First off, Newton's second law<span> of motion is the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
So therefore, it would be a force is being applied to the mass</span>
Answer:
Explanation:
Ions are substances the have lost or gained a certain amount of electrons. This makes them either positively or negatively charged.
They are charged particles.
- Every atom is made up of protons, neutrons and electrons.
- They are the three fundamental particles in any atom
- The protons and neutrons are located in the central part called the nucleus of an atom. It is a simple tiny space.
- Protons are positively charged particles. Neutrons do not carry any charges. Therefore, the nucleus is negatively charged.
- Electrons are negatively charged particles. They occupy the bulk volume of an atom.
Every atom is neutral and the number of protons and electrons are the same. The equal number of protons and electrons balances to attain neutrality of an atom.
Electrons are very easy to lose since they occupy the outermost shell.
- When an atom loses an electron, the number of protons is more than electrons. Therefore, it becomes positively charged. Hence, its is called an anion.
- An atom can also gain an electron, the electron number will be more than the protons. They then become negatively charged and are called cation.
Cations and ions are substances that are produced to attain a special type of bonding called electrovalent bonding.
Oppositely charged substances attracts one another.
Answer:
A study looking at how alcohol consumption impacts the brain. A study to discover the components making up human DNA. A study accessing whether stress levels
Explanation:
For example, a scientist that tries to figure out how the body makes cholesterol, or what causes a particular disease, is performing basic scienc
F = ma
We have mass = 0.2kg
and acceleration = 20 m/s^2
So..
F = (0.2)(20)
F = 4 N
Explanation:
measurement of a set, accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other.
Accuracy has two definitions:
More commonly, it is a description of systematic errors, a measure of statistical bias; low accuracy causes a difference between a result and a "true" value. ISO calls this trueness.
Alternatively, ISO defines[1] accuracy as describing a combination of both types of observational error above (random and systematic), so high accuracy requires both high precision and high trueness.
Precision is a description of random errors, a measure of statistical variability.
In simpler terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be accurate if their average is close to the true value of the quantity being measured, while the set can be said to be precise if the values are close to each other. In the first, more common definition of "accuracy" above, the two concepts are independent of each other, so a particular set of data can be said to be either accurate, or precise, or both, or neither.
