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.
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 splitting of an atomic nucleus to form two smaller nuclei of roughly equal mass?
Nuclear fission
How is the altitude of the North Celestial Pole above the northern horizon related to the observer's latitude?
They're always within about 1/3 degree of each other ... close enough that they're said to be roughly equal.
Why transition metal have same atomic radius?
this is because the effect of the increased nucleus i roughly balanced by the greater screening effect produced by adding to the penultimate shell
What is the shape of the nucles?
The nucleus is roughly spherical
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.
How many times smaller is the nucleus than the atom?
The atom has roughly 1E15 times the volume of its nucleus.
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.
Why the size of atom is biggest than nucleus?
Because there are electrons around the nucleus which form a cloud the nucleus is a part of this cloud roughly atom is 8000 times bigger than an average nucleus.
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.
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 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 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.
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.
Nuclear reaction in which an unstable atomic nucleus splits into two roughly equal parts?
Fission.
What is a group of electrons orbiting at roughly the same distance from the nucleus called?
electron cloud
