In a Hall-effect experiment, a current of 4.0 A sent lengthwise through a conductor 0.8 cm wide, 3.6 cm long, and 9 ?m thick produces a transverse (across the width) Hall potential difference of 8.0 ?V when a magnetic field of 1.7T is passed perpendicularly through the thickness of the conductor. From these data,
A) find the drift velocity of the charge carriers.
B) Find the number density of charge carriers.
A charge of 6.53mC is placed at each corner of a square .470 m on a side. Determine the magnitude of the force on each charge. Determine the direction of the force on each charge.
A shot fired with a velocity 100 m/s on a direction making an angle 60 degree with vertical. Calculate the time of flight
A small, 100g cart is moving at 1.2 m/s on an air track while it collides with a larger, 1.00kg cart at rest. After the collision, the small cart recoils at .850 m/s. what is the speed of the large cart after the collision.
An ion accelerated through a potential difference of 102 V experiences an increase in kinetic energy of 3.01 × 10?17 J
A cylinder of gas at room temperature (20°C) has a pressure p1. To what temperature in degrees Celsius would the temperature have to be increased for pressure to be 2.7p1.
What is the electric field strength between the disks. What is the speed of the box at the end of the 5.7-s interval.
The alpha line in the Balmer series of the hydrogen spectrum consists of light having a wavelength of 6.56 ×10-7 meter. Compute the frequency of this light.
A 3.06 kg block slides down a frictionless plane inclined 18.6' to the horizontal. If length of the plane's surface is 1.43 m, how much work is done, and by what force.
The coefficient of static friction between the 3000 lb car's tires and the road is 0.5. Determine the steepest grade the car can drive up at constant speed if car has (a) rear=wheel drive; (b) front-wheel drive; (c) four wheel drive.
A 0.5970-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water, calculate the final temperature of the puddle once it settled to equilibrium
A single loop of wire with an area of 0.0900 m2 is in a uniform magnetic field that has an initial value of 3.80 T, is vertical to the plane of the loop, and is decreasing at a constant rate of 0.190 T/s.
A block of mass m = 2.00 kg is dropped from height h = 90 cm onto the spring of spring constant k = 1960 N/m. Find out the maximum distance the spring is compressed.
