The common problem of traditional methods of showing relief on a map are of various types which are used by cartographers.

In a standard topographic map, Contour lines are the most used or common traditional method of showing relief and elevation. Therefore, contour a line appears as an imaginary line or lines on the ground, above the ground or as well as vertical distance above or below sea level. Note, all points on the contour lines are at the same elevation.

A cartographer can also use Layer tinting as a traditional method of showing relief on a map by the use of color. The application of different color is used for each band of elevation solely.

Also, a cartographer use each shade of band or color, to represents a definite elevation range. A legend can therefore be printed on the map margin to illustrate the elevation range that is represented by each color. Nevertheless, this method is not permissible to allow the map user to determine the exact elevation of a specific point.

The valid Hypothesis to support the statement is The speed of the Earth's rotation decreases as we move away from the equator due to the effect of Earth's latitude on the Coriolis force.

The Coriolis force is a result of the Earth's rotation and causes moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This force influences the rotation speed of the Earth and its effect is stronger near the poles compared to the equator.

Based on this, a valid hypothesis could be that the speed of the Earth's rotation decreases as we move away from the equator due to the increasing influence of the Coriolis force. As we move closer to the poles, the Coriolis force becomes more significant, causing a decrease in the speed of rotation.

This hypothesis suggests that the rotation speed at the equator is higher compared to regions closer to the poles. It is supported by the understanding of the Coriolis force and its impact on the Earth's rotation. Further investigation and analysis of data, such as measurements of rotational speed at different latitudes, would be needed to confirm or refute the hypothesis.

Friction during the rolling process helps to transfer the force from the rolling mill to the metal being rolled. Proper friction can help to ensure that the metal is uniformly compressed and shaped throughout the rolling process.

Friction also helps to remove any surface or subsurface defects from the metal, improving the quality of the final product.

Friction affects thickness in several ways. If the friction is too high, it can cause the metal to stick to the rolls, resulting in uneven thickness and possible tearing or ripping of the metal.

If the friction is too low, the metal may not be compressed enough, resulting in a thicker product than desired. The ideal amount of friction depends on factors such as the type of metal being rolled, the temperature of the metal, and the speed of the rolling process.

Answer:

Most of the time LIC's are self-employed (work in agriculture).

Explanation:

Therefor, people who live in LIC's mainly depend on the weather as most people who live in low income countries provide food, via farming. Climate change would cause a result of low food supply due to high levels of heat in the summer which could cause the crops to die due to lack of water; as dry soil conditions would cause reduction in the growth of crops, pasture and vegetation.

Pesticides have permitted agricultural production to expand without an increase in farmland. However, the leaching of pesticides from fields into local water tables, lakes, and streams might have harmful environmental and health implications.

To minimize leaching, environmental protection laws demand that pesticides have a half-life of less than 250 days.A half-life refers to the time it takes for a compound to decompose into half its original quantity. If it takes more than 250 days, the chemical will linger in the environment for an extended period of time. In this scenario, if you have a pesticide sample with a concentration of 0.2M/L from a local farmer and you measure the concentration to be 0.19M/L 25 days later, it is essential to know if the pesticide is in compliance with the regulation.

To check if the pesticide is in compliance with the regulation, calculate the half-life of the pesticide. Then use the half-life to determine if the pesticide is in compliance with the 250-day requirement.Let’s calculate the half-life of the pesticide: t½ = (25 days)/[ln(0.2 M/L)/ln(0.19 M/L)]t½ ≈ 130.9 daysSince the half-life of the pesticide is less than 250 days, the pesticide is in compliance with the regulation. Thus, the pesticide can be used.

Given that the regulatory requirement is 250 days, the half-life of the pesticide is less than 250 days, hence, the pesticide is in compliance with the regulation.

To determine if the pesticide is in compliance with the regulation, calculate the pesticide half-life.

The half-life of a pesticide is the amount of time it takes for half of the initial concentration to degrade.

Mathematically,

\(t1/2 = (ln 2) / k\)

where k is the rate constant for degradation.

Assuming first-order kinetics for pesticide degradation, the concentration of the pesticide at any time (t) can be described by the following equation

C = Co * e^(-kt)

where

Co is the initial concentration and

C is the concentration

t is time

k = (ln Co - ln C) / t

Substitute the given values

k = (ln 0.2 - ln 0.19) / 25 days

k = 0.0122 days^-1

Now we can calculate the half-life:

t1/2 = (ln 2) / k

t1/2 = (ln 2) / 0.0122 days^-1

t1/2 = 56.8 days

Since the half-life of the pesticide is less than the regulatory requirement of 250 days, the pesticide is in compliance with the regulation.
