A 310-km-long high-voltage transmission line 2.0 cm in diameter carries a steady current of 1,150 A. If the conductor is copper with a free charge density of 8.5 1028 electrons per cubic meter, how many years does it take one electron to travel the full length of the cable? (Use 3.156 107 for the number of seconds in a year.)
n a cathode ray tube, electrons are accelerated from rest by a constant electric force of magnitude 6.6 ? 10-17 N during the first 1.9 cm of the tube's length, Find the speed of the electrons when they hit the screen
A sphere of mass 2.8 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes an angle of 40° with vertical when at rest.
A submarine dives 90.0 m at an angle of 8.0° below the horizontal. What are the horizontal and vertical components of submarine's displacement? (Imagine that upward and the direction of the submarine's horizontal motion is positive.)
Two equally charged particles, held 22.4 cm apart, are released from rest. The initial acceleration of the first particle is observed to be 4.0 m/s2 and that of the second particle is 6.0 m/s2.
A bullet is fired horizontally from a 100 m, t all building with a speed of 900 m? How long will it take to hit the ground?
A curve of radius 152 m is banked at an angle of 11°. An 722-kg car negotiates the curve at 86 km/h without skidding. avoid the effects of air drag and rolling friction.
What should be the spring constant of a spring designed to bring a 1400 car to rest from a speed of 95 so that the occupants undergo a maximum acceleration of 5.
What is the speed of the arrow as it leaves the bow.Two point charges, Q_1 = -6.9 mu C and Q_2 = 2.0 mu C are located between 2 oppositely charged parallel plates.
A toy car with mass of m=166 GRAMS crashes into a spring with constant k=45 N/m. If the car was going v=1.5 m/s, then how far will the spring compress.
In an X-ray tube electrons strike a tungsten target (W or "wolfram") after being accelerated through a potential difference V0. Estimate the minimum value of V0 required to observe the Kalpha peak.
On a cool morning, when the temperature is 14 degrees C, you measure the pressure in your car tires to be 30 psi. After driving 50 mi on the freeway, temperature of your tires is 52 degrees C.
A child and sled with a combined mass of 55.20 kg slide down a frictionless hill that is 7.84 m high at an angle of 26o from horizontal. The acceleration of gravity is 9.80 m/s2. If the sled starts from rest, what is its speed at the bottom of hil..
