Answer:
Density of 127 I =
Also,
Explanation:
Given, the radius of a nucleus is given as
.
where,
- A is the mass number of the nucleus.
The density of the nucleus is defined as the mass of the nucleus M per unit volume V.
For the nucleus 127 I,
Mass, M =
Mass number, A = 127.
Therefore, the density of the 127 I nucleus is given by
On comparing with the density of the solid iodine,
Yeah, it's every state. Atoms need a certain quanta of energy to jump to each state of energy, and therefore change state depending on how much energy is absorbed and/or released. This applies to all states of matter.
Answer:
When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.
Therefore the correct answer is a
Explanation:
In this exercise you are asked to identify the given sentence with a specific part of the scientific method.
Among the parts of the method we have.
* Independent variable . The controlled variable in research
*Dependent variable. The magnitude measured in the experiment
* Control variable. The magnitude that is not controlled
*Experiment. It is the design of the procedure to evaluate the hypothesis
* Hypothesis. It is the assumption with which scientific work begins
* Prediction. It is a consequence of work if the mortgage is correct.
When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.
Therefore the correct answer is a
