The approximate value ofgat an altitude above Earth equal to one Earth diameter is:
" A. 9.8m/s2 B. 4.9m/s2 C. 2.5m/s2 D. 1.9m/s2 E. 1.1m/s2"
"Venus has a mass of about 0.0558 times the mass of Earth and a diameter of about 0.381 times the diameter of Earth. The acceleration of a body falling near the surface of Venus is about:"
" A. 0.21m/s2 B. 1.4m/s2 C. 2.8m/s2 D. 3.8m/s2 E. 25m/s2"
"Let M denote the mass of Earth and let R denote its radius. The ratiog/Gat Earth’s surface is:"
" A. R2/M B. M/R2 C. MR2 D. M/R E. R/M"
"Let F1 be the magnitude of the gravitational force exerted on the Sun by Earth andF2be the magnitude of the force exerted on Earth by the Sun. Then:"
" A. F1is much greater than F2 B. F1is slightly greater than F2 C. F1is equal to F2 D. F1is slightly less than F2 E. F1is much less than F2"
A hydrogen bond is really a weak kind of force that forms a special sort of dipole-dipole attraction which occurs when a hydrogen atom bonded to you...
An atomic orbital is a map that describes the wave-like behavior of both electron or maybe a pair of electrons within the atom.
The valence electrons are strongly attracted to the nucleus for elements with large ionization energies. One would expect these species to readily ac...
