Answer: Option (a) is the correct answer.

Explanation:

J.J. Thomson is a renowned scientist who discovered the model of atom which is known as the plum pudding model.

Through this model Thomson stated that an atom consists of small particles. These small particles are positive and negative charges present inside an atom.

Whereas Democritus stated that an atom is indivisible and thus he proposed the indivisible atom model.

Ernest Rutherford discovered that an atom has lot of empty space and this space is nucleus. As he stated that positively charged particles are known as protons which are present inside a nucleus.

Rutherford's gold foil experiment discovered that an atom has nucleus in which most of the mass of an atom is concentrated.

Thus, we can conclude that the plum pudding model was proposed as a result of J. J. Thomson’s work.

Which of the following sets represents a pair of isotopes?
son4ous [18]
The correct option is A,
Isotopes are atoms of an element, which have the same number of protons but different number of neutrons in the nucleus of the atom. Thus, isotopes have the same atomic number but different mass number.
Looking at the options given above, you will discover that Chlorine which is given in option A is correct. Both type of chlorine has the same atomic number, which is 17, but they have different atomic masses, the atomic mass of the first one is 35 while that of the second one is 37.<span />

Density of a piece of wood that has a measurement of 24 cm3 and 768 g
Brut [27]

Answer:

<h3>The answer is 32 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 768 g

volume = 24 cm³

We have

density =  \frac{768}{24}  \\

We have the final answer as

<h3>32 g/cm³</h3>

Hope this helps you

Scientist can use trees to look at climates of the past. How? What information can they gather and how do they gather it? Explai
andrezito [222]

Explanation:

Scientist use trees a whole lot to look at climate of the past by examining tree rings.

These are layers of cambium in each successive years formed. They have an annual growth pattern and are known as tree rings.

Tree rings can be used to decipher the age of a tree.

  • These three rings can be used to interpret climatic patterns.
  • During a wet climate, the tree rings are more robust and bigger.
  • In a dry climate, the rings are thinner.
  • These alternating patterns can be used to decipher the climatic signatures in a tree.
  • Sometimes, it is possible to evaluate some certain isotopes that are useful in climatic studies.
