Answer:
Explanation:
i. Accuracy in measurement is a term that is used to describe the closeness of a measured value to its actual value. It relates the actual value to the measured values.
Therefore in the given question, Amy's measurement of the salt's mass is accurate because her final value is close to all the measured values.
ii. Precision in measurement is a term that is used to describe the closeness of different measured values to each other. It relates the keenness in the measured values.
Thus, Amy's measurements of the salt's mass is precise because the values of the masses are close to one another.
Answer:
θ₁ = 3.35 10⁻⁴ rad
, θ₂ = 8.39 10⁻⁵ rad
Explanation:
This is a diffraction problem for a slit that is described by the expression
sin θ = m λ
the resolution is obtained from the angle between the central maximum and the first minimum corresponding to m = 1
sin θ = λ / a
as in these experiments the angle is very small we can approximate the sine to its angle
θ = λ / a
In this case, the circular openings are explicit, so the system must be solved in polar coordinates, which introduces a numerical constant.
θ = 1.22 λ / D
where D is the diameter of the opening
let's apply this expression to our case
indicates that the wavelength is λ = 550 nm = 550 10⁻⁹ m
the case of a lot of light D = 2 mm = 2 10⁻³ m
θ₁ = 1.22 550 10-9 / 2 10⁻³
θ₁ = 3.35 10⁻⁴ rad
For the low light case D = 8 mm = 8 10⁻³
θ₂ = 1.22 550 10-9 / 8 10⁻³
θ₂ = 8.39 10⁻⁵ rad

Metaphysics is the systematic inquiry into the nature of reality. This is a True statement.
<h3>What is metaphysics?</h3>
Metaphysics is defined as the branch of philosophy that deals with the nature of reality and how life started on earth.
The concept of metaphysics believes that what cannot be reached through objective studies of material reality can be studied.
There are three major categories of metaphysic that is being studied which include the following:
- Ontology or general metaphysics,
- Psychical or religious metaphysics, and
In conclusion, metaphysics is the systematic inquiry into the nature of reality because it questions reality outside of human sense of perception.
