A huge cannon is assembled on an airless planet having insignificant axial spin. The planet has a radius of 5.00 × 106 m and a mass of 3.95 × 1023 kg. The cannon fires a projectile straight up at 2000 m/s
An observation satellite orbits the planet at a height of 1000 km. What is the projectile's speed as it passes the satellite? (G = 6.67 × 10-11 N • m2/kg2) A) 1500 m/s B) 1380 m/s C) 1610 m/s D) 1280 m/s
Determine the increase in the open spacing between precipitate particles that occurs when the 2014 aluminum alloy shown in Figure 7.17 is aged for 1000 h at 149°C (300°F), relative to the value at peak strength that is calculated in Example Problem 7.5. Assume that the as-quenched yield strength of 100 MPa is the value of ?0, that the lattice parameter of FCC aluminum is 0.404 nm, and that the shear modulus of this alloy is equal to that of aluminum given in Table 6.1.

Astronomers speculate that most galaxies have a massive black hole at their center. What could be the origin of the suspected black hole?
A. The gravitational attraction drew in stars from the disk. B. the collision of galaxies C. the rapid rotation of the galaxy that compressed material to high densities D. dark matter at the galactic center E. First, a supernova explosion formed a black hole, which in time became more massive by accretion.
