Two identical probes are sent along the same path toward a neutron star. A neutron star is very dense, packing as much as 2 solar masses2 solar masses into a sphere with a radius on the order of 10 km. At the moment shown, the two probes are d=55.3 kmd=55.3 km and D=178 kmD=178 km away from the center of the neutron star, respectively.

Find the distance between the center of mass of the two probe system and its center of gravity.

Expert Solution

__________________________________________

For center of mass

=> X cm = ( M*55.3 + M*178 ) /2M

= 116.65 km

For center of gravity

Gravitational Force , F1 = GMm/55.3²

Gravitational Force , F2 = GMm/178²

=> Center of gravity = ( GMm/55.3² * 55.3 + GMm/178² * 178) / ( GMm/55.3² + GMm/178² )

= 66.1004 km

=> distance b/w center of mass and center of gravity = 116.65 km - 66.1004 km

= 50.55 km

Take two identical closed strings, both tracing out exactly the same path in space. These two strings are coincident everywhere. Call this state I. Take a single closed string following exactly the same closed path as in the first case, but not closing just yet. The string goes around exactly the same path once again before closing in on itself. Two cycles around the same closed path. Call this state II. String field theory tells us unambiguously states I and...

A space vehicle is advancing toward a planet along a parabolic path under the influence of the gravitational force from the planet. The space vehicle will come within 227 kilometers above the planet's surface, when the captain will engage the engines to slow the space vehicle and place it in a circular orbit 227 km above the surface. (Note: The energy of the space vehicle-planet system for a parabolic orbit is E = 0.) (a) By what percentage must the...

Two sinusoidal waves, identical except for phase, travel in the same direction along a string, producing the net wave: y(x,t) = (63.2 cm) * sin(1.4*x - 2.1 s-1*t + 0.24 rad); with x in meters and t in seconds. What is the phase difference between them? Give answer in radians. Do not enter unit. What is their amplitude? What is the wavelength of the two waves? What is their period?

What phase difference between two otherwise identical traveling waves, moving in the same direction along a stretched string, will result in the combined wave having an amplitude 1.3 times that of the common amplitude of the two combining waves? Express your answer in (a) degrees, (b) radians, and (c) as a fraction of the wavelength.

Two identical firms compete in a Bertrand duopoly. The firms produce identical products at the same constant marginal cost of MC = $10. There are 2000 identical consumers, each with the same reservation price of $30 for a single unit of the product (and $0 for any additional units). Under all of the standard assumptions made for the Bertrand model, the equilibrium prices would be Group of answer choices $10 for both firms $30 for both firms $50 for both...

Two firms have the same technology and pay the same wages for labor. They have identical factories, but firm 1 paid a higher price for its factory than firm 2 did. They both maximize their profits and have upward-sloping marginal cost curves. Explain whether our theory would predict firm 1 to have a higher output than firm 2.

Consider two economies that are identical in all dimesions -- the same population, same saving rate, the same production function, etc, -- except for the fact that one has a level of productivity that is twice as high as the other, that is Ah = 2Al . Assume both economies are in their steady states. what is the relationship between the levels of income per worker in these two economies?

There are two identical firms (A and B with the same total market value of equity (MVEt-1 = $20,000), total earnings (Et-1 = $1,000), same discount rate, same earnings persistence, etc. There is only one difference. Firm A has twice the number of shares outstanding (2,000 vs. 1,000) because A declared one 2:1 stock split in the past and B has never split its shares. Thus, B’s earnings per share (EPS) and stock price (P) is twice that of A’s....
