What rules discoverable by reason did Enlightenment thinkers try to apply to the study of human behavior and society?

User Avatar

Asked by Wiki User

Enlightenment thinkers sought to apply rational principles and the scientific method to the study of human behavior and society. They emphasized the importance of empiricism, reason, and universal laws in understanding and improving social interactions and institutions. By grounding their analyses in logic and evidence, they aimed to uncover objective truths about human nature and society.

Explain how advancements in the field of science during the Enlightenment led to new ideas about human behavior and society and eventually changed the way people view government and its role?

User Avatar

Asked by Wiki User

Advancements in science during the Enlightenment, such as Newton's laws of motion and the scientific method, promoted the idea of natural laws governing the universe, which led to a shift in thinking about human behavior and society. This shift emphasized reason, individual rights, and the pursuit of knowledge. These ideas challenged traditional notions of government based on divine right and absolute authority, paving the way for new forms of government that prioritized individual rights and the consent of the governed, ultimately shaping modern ideas of democracy and the role of government.

Why is fire striking a match an artificial source of light?

User Avatar

Asked by Wiki User

i am definitely no expert as I'm in grade six, yet i think that it is artificial because the fire (natural as it is) is created by the chemical reaction when the box and match are struck together, therefor, quite unnatural in my opinion. You don't need to quote me on this, to gather your own opinion just think about if a match would work and even exist if we didn't exist either!

Why is a solar water heater not so efficient on a cloudy day?

User Avatar

Asked by Wiki User

A solar water heater's efficiency is notably affected on cloudy days due to reduced sunlight exposure and intensity. Several factors contribute to this decrease in efficiency:

Sunlight Availability: Cloud cover diminishes the amount of sunlight reaching the solar panels of a water heater. Solar panels require direct sunlight to generate sufficient heat for water heating. When clouds obstruct sunlight, the panels receive diffused or scattered light, reducing their energy absorption and heat production capabilities.

Solar Irradiance: Cloudy conditions result in lower solar irradiance, which refers to the amount of solar energy per unit area reaching the Earth's surface. Reduced solar irradiance directly impacts the energy output of solar panels, leading to decreased heating efficiency in solar water heaters.

Temperature Differential: Solar water heaters operate based on the temperature difference between the solar collector (where water is heated) and the storage tank. Cloudy weather leads to cooler ambient temperatures, affecting the overall temperature differential and slowing down the heating process.

Cloud Thickness and Density: The thickness and density of cloud cover further influences solar water heater efficiency. Thick and dense clouds block more sunlight, resulting in a more significant reduction in heating performance compared to thin or scattered clouds.

Time of Day and Seasonal Variations: The time of day and seasonal changes also impact solar water heater efficiency. Cloudy mornings or evenings may have lower solar energy availability, affecting heating performance. Additionally, seasonal variations in cloud cover and sunlight duration can influence overall system efficiency throughout the year.

Despite reduced efficiency on cloudy days, modern solar water heaters often incorporate backup heating systems, such as electric or gas heaters, to ensure a continuous hot water supply. This hybrid approach mitigates the impact of cloudy weather on water heating, providing reliable hot water even during periods of limited sunlight.

To optimize solar water heater efficiency, homeowners can consider factors like system orientation, tilt angle, shading prevention, and regular maintenance to maximize sunlight exposure and heat absorption capacity, thereby enhancing overall system performance and energy savings.

What would happen if you lit a hazelnut on fire?

User Avatar

Asked by Wiki User

If you lit a hazelnut on fire, it would undergo combustion, producing flames and releasing heat. The nut's outer shell and oils within would contribute to the burning process, resulting in a small, relatively short-lived flame.

Energy cannot be saved.!!!!

However, physical or chemical sources can release more or less energy as appropriate.

This release is then transferred ( the energy) to another form/source.

NCV and GCV of coal?

User Avatar

Asked by Wiki User

net calorific value and gross calorific value

GCV to NCV conversion:

- Using the following IPCC formulae determine the NCV of those fortnightly samples

- NCV = GCV - 0.212H - 0.0245M - 0.0008O

- Where H - Percentage of Hydrogen, M - Percentage of Moisture and O - Percentage of Oxygen (as determined from the ultimate analysis report)

- Please note that here GCV and NCV are in Mega Joule/kg, therefore it is required to do the necessary unit adjustments (1kcal/kg = (4.186/10^3) = 0.004186 MJ/kg)

Assuming GCV = 18.4017MJ/kg, O =9.23%, H = 3.63%, M=7.45% (Source: Coal analysis report conducted independent testing laboratory - ' National Council for cement and building materials')

What are the disadvantages of using petroleum as fuel?

User Avatar

Asked by Wiki User

(Another contributor wrote:)

Petroleum is a fossil fuel. Fossil fuels have many disadvantages:

  1. They add carbon to the atmosphere, causing global warming.
  2. They are very limited in quantity and become more expensive to find and refine.
  3. They are biologically hazardous and can pollute ground and water

One is that we use fossil fuels for like running our cars and providing electricity. So we use them for important things, but one day we will run out of fossil fuels and we will have to find replacements. In some places they do use things like windmills and water generator for electricity, but most places rely on them.

Another is that using fossil fuels is bad for the environment, and the pollution is causing global warming and climate change.

How can algae be used as a fuel source?

User Avatar

Asked by Wiki User

Algae fuel is any fuel made using algae. Algae are a type of simple organism, of which most are photosynthetic (they get their energy from the sun). The smallest algae are unicellular, the largest are the seaweeds that make up kelp forests.

Some types of algae use sunlight to make oil, and if these algae are harvested and the oil extracted from them, the oil can be used in a variety of ways, including as a replacement for petroleum derived diesel fuel.

Whatever portion of the algae which is not oil, is carbohydrates and proteins. These carbohydrates and proteins can be processed to produce butanol, a oily, energy-dense alcohol, which can be used as a direct gasoline substitute.

The oil from algae can also be converted (using the same processes that are used on petroleum) into other types of fuel, such as biogasoline, and aviation biofuel.

The non-oil components of algae can also be converted to other fuels besides butanol (although that's one of the most valuable producable fuels), such as methane and ethanol.

How much energy does the energy-efficient computer save?

User Avatar

Asked by Wiki User

If no, or few, applications are left up and running a computer will not consume much power when left on. Computers in general consume less power then a single light bulb when running. At idle they may go down to as little as 30 watts depending on age, speed and configuration of the computer.

How far can electricity travel in water?

User Avatar

Asked by Wiki User

Voltage does not run through power lines. If it did, then birds would be killed instantly

as soon as they sat on a power line.

Voltage is the difference in potential between two things. In the case of power

lines, it may be between the two wires in an extension cord, or between one wire

and the Earth. The bird is fine, because both of his feet are on the same wire, and

there's no difference in potential between them.

The utility lines that enter your house measure 110 volts, 220 volts, or 480 volts

compared to the Earth. When you plug a lamp, a cellphone charger, or a radio into

an ordinary outlet in your house, there is typically 110 volts between the two prongs

of the plug.

The primary line that runs down the street along the very top of the poles measures

2400 volts, 4800 volts, or 7200 volts compared to the Earth.

The heavy cables that carry power from the generating stations to the distribution

substations, or intercity along the large transmission towers, measure several tens

of thousands of volts compared to the Earth.

Where do you get the energy star certification for appliances?

User Avatar

Asked by Logansnana

The Energy Star certification comes with the appliance from the factory. If it passes all tests for efficiency, it is Energy Star Rated. If it doesn't it isn't. You can't get an Energy Star rating for an appliance that left the factory without one. It isn't something that can be bought, it can only be earned.
