.68*10^-8*mA) 68 nA B) 1200 A C) 9.5 x 108 A D) 710 A
5) A 3.0 V battery that can store 400J of energy is connected to a resistor. How much electrical charge must flow between the battery's terminals to completely drain the battery if it is fully charged?A) 0.02 C B) 1200 C C) 130 C D) 0.01 C
6 A 5.0V potential difference is applied between the ends of a 0.80mm -diameter, 90cm -long nichrome wire.6 cont.
Part A What is the current in the wire?Express your answer using two significant figures.I = A
The gravitational force exerted on a baseball is 2.23 N down. A pitcher throws the ball horizontally with velocity 14.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 169 ms. The ball starts from rest.
A long horizontal wire carries a current of 48 {rm A}. A second wire, made of 2.6 mm diameter copper wire and parallel to the first, is kept in suspension magnetically 15 {rm cm} below. Examine the magnitude of the current in the lower wire.
A lighthouse that rises 49 above the surface of water sits on a rocky cliff that extends 19 from its base. A sailor on the deck of a ship sights the top of the lighthouse at the angle of 30.0 above the horizontal.
Assume that the masses of the chains, pulleys, and ropes are negligible and the crate is rising with an acceleration of 2.6 m/s2. Identify the force.
A particle moves along the x-axis according to the equation x(t) = 2.0 + 3.0t2 - 1.0t3, where x is in meters and t is in seconds. What is the position of this particle when it achieves its maximum speed in the positive x-direction? What is its spe..
Two people with a combined mass of 120kg hop into an old car with worn-out shock absorbers. This causes the springs to compress by 8.30 cm. When the car hits a bump in the road, it oscillates up and down with a period of 1.70s.
Light of wavelength 588 nm falls on a double slit. First-order bright bands appear 3.65 cm from the central bright band. The screen is 1.20 m from the slits. How far apart are the slits.
Two charged objects experience a mutual repulsive force of N. If the charge of one of the objects is reduced by a factor of and the distance separating the objects is increased by a factor of , what is the new force?
What is the magnitude of the vertical component of its velocity as it strikes the ground.
A playground merry-go-round has radius 3-{rm m} and moment of inertia 3000-{rm{ kg}} cdot {rm{m}}^2 about a vertical axle through its center, and it turns with negligible friction.
A positively charged rod is brought close to one end of an uncharged metal rod but does not actually touch it. What type of charge does the end of the metal rod closest to the positively charged rod acquire?
Two projectiles are thrown with the same initial speed, one at an angle with respect to the level ground and the other at angle 90 degree. Both projectiles strike the ground at the equivalent distance from the projection point. Are both projectiles i..
