strength of the magnetic field strongest point a or point b?
The position is the strength of the magnetic field strongest is is the place where the magnetic field leaves, being point A.
What generates a magnetic field?When an electrically charged particle moves, it creates a magnetic field. According to the laws of electromagnetism, this magnetic field originates from the variation of the electric field strength.
In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense.

The electrons that are in the outermost electron shell, also known as the ____________ , have ____________ energy than those in the inner electron shells.
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The outermost electrons are called valence electrons and its energy is higher than the core electrons.
What is atom?Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

a: interpreting data and drawing conclusions
b: stating the problem and making a hypothesis
c: devising an investigation and looking for cause and effect relationships
d: deciding what the outcome should be and recording it
the most important methods are A and B
When using a scientific method, two of the most important steps are stating the problem and making a hypothesis. So the correct option is B.
What is a scientific hypothesis?Any kind of biological investigation will generally start with an observation. An observation is something that catches the attention of the biologist. For example, a microbiologist notices that a bacteria is not stained by any stain and wonder why this is happening.
The base of biology and other sciences have a problem-solving approach called the scientific method. The scientific method has five main steps and an additional feedback step:
Making an observation.Asking a question.Forming a hypothesis or testable explanation.Making a prediction based on the hypothesis.Testing the prediction.Iterating the use of the results to make new hypotheses or predictions.Therefore, when using a scientific method, two of the most important steps are stating the problem and making a hypothesis.

The heat absorbed by 47.5g of silver (Ag) when the temperature rises by 10 °C is 111.625 J .
What is Specific Heat ?Specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree.
The units of specific heat are usually calories or joules per gram per Celsius degree.
The equation used to solve for specific heat capacity is this:
q = mcΔT
where q heat absorbed or lost,
c is the specific heat capacity,
m is the mass, and
ΔT is the change in temperature
= final temperature− initial temperature
Given that m = 47.5g
ΔT = 10 K
Specific Heat of silver = 0.235 J/gK
Therefore
q = 47.5 * 0.235 * 10
q= 111.625 J

The number of moles of C present in C₅H₁₂ that contains 22.5 g of H is 9.375 moles
How to determine the mass of C₅H₁₂ that contains 22.5 g of H
1 mole of C₅H₁₂ = (12×5) + (1×12) = 72 g
Mass of H in 1 mole of C₅H₁₂ = 12 × 1 = 12 g
Thus,
12 g of H is present in 72 g of C₅H₁₂
Therefore,
22.5 g of H will be present in = (22.5 × 72) / 12 = 135 g of C₅H₁₂
How to determine the mole of C present in 135 g of C₅H₁₂72 g of C₅H₁₂ contains 5 moles of C
