Does the circumference of a circle vary directly with its radius?
yes
What is the radius of a star?
The radius of a star is a measure of its size, typically expressed in units such as solar radii, where one solar radius is the radius of the Sun, approximately 696,340 kilometers (about 432,690 miles). The radius can vary widely among different types of stars, ranging from less than a third of the Sun's radius for small red dwarfs to more than 1,000 times the Sun's radius for massive supergiants. The radius is determined through methods such as observing the star's brightness, temperature, and spectral characteristics.
The grade 6 pupils of a school are divided equally into Team A and Team B. The ratio of the number of boys to the number of girls in Team A is 21 and in team B is 411. What is the ratio of the number?
To find the overall ratio of boys to girls in both teams, we first need to determine the number of boys and girls in each team based on their ratios. For Team A (ratio of boys to girls is 2:1), let’s assume there are 21 boys and 10 girls, giving a total of 31 students. For Team B (ratio of boys to girls is 4:1), let’s assume there are 4 boys and 1 girl, giving a total of 5 students. However, the actual numbers may vary, but the overall ratio of boys to girls will depend on the actual numbers divided into the teams. Since you mentioned the ratios but not the total students, we can assert that the ratios within each team will affect the overall ratio when combined.
What is a proportional ratio?
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
What is the core radius?
The core radius refers to the radius of the central region of a structure, such as a star, planet, or fiber. In astrophysics, it often denotes the size of the dense, central part of a star where nuclear fusion occurs. In materials science, it can describe the radius of the core of a fiber optic cable or composite material. The specific definition can vary depending on the context in which it is used.
What is the oxidation number and coordination number of rhodium in the coordination compound?
The oxidation number of rhodium in a coordination compound can vary, but it is commonly found in the +2 or +3 oxidation state. The coordination number of rhodium in a coordination compound is typically 6, as it can coordinate with up to six ligands.
What is the coordination number of phosphorus?
The coordination number of phosphorus can vary depending on its oxidation state and the molecules or ions that it is bonded to. In most common cases, phosphorus can have a coordination number of 3 or 5 in various chemical compounds.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
Does the circumference of a circle vary directly with its radius?
yes
What is the male to female ratio for black people?
The male to female ratio for black people can be find out :By finding the number of males who are black.By finding number of females that are black.By diving the number of male by female.
What is the student teacher ratio for kindergartner's in Florida?
The maximum student to teacher ratio in Florida is regulated by the senate. The maximum allowed number of students per teacher for grades preschool through 3rd grade is 18. The actual ratio will vary from school to school.
How does the nuclear radius vary with atomic mass number?
The nuclear radius R is related to the mass number A as follows:R=RoA1/3,where Ro =constant=(1.2 to 1.7) x 10 -15Thus nuclear radius varies as A1/3
How does the atomic radius vary in a period?
Atomic radius decreases across a period from left to right, except for the noble gases.
What is the atom ratio of C to H?
The atom ratio of C to H in a molecule can vary depending on the specific compound. However, a common ratio in organic compounds is 1:1, meaning there is an equal number of carbon and hydrogen atoms in the molecule.
How does the size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
What is the ionic radius of copper?
The ionic radius of copper can vary depending on its oxidation state. For example, the ionic radius of Cu2+ is approximately 73 pm, while the ionic radius of Cu+ is around 77 pm.
How much is the sand for a mix ratio cement in weight?
It depends on what you are mixing for. The ratio would vary for specific applications.
