Ga projectile is shot directly away from earth's surface. neglect the rotation of the earth. what multiple of earth's radius re gives the radial distance (from the earth's center) the projectile reaches if (a) its initial speed is 0.216 of the escape speed from earth and (b) its initial kinetic energy is 0.216 of the kinetic energy required to escape earth? (give your answers as unitless numbers.) (c) what is the least initial mechanical energy required at launch if the projectile is to escape earth?

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
