A very long, straight solenoid with a cross-sectional area of 5.75cm^2 is wound with 36 turns of wire per centimeter, and the windings carry a current of 0.275A . A secondary winding of 2 turns encircles the solenoid at its center. When the primary circuit is opened, the magnetic field of the solenoid becomes zero in 5.05*10^-2s.
What is the average induced emf in the secondary coil?
An object with mass 4.0kg is executing simple harmonic motion, attached to a spring with spring constant 300N/m, Calculate the max speed obtained by the object
A concave mirror has a radius of curvature of 24cm. Determine the object position for which the resulting image is upright, draw a ray diagram to determine the position of the image
At this time it has reached a height of 420 metres above launch pad and attained an upward velocity of 50 ms-1. From this time on, the rocket has constant upward acceleration -10 ms-2 (due to the effect of gravity alone).
A disk of radius 1.00 m is rotating with 5.39 rad/s and 5.39 rad/s2. What is the magnitude of the linear acceleration of a point on the outer edge of disk? (Give the answer in three significant figures and SI units)
Use the ideal gas approach to find the thermal velocity, and determine the scaling law based on the resulting equation
assume the roller coaster (h1 = 34 m, h2 = 10 m, h3 = 20) passes point A with a speed of 2.00 m/s. If the average force of friction is equal to one sixth of its weight, with what speed will it reach point B? The distance traveled is 45m.
During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 120 N to the tire's rim. what force must be applied to the chain
You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
A flower pot on a balcony railing falls to the ground 8.63m below. A cat directly beneath the pot sees it begin to fall. How long does cat have to move.
Determine the magnitude of door's angular acceleration.
A uniform plank of length 5.8m and weight 229N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 450N walk on the overhanging part of the plank be..
A 3.0-kg block sits on top of a 5.0-kg block which is on a horizontal surface. If the force is 10% greater than your answer for (a), what is the acceleration of each block
