The answer is D. What makes a neutral atom neutral is that it has an even number of protons and neutrons. If the number of protons and neutrons are unbalanced, it is now an ion.

Answer:

D

Explanation:

An ion is created because an atom doesn't have a balanced number of protons and electrons. A positive ion is created by an atom losing an electron and a negative ion is created by an atom gaining an electron.

Suppose an egyptian mummy is discovered in which the amount of​ carbon-14 present is only about oneone​-fifthfifth the amount fo
poizon [28]

We are given the following equation:

y = y0 e^-0.0001216 t

where y = 1/5 y0, y0 is the original amount

So solving for time t:

1/5 y0= y0 e^-0.0001216 t

t = 13,235.51 years

The nutritional energy content (in Calories) present in 86g of broccoli with 6g of carbohydrates, 2.6g of protein, and 0.3g of f
asambeis [7]

Answer:

37.1 calories.

Approximately, 37.1 = 40 calories.

Explanation:

So, without mincing words let's dive straight into the solution to the question above.

We are given the following parameters which are going to help in solving this particular Question.

The mass of broccoli = 86g of broccoli, mass of carbohydrates present = 6g of carbohydrates, the mass of protein present = 2.6g of protein and the mass of fat present = 0.3g of fat.

Therefore, the nutritional energy content (in Calories) = (6 × 4) + (2.6 × 4) + (0.3 × 9) = 10.4 + 24 + 2.7 = 37.1

Hence, the nutritional energy content (in Calories) = 37.1 calories.

Approximately, 37.1 = 40 calories.

Is Newton's statement a law or a theory? It is a theory because it developed and changed over time as new technology provided ne
nika2105 [10]

Answer:

It is a law because it is a statement of fact that does not need any more experimental support.

Explanation:

A hypothesis is an acceptable assumption that is formulated through the collection of information and data and that attempts to explain some phenomenon. In other words, a hypothesis is a conjecture with which one tries to explain an observed fact. The formulation of a hypothesis can be derived in two different ways: by generalization, from a certain number of cases or observed phenomena; and, by analogies observed in the occurrence of different phenomena.

A theory is something that attempts to explain some phenomenon and that is accepted as true by the scientific community. In other words, a theory is a set of rules that describe the behavior of a particular system.

A law is a statement that expresses the constant relationships between phenomena of nature, society or the mind. Scientific law can be defined as an invariable relationship of terms. In other words, a law is what is scientifically proven to be true, it is universally applicable.

So scientific theories and scientific laws are based on hypotheses. But a theory is the explanation of an observed phenomenon, while a scientific law is the description of an observed phenomenon.

The movements of bodies in space are governed by Newton's Laws. These are laws why they are demonstrated by mathematical formulas and Universal application.

Then, the correct option is <u><em>"It is a law because it is a statement of fact that does not need any more experimental support."</em></u>
