0.11 nm
1.1 nm
Answers
Answer:
0.11 nm
Explanation:
1.1 x 10-10 m
The goal is to convert the atomic radius from meters (m) to nanometres (nm). We do this by multiplying the value by 10^9.
This is given as;
[tex]1.1 * 10^{-10} * 10^{9}\\1.1 * 10^{-10 + 9}\\1.1 * 10^{-1}\\0.11[/tex]

A pebble is dropped into a cup of water and sinks to the bottom ofthe cup. A solid metal bead of exactly the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare?
Answers
Answer:
A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare? They both have the same mass. They are both denser than water.
Explanation:
nun
Answer:
Both the pebble and metal bead of the same mass will be equally accelerated if they are at the same place, in this case, they are in the same place meaning they will be accelerated at the same speed towards the earth. Thus even if they are in the water they will sink at the same speed and finally will reach the bottom of the cup.

What does these mean (thermal energy, convection, radiation and coundution)
Answers
Answer:
Thermal Energy: It refers to some distinct physical concepts, such as the internal energy of a system or heat or sensible heat. And these mode of transfer of heat include, convection, conduction and radiation which I have explained below.
Convection: This is a mode of transfer of heat in which bulk movement of molecules within fluids takes place, as these molecules move the heat obtained by each of the molecules will reach the new location.
Radiation: Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium
Conduction: Conduction is the transfer of internal energy by microscopic collisions of particles and the movement of electrons within an object.
The diagram shows a pedigree for a recessive inherited trait. If H represents the dominant allele and h represents the recessive allele what are the genptypes of the parents shown in the pedigree.
Answers
Answer:
Hh
Explanation:
if you have a dominant allele and a recessive allele they'd be different (heterozygous)
If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.
What is genotypes?The type of variation present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.
The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype. In a single experiment, the genotypes spanning millions of sites in a genome can be determined using DNA sequencing as well as other techniques. If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.
Therefore, Hh is the genotypes of the parents shown in the pedigree.

Explanation:
An empirical formula means that the chemical formula of a compound has to be in it's simplest whole number form. In this case, D is not an empirical formula because it is able to be simplified to C3H6. All the other answers are simplified to the simplest whole number ratio. Think of it as a fraction being in simplest form.
