Question: A sinusoidal input u = 10 sin(100t) is provided to an unknown first-order system, which serially connects to a first-order transducer system defined by a sensitivity of 1.2 and a time constant of 0.01 s. The output from the transducer is further fed into a filter-amplifier device, which acts as a second-order system with a sensitivity of 3, a natural frequency of 300 rad/s, and a damping ratio of 0.3. Knowing that the signal output from the filter-amplifier system has an amplitude of 200 and a phase angle of -70° with respect to the sinusoidal input, evaluate the unknown first order system parameters.
What effect does the magnetic field have on the speed of the particle? What are the magnitude of the acceleration of the alpha particle while it is in the magnetic field?
A pendulum, consisting of a ball of mass m on a light string of length 1.00 m, is swung back to a 45° angle and released from rest. What is the block's speed after the collision
an apple drops from the tree and falls freely. the apple is originally at rest a height h0 above the top of the grass
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..
A permanent bar magnet has a field strength of 1T. Assume we have a circular wire loop of radius R=0.50 cm that is carrying a current of I Amperes. What current is necessary to make a magnetic field at the center of the wire loop that is equal to the..
a car travels up a hill at a constant speed of 55 kmh and returns down the hill at a constant speed of 22 kmh.
We can roughly model a gymnastic tumbler as a uniform solid cylinder of mass 70.0kg and diameter 1.00m . A) If this tumbler rolls forward at 0.550 rev/s, how much total kinetic energy does he have? B) What percent of his total kinetic energy is ro..
A tank of water sits at the edge of a table of height 0.9 meter. The tank springs a very small leak at its bottom, and water sprays out a distance of 2.2 meter from the edge of the table. Determine the water level h in the tank
State the argument by which the ideal gas law is determined. Derive the ideal gas law from Boyle's Law and Gay-Lussac's Law.
A hair dryer is rated at 1700 W when connected to a 120 V source. Find the resistance of the hair dryer as well as the current in the hair dryer when it is turned on
To focus a camera on objects at dissimilar distances, the converging lens is moved toward or away from the image sensor, so a sharp image always falls on the sensor. A camera with a telephoto lens (f= 200.0mm) is to be focused on an object located fi..
