How many moon diameters is it from the horizon to the zenith?
Apparent (visual) diameter of the [full] moon . . . . always near 1/2 degree. Angle from horizon to zenith . . . 90 degrees . . . roughly 180 apparent moon diameters.
Roughly what line of longitude was the westernmost boundary of the the United states in 1790?
In 1790, the westernmost boundary of the United States was roughly along the line of longitude 95° W. This boundary included territories that were part of the original thirteen colonies and some areas acquired through treaties, but it did not extend beyond this longitude until later expansions, such as the Louisiana Purchase in 1803.
What is true of an atom's nucteus?
A nucleus of an atom is at its center, it consists of protons and neutrons. The nucleus is roughly 10,000 times smaller than the whole atom.
What is the splitting of an atomic nucleus to form two smaller nuclei of roughly equal mass?
Nuclear fission is the process by which an atomic nucleus splits into two smaller nuclei of roughly equal mass. This process releases a large amount of energy, making it a key component in nuclear power plants and nuclear weapons.
What is the number density of gold?
The number density of gold (Au) can be calculated using its molar mass and density. Gold has a molar mass of approximately 197 g/mol and a density of about 19.32 g/cm³. This results in a number density of roughly 5.0 × 10²² atoms/cm³. Thus, gold is highly dense and contains a significant number of atoms in a given volume.
What is the shape of the nucles?
The nucleus is roughly spherical
Does the moon stay below the horizon at the poles for months like the sun does?
No. Seen from either pole, the moon is continuously below the horizon for roughly 14.8 days, followed by another 14.8 continuous days when it's above the horizon.
What does speciffic gravity mean?
Specific gravity is defined as the density of a substance, compared to the density of water. This is roughly equivalent to the density, expressed in kilograms/liter.
What is a group of electrons orbiting at roughly the same distance from the nucleus called?
A group of electrons orbiting at roughly the same distance from the nucleus is called an electron shell or energy level. These shells represent different energy levels in which electrons can orbit around the nucleus of an atom.
How many moon diameters is it from the horizon to the zenith?
Apparent (visual) diameter of the [full] moon . . . . always near 1/2 degree. Angle from horizon to zenith . . . 90 degrees . . . roughly 180 apparent moon diameters.
What is the relationship between the position of the north star and latitude?
The angle between the north star and the horizon is roughly your position in degrees latitude.For example, look at the North Star and point one arm straight at it, and then hold your other arm level with the horizon. The angle between your arms is roughly the degrees of latitude of your location.

Does candal wax float and what is its density?
Paraffin wax has a density of roughly 0.8 gm/cm3 . It will float in any fluid whose density is greater than roughly 0.8 gm/cm3.
Nuclear reaction in which an unstable atomic nucleus splits into two roughly equal parts?
Fission.
In the northern hemisphere the altitude height in degrees above the horizon of the North Star is Always roughly equal to the?
latitude of the observer
What feature runs roughly north soutb near th middle of the Atlantic ocean And south Atlantic?
subduction boundary
