Two planets have the same surface gravity, but planet B has twice the mass of planet A. If planet A has radius r, what is the radius of planet B? A) B)r C) We were unable to transcribe this image
If you have equal masses of two different substances (A and B), and the density of A is twice the density of B, then the volume of A is ________ the volume of B. a. The same as b. One-half c. Two times d. One-quarter e. Four times
Two countries, Alpha and Beta, have identical production possibilities frontiers. Capital goods (per person) If Alpha produces at point A and Beta produces at point B, then _ O A. Alpha's and Beta's economic growth rates will be the same O B. Beta's future consumption will be less than than Alpha's O C. Alpha consumes more than Beta today, but it will grow slower than Beta OD. Alpha's economic growth rate will exceed Beta's PPF Consumption goods (per person)
A spherical asteroid with radius of 18.6 km has uniform density 3500 kg/m3. Find the gravitational acceleration at the asteroids surface Express answer in two significant figures
Satellite A has twice the mass of satellite B, and circles in the same orbit. Compare the two satellite's speeds. The speed of B is twice the speed of A. The speed of Bis half the speed of A. A. The speed of Bis one-fourth the speed of A. The speed of B is equal to the speed of A. The speed of Halley's Comet, while traveling in its elliptical orbit around the Sun, O is constant increases as it...
Show the steps. Thank you
9. An isolated spherical spherical capacitor has charge +Q on its inner conductor (radius ra) and charge-Q on is outer conductor (radius rb). Half of the volume between the conductors is then filled with a liquid dielectric of constant K. Given [ra, Tb, Q, K] Determine: a. the capacitance of the half filled capacitor. b. The Electric Field in the volume between the two conductors as a function of distance r from the center of...
Hydrostatic Balance equation applied to planet interior structure: For lower mass rocky planets up to a few times the mass of the Earth, one can assume that the density p of the material making the planet is constant at any radius through the planet's interior. We want to evaluate the pressure at each radius r in the interior of such a planet. Using the hydrostatic balance equation we derived in class, we can slightly rewrite this relation for any interior...
A town has just one movie theater (Alpha) operating as a monopolist. Another firm (Beta) is considering entering the town's market. Suppose that the inverse demand curve each period for tickets in this town is given by P 200-Q, and the current firm faces the following total cost each period of TCi 30qi or a marginal cost and average cost of 30. The entrant has a total cost each period of TCe 40qetf or a marginal cost of 40 and...
Considering two firms, Alpha and Beta, the sales, profits, and assets of Alpha are $20 million $4 million and $40 million respectively, whereas Beta's sales, profits, and assets are $8 million $2 million, and $20 million, respectively, (1) What's the return on assets for each firm? 12) Applying the Du Pont system here to analyze the return on assets, what information you could further obtain by utilizing this method? (3) Please give me a famous brand of firm regarding each...
