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.)

Based on the equation and your knowledge of the Sun-Earth-Moon systeme, which celestial body (the Sun or the Moon)
has a greater influence on Earth's tides? Justify your answer.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
