In order to calculate the SAA, it is help to start by calculating the zenith angle which is the angle between the Sun and the point directly overhead at solar noon. To determine the zenith angle, subtract the solar declination from the location latitude. If either the declination or location is in the Southern Hemisphere, assign it a negative value. Always report the absolute value of the calculated zenith angle (no negative zenith angles).

Zenith angle = (Location latitude) – (Solar declination)

Lastly, in order to calculate the SAA, simple subtract the zenith angle from 90°. Remember that the SAA is an angle, so do not label the SAA with North or South.

Example:

Las Vegas, Nevada (36°N) on December 21 (23.5°S solar declination)

Zenith angle = 36° - (-23.5°)

Zenith angle = 36° + 23.5°

Zenith angle = 59.5°

SAA = 90° - 59.5°

SAA = 30.5°

Q13. Calculate the zenith angles and solar altitude angles for the following locations at the specified dates. Recall the dates of the solstices and equinoxes in order to determine the solar declination for each of the dates listed. Replace the question marks with the related answers.

Answers

Answer 1

a) Honolulu, Hawaii (21.3°N) on June 21st (23.5°N solar declination)

Zenith angle = 21.3° - 23.5° = -2.2° (absolute value is 2.2°)

Solar altitude angle = 90° - 2.2° = 87.8°

b) Rio de Janeiro, Brazil (22.9°S) on December 21st (23.5°S solar declination)

Zenith angle = -22.9° - (-23.5°) = 0.6°

Solar altitude angle = 90° - 0.6° = 89.4°

c) Cairo, Egypt (30.0°N) on March 21st (0° solar declination)

Zenith angle = 30.0° - 0° = 30.0°

Solar altitude angle = 90° - 30.0° = 60.0°

d) Sydney, Australia (33.9°S) on September 23rd (0° solar declination)

Zenith angle = -33.9° - 0° = 33.9°

Solar altitude angle = 90° - 33.9° = 56.1°

Answers

Complete question:

The average of two number is 55. If 2 is subtracted from the greater number, the ratio between the numbers become 1:2 . The smaller number is

Answer:

The smaller number is 36

Explanation:

let the smaller number = x

let the greater number = y

\(\frac{x + y}{2} = 55\\\\\)

x + y = 110

y = 110 - x --------- equation (i)

\(\frac{x}{y-2} = \frac{1}{2}\\\\ y-2 = 2x\\\\y = 2x + 2 ------equation(ii)\)

Substitute y in equation (ii)

110 - x = 2x + 2

110 - 2 = 2x + x

108 = 3x

x = 108 / 3

x = 36

Therefore, the smaller number is 36

what is the effect of drainage basin and catchment area on people​

Answers

The drainage basin and catchment area have significant effects on people via water supply, flood control, provision of ecosystem services, and land use planning considerations.

The drainage basin and catchment area, which refer to the geographical region where water drains into a specific water body, have several effects on people.

Water supply: The drainage basin and catchment area play a crucial role in providing a source of water for human use. Rivers and streams within these areas serve as freshwater sources for drinking, irrigation, and industrial purposes. People living within or near these regions depend on the water resources for their daily needs.

Flood control: The topography and land characteristics of a drainage basin affect the potential for flooding. The shape and slope of the catchment area determine how quickly water drains, which can either mitigate or exacerbate flooding risks. Communities residing in these areas need to consider flood control measures and infrastructure to protect lives and property.

Ecosystem services: Drainage basins and catchment areas support diverse ecosystems, including forests, wetlands, and wildlife habitats. These ecosystems provide essential services like water filtration, carbon sequestration, and recreational opportunities. People benefit from these services, such as clean drinking water, climate regulation, and recreational activities like fishing, hiking, and wildlife observation.

Land use planning: Understanding the boundaries of a drainage basin and catchment area helps in land use planning and resource management. It allows policymakers and communities to make informed decisions regarding land development, agriculture, and conservation practices. Proper land use planning in these areas can contribute to sustainable development and minimize negative impacts on the environment and human well-being.

