If you weigh 660 n on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 19.0 km ? take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be g = 6.67×10? 11 n? m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 . express your weight wstar in newtons.

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.
