Correct Answer: B. the gold nucleus is positively charged and is concentrated in a tiny volume

Explanation

The Rutherford scattering experiment led to the development of the nuclear model of the atom. Here's why:

1. Observation: A beam of positively charged alpha particles was fired at a thin gold foil.

* Most alpha particles passed straight through, indicating that atoms are mostly empty space.

* A small fraction of alpha particles were deflected at very large angles, some even bouncing straight back.

2. Interpretation: For a positively charged alpha particle to be strongly deflected or repelled, it must have encountered a very dense, positively charged region within the atom. The fact that only a tiny fraction were strongly deflected implied that this dense, positively charged region must be extremely small compared to the overall size of the atom. This small, dense, positively charged region was named the nucleus.

Let's evaluate the options:

• A. a gold nucleus contains protons, neutrons and electrons uniformly distributed in a tiny volume: This is incorrect. Electrons are outside the nucleus, and the idea of uniform distribution within the atom was disproven by the experiment (which showed mostly empty space). The existence of neutrons was discovered later.

• B. the gold nucleus is positively charged and is concentrated in a tiny volume: This perfectly matches the conclusions drawn from the experiment. The positive charge explained the repulsion of alpha particles, and the tiny volume explained why most particles passed through unaffected.

• C. the gold nucleus emitted alpha particles: The experiment involved *firing* alpha particles *at* the gold film, not the gold nucleus *emitting* alpha particles. While some nuclei undergo alpha decay, that's not what this experiment demonstrated.

• D. the gold nucleus is concentrated in a tiny volume and contains alpha particles: While the nucleus is concentrated in a tiny volume, the experiment did not directly conclude that the nucleus contains alpha particles as fundamental constituents. It established the existence of a positively charged, dense core. The specific composition (protons and neutrons) and the concept of alpha particles as helium nuclei came with further discoveries. Option B is a more direct and accurate conclusion based *solely* on the scattering observations.

Therefore, the experiment showed that the gold nucleus is positively charged and concentrated in a tiny volume.

The final answer is B

Explanation

(a) Different types of business environments are:

(i) Economic environment (ii) Industrial environment (iii) Socio -cultural (iv) Demographic (v) Technological (vi) Legal. (vii) Political (viii) Physical (ix) Climatic.

(b) Companies continue to advertise inspite of criticism because:

(i) Advertising leads to and induces purchases and greater sales volume.

(ii) Advertising creates awareness about the existence of a product.

(iii) Advertising affords the producer the opportunity of explaining the uses and features of his products.

(iv) It informs the people about the place and price of obtaining the goods.

(v) Advertising leads to mass production as a result of increase in sales.

(vi) It arouses the interest of the consumers in a particular product.

(vii) It helps to make brand names of goods known to members of the public.

(viii) The public are informed of any changes in the name or uses of the good.

Correct Answer: A. do

Correct Answer: C) it is determined by both demand and supply forces

Explanation

The question is asking what happens to the quantity of good X that is actually exchanged when the market for good X is in disequilibrium. Disequilibrium means that the demand and supply forces in the market are not balanced, which can result in either a shortage or a surplus of the good.

Option A suggests that the quantity of good X that is actually exchanged is solely determined by the forces of demand. However, this is not necessarily true as the supply side also plays a role in determining the quantity of good X that is actually exchanged.

Option B suggests that the quantity of good X that is actually exchanged is solely determined by the forces of supply. However, this is also not necessarily true as the demand side also plays a role in determining the quantity of good X that is actually exchanged.

Option C, which is the correct answer, suggests that the quantity of good X that is actually exchanged is determined by both the demand and supply forces. When the market for good X is in disequilibrium, the quantity of good X that is actually exchanged will be determined by the side with the stronger force, which can either be demand or supply.

Option D suggests that the quantity of good X that is actually exchanged is determined by the forces of demand or supply, whichever is shorter. This option is not correct as the quantity of good X that is actually exchanged is not determined by the shorter side but rather by the side with the stronger force.

In summary, when the market for good X is in disequilibrium, the quantity of good X that is actually exchanged is determined by both demand and supply forces, with the side having the stronger force determining the quantity of good X that is actually exchanged.