In summary, the drainage basin and catchment area have direct effects on people through water supply, flood control, provision of ecosystem services, and land use planning considerations. Recognizing and managing these effects are crucial for sustainable water resource management and the well-being of communities.

Answer: The answer is a  mixture of minerals. Thus, option B is the correct answer.

Explanation: Rocks are naturally occurring substances that are aggregates of minerals. It is a solid mass and its mineral composition gives it a distinct quality. They are mostly inorganic in nature however, they can be organic at times. For example, a semi-decomposed plant that has turned into coal.  The mineral composition of rocks is not fixed. It can either be made of a single mineral or it can be made of a combination of different minerals. Rocks are further classified as igneous, metamorphic, and sedimentary rock on the basis of their origin.

https://brainly.com/question/11802729

A mixture of minerals is the phrase that best describes a rock. Rocks are aggregates of minerals that are produced naturally. Thus, option B is correct.

Rock is a solid mass with a unique character due to its mineral makeup. They are mostly inorganic in nature, but occasionally they can be. For instance, a plant that has partially decomposed and becomes coal.  Rocks' mineral makeup can change over time. It can either be created from a single mineral or from a variety of minerals together.

Depending on where they came from, rocks are further divided into igneous, metamorphic, and sedimentary categories. Mineral grains mixed in diverse ways and with varying qualities make up the rocks. Minerals are chemical substances that exist in nature and have atoms organized in three dimensions. Therefore, due to their composition rocks are compared to minerals.

Therefore, option B is the ideal selection.

Answers

With the aid of diagram (source given below) that is attached, the formation of spring are:

(i) As a result of permeable and impermeable rock strata

(ii) Spring formed as a result of a d/y/ke or s/il/l intrusion:

How does Spring Form?

(i) In terms of permeable and impermeable rock strata:

Water can flow out of the ground when it reaches the surface where there are rocks that allow water to pass through them and rocks that don't. This usually happens when it rains and some of the water goes into the ground because of gravity. The water goes down through rocks that let it pass until it reaches a layer that doesn't let it pass. If there is a place where water can come out of the ground near where the two layers of soil that let water through and don't let water through meet, then it can flow out as a spring.

(ii) In terms of Spring formed as a result of a dy//ke or sill intrusion:

This is when a volcano pushes hot liquid rock into a crack in the ground and it hardens to form a straight or horizontal rock formation. The d/y/ke/sil/l can go through a layer of rock that allows water to pass through it. When it rains, some of the water goes into the ground and moves down because of gravity.The water goes down through rocks that can let water through until it hits a layer that won't let water through.  This forms groundwater. The underground water can be stopped or held back by a barrier like a wall or a mound. This blockage takes up space below the ground and can make the water level rise up to the surface of the earth. When the water underground reaches the ground level, it comes out quickly as a spring.

Final answer:

Springs follow Hooke's Law - they exert a restoring force against deformation and convert kinetic energy to potential energy and vice versa in this process. This ability allows them to return to their equilibrium state after being deformed.

Explanation:

A spring is formed by a specific atomic structure that restores its shape when deformed, this being a phenomenon driven by Hooke's Law. When you apply force to a spring, to stretch or compress it, you change its structure and its internal energy. This internal energy is often described as potential energy, while the energy involved in the spring's movement is the kinetic energy.

When you stretch or compress a spring, it exerts a restoring force that works to bring it back to its equilibrium state, and this process involves the conversion of kinetic energy to potential energy and vice versa. In relation to the spring's displacement from its equilibrium state, a term often used in physics, the force exerted by the spring can be calculated using Hooke's law, Fx = −kx.

Also, the spring's potential energy can be calculated using the formula U = kx². This conservation of energy principle allows the energy system involving the spring to remain constant even as the spring oscillates back and forth. The whole process is integrally relevant to understanding how springs work and how energy is conserved in a system involving springs.
