Secondary enrichment is an important ore forming procedure. This process is known to be secondary because of the fact that in this case the valuable ore minerals do not directly precipitate from a cooling magma.

In this process ore deposits which are exposed to the ground surface, are weathered just as other rocks. When the ore minerals come in contact to the atmospheric oxygen, it gets oxidized and this oxidized forms are readily soluble in the water.

This solution with high concentration of many valuable materials start its journey downwards. As it gets down, it loses some of its dissolved materials in the surrounding areas and forms the Colorful oxidized zone below the surface.

As the solution leaks further downward and reaches the groundwater table the conditions suddenly changes from oxidizing to reducing. In this circumstances the dissolved materials in the leaking water precipitates and forms secondary sulfide deposits.

From the above discussion the points given in the question can be arranged in the following manner:

1) Igneous activity ceases after producing ore bearing deposits.

2) The bearing deposit cools entirely.

3) Groundwater flows through an ore deposit and leaches out material.

4) New ore minerals are precipitated in new locations.

Minimum initial velocity is 9.76 m/s and the corresponding angle is 58.3° is at which ball must be kicked in order for it to cross over the 3m high fence.

Velocity is the rate at which an object's location is changing as perceived from a particular point of view and as measured by a certain unit of time. It is the direction speed of an object in motion. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that analyzes how bodies move. Being a physical vector quantity, velocity must have both a magnitude and a direction in order to be defined. The scalar absolute value magnitude of velocity is referred to as speed, and it is measured in the SI metric system as metres per second (m/s), which is a coherently derived unit. An object must move at a constant speed in the same direction to have a constant velocity.

if the maximum load capacity (or buckling load) of column 1 (fixed-fixed) is 100 kn, the load capacity (or buckling load) of column 2 (fixed-free) will be = 1.56kN.

Buckling is simply the out-of-plane bending of a vertical compression member. The slenderness of the vertical compression member is typically to blame. This phenomenon is clearly explained by Euler, who has provided elaborate formulas to determine the actual amount of buckling in the compression member.

The compression member may be a column (long, short, or medium), a built-up steel member with a slender web, a readily available steel member with a slender web, etc. For various support situations, different buckling conditions exist. The terms "buckling load" and "crushing load" are interchangeable. We must fortify the slender member to prevent buckling.

Architects must consider the availability and cost of building materials when they plan their projects.

Building planning and design are the expertise of an architect, who typically has a significant impact on how a building is built. The art and science of building design are fields in which architects have extensive training. Architects need to be licenced professionally because they are in charge of ensuring the security of the people who use their buildings.

The Greek term for "chief builder" is the origin of the word "architect." Between the craftsman who designed a building and the one who actually built it, there was no distinction for a large portion of history.

Buildings could then be planned much more thoroughly before being built thanks to the development of linear perspective drawing in the 1500s, which made it possible to accurately depict three-dimensional structures in two dimensions.

Explanation:

Symmetry and rigid transformations are related in that symmetry is a type of rigid transformation. A rigid transformation is a type of transformation in geometry in which the shape of an object is preserved after the transformation is applied. This means that the distances between all points on the object remain the same, and the angles between those points are also unchanged.

Symmetry is a specific type of rigid transformation that involves a reflection, rotation, or translation of an object such that the resulting image is congruent to the original. In other words, symmetry is a type of transformation in which an object is mapped onto itself in a way that preserves its shape and size.

For example, if an object has rotational symmetry, it means that it can be rotated by a certain angle and the resulting image will be congruent to the original. If an object has reflectional symmetry, it means that it can be reflected across a certain line and the resulting image will be congruent to the original.

Overall, symmetry is a type of rigid transformation in which an object is mapped onto itself in a way that preserves its shape and size. This type of transformation is related to other types of rigid transformations, such as rotations and translations, which also preserve the shape and size of an object.

[tex]p_3[/tex] = water density = 1000 kg/m^3
