Q. A 550 turn solenoid, 25 cm long, has a diameter of 2.5 cm. A 10 turn coil is wound tightly around the center of the solenoid. If the current in the solenoid increases uniformly from 0 to .60 s, what will the induced emf in the short coil during this time.
Q. A cylindrical container with a cross-sectional area of 66.2 holds a fluid of density 816kg/m3, and the bottom of the container the pressure is 118 kPa. What is the depth of the fluid?
If the average frequency emitted by a 200,-, rm W light bulb is 5.00 times 10^ {14}, {rm Hz}, and 10.0 percent of the input power is emitted as visible light, about how many visible-light photons are emitted per second.
A wheel of diameter 5.8 cm has a 4 m cord wrapped around its periphery. Starting from rest, wheel is given a constant angular acceleration of 4.9 rad/s2. How much time it will take for the cord to unwind.
Determine magnitude of the force
A 79, 37--long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 13 ball of clay travelling horizontally at 2.6 hits and sticks to the extremely bottom tip of the rod.
A Carnot engine performs work at the rate of 480 kW as using 640 kcal of heat per second. If the temperature of the heat source is 540°C, at what temperature is the waste heat exhausted.
A simple harmonic oscillator consists of a block of mass 4.kg attached to a spring of spring constant 153 N/m. When t = 2 s, the position and velocity of the block are x = +0.129 m and v = +3.415 m/s.
A bullet of mass 0.0022 kg initially moving at 496 m/s embeds itself in a large fixed piece of wood and travels 0.64 m before coming to rest. Imagine that an acceleration of the bullet is constant.
What is the difference between mass and weight? On earth, what is the weight of a 1 kg mass?
What is magnitude of the greatest force
Determine the coefficient of kinetic friction between the block & the table.
A helicopter is ascending vertically with a speed of 5.45m/s. At a height of 141m above the Earth, a package is dropped from a window. How much time does it take for package to reach the ground.
A test rocket is fired vertically upward from a well. A catapult gives it an initial speed of 80.6m/s at ground level. Its engines then fire and it accelerates upward at 3.80 m/s2 until it reaches an altitude of 930m. At that point its engines fai..
