Part A Isaac Newton's universal law of gravitation is an expansion of the planetary motion ideas developed by
Johannes Kepler. One derivative of Newton's universal law gives us a useful formula to find tidal forces on
Earth caused by either the Sun or Moon. The tidal force depends on the mass m of the Sun or Moon, the
radius r of Earth, and the cube of the distance d between Earth and either the Sun or Moon. (The G in the
equation is known as the gravitational constant, and it doesn't change.)
Fsdal =
Based on the equation and your knowledge of the Sun-Earth-Moon system e, which celestial body (the
Sun or the Moon) has a greater influence on Earth's tides? Justify your answer.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
