Surface equals the free-fall acceleration on earth

Reference no: EM13536942

It has been suggested that rotating cylinders about 8.0 mi long and 5.0 mi in diameter be placed in space and used as colonies. What angular speed must such a cylinder have so that the centripetal acceleration at its surface equals the free-fall acceleration on Earth?

Phase angle between the current and the applied voltage : An RLC circuit consists of a 863 ? resistor, a 49 µF capacitor, and a 265 mH inductor, connected in series with a 78.2 V, 96 Hz power supply. What is the phase angle between the current and the applied voltage? Answer between -180? and +180?

What is the speed of the signal as measured in S : A rocket is traveling at speed V along the x axis of frame S. It emits a signal (for example, a pulse of light) that travels with speed c along the y' axis of the rocket's rest frame S'. What is the speed of the signal as measured in S?

Transformation is in fact standard lorentz transformation : Frame S' travels at speed V_1 along the x axis of frame S (in the standard configuration). Frame S'' travels at speed V_2 along the x'' axis of frame S'; (also in the standard configuration). By applying the standard Lorentz transformation twice find..

Phenomenon is called the relativity of simultaneity : A traveler in a rocket of proper length 2d sets up a coordinate system S' with its origin O' anchored at the exact middle of the rocket and the x' axis along the rocket's length. At time t' = 0 she ignites a flashbulb at O'.

Two converging lenses : Two converging lenses, one with f = 4.5cm and the other with f = 44 cm, are made into a telescope. Assume these lenses are now combined to make a microscope; if the magnification needs to be 25 X, how long would the microscope be?

How far away can a human eye distinguish : How far away can a human eye distinguish two car headlights 1.8 m apart? Consider only diffraction effects and assume an eye pupil diameter of 5.5 mm and a wavelength of 550 nm. What is the minimum angular separation an eye could resolve when view..

What is the heat gain per unit length of the duct : Airflow through a long, 0.2 m^2 air conditioning duct maintains the outer duct surface temperature at 10 C. If the horizontal duct is uninsulated and exposed to air at 35 C in the crawl space beneath a home, what is the heat gain per unit length of t..
