Answer:
If your form is correct (b)
Iron atoms are heavier than gold atoms
Explanation:
Chart:
Materials Specific heat
Gold 0.129
Iron 0.45
The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1K.
We can see that the more the mass of a substance, the higher the specific heat needed to raise the temperature.
Specific heat is directly proportional to the mass of substance.
It also dependent on the amount of heat supplied and the nature of the substance.
- The mass of a body is the amount of substance it contains.
- A heavier substance has more number of atoms in it.
- Since iron has a higher specific it, the atoms must be heavier or more than that of gold.

That is a reason
Answer:
Qualitative, Quantitative, Qualitative, Quantitative, and Qualitative.
Explanation:
Answer:
i. The error is the rough convex mirror.
ii. This should be replaced with a smooth convex morror.
Explanation:
Reflection is dependent on the surface involved and has two types; diffuse and specular. When the surface is rough, diffused reflection is observed. The surface causes a distortion of the incident light (the rays would be reflected at different angles to one another) after reflection. This makes some rays to interfere with one another. While specular reflection is observed with a smooth surface.
In the statement, the rough convex mirror would produce a distorted reflection which would produce diffused reflection. The effect is that few or no rays (depending on the degree of how rough the surfce is) would be reflected to the other smooth, flat diagonal mirror.
