Find the roche limit for this system

Reference no: EM13536948

The Earth is about to be swallowed by a black hole with the mass equal to ten Solar masses. At what distance from the black hole will the Earth be pulled apart by tidal forces - i.e. find the Roche limit for this system.

[Hint: note that the formula involving densities will not be particularly useful in this situation, since you do not know the 'density' of a black hole.]

What is the instantaneous AC current : A circuit contains only a(n) 0.219 H inductor. An AC voltage of peak value 163 V and frequency 61.3 Hz is applied to the circuit. When the instantaneous voltage is 163 V, what is the instantaneous AC current?

Angle theta-inclined face of wedge makes with the horizontal : A 700 gram sphere A moving with a velocity v_0 parallel to the ground strikes the inclined face of a 2.1 kg wedge B which can roll freely on the ground and is initially at rest. After impact the sphere is observed from the ground to be moving stra..

Jupiter crossing the face of the sun : An observer is at 5pc from the Sun in the plane of Jupiter's orbit. Once in 11.9 years Jupiter crosses the disk of the Sun. He cannot resolve the Solar disk nor the Jupiter (cf. HW1), but he observes slight dimming of the star. What is the magnitu..

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..
