which types of materials have a molecular structure that makes them good conductors explain how understanding this relationship can help people design more efficient technologies​

Answers

Answer 1

Answer: Metals

Explanation:

The metals are the conductors of electricity. These are made up of atoms which conducts electricity in the form of electrons in the outer shell that can move freely. These take away the electric charge on the entire metallic system. This way the metal conducts electricity and can also pass electricity to other surfaces if come in their contact. Thus the metals are used for creating equipment of technological importance.

1. How would increasing the magnitude of the charges on two charged particles and decreasing the distance between the particles affect the strength of the electric force between the particles?

Answers

Answer:

Explanation:

Coulomb's law of electrostatics states that the Coulomb force between two charged objects is proportional to the size of the charges, and inversely proportional to the separation distance. The constant of proportionality is called Coulombs constant. In math words, it says:

\(F=kq_1q_2/r^2\)

If you decrease the magnitude of the charges, the total Coulomb force would also decrease. If the distance between the particles was decreased, the total Coulomb force would increase. A smaller term in the denotator would cause the Coulomb force to increase.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

What is the velocity?

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.  

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km  

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)

v = 1463.4 Km/hr

#SPJ2

The velocity of the vehicle can be calculated by dividing the distance traveled by the time taken:

Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s

To convert m/s to km/hr, we need to multiply the velocity by 3.6:

Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr

The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.

The resistance of the filament lamp is 88.235 Ohm.

Ohm's law states that - "The current through a conductor is proportional to the voltage across the conductor." This law holds true in the case of materials such as metals and the fact that the temperature remains constant. Non metals do not follow the Ohm's law. Here in the question, the data given is as follows V=4.5 V , I=51 mA. 51 mA has to be converted to SI unit which is 0.051 A. The unknown variable here is R. The formula of Ohm's law is V=IR.

Answers

Powering Your Home: Understanding Energy Resources in Dubai, United Arab Emirates

Dubai, one of the seven emirates of the United Arab Emirates, is a rapidly growing city with a population of over 3.3 million people. With the increase in population and development, the demand for electricity has also risen significantly. Have you ever wondered where the electricity that powers your home comes from? In this handout, we will provide you with information about the energy resources used to power the electrical grid in Dubai.

Nonrenewable Resources:

Dubai relies heavily on nonrenewable resources such as natural gas and oil to generate electricity. As per Dubai Electricity and Water Authority (DEWA), in 2020, 94% of the electricity generated in Dubai came from natural gas and 6% from coal.

Renewable Resources:

Dubai has been working to diversify its energy mix by investing in renewable resources. According to DEWA, 6% of Dubai's electricity in 2020 was generated from renewable sources, such as solar and waste-to-energy. DEWA has set a target to increase the share of renewable energy in Dubai's energy mix to 75% by 2050.

Nuclear Energy:

Dubai is also investing in nuclear energy to diversify its energy mix. The first nuclear power plant in the UAE, the Barakah Nuclear Energy Plant, started operations in 2020. It is expected to generate 5.6 GW of electricity and will contribute to reducing carbon emissions.

Most Used Renewable Resource:

Dubai has the world's largest single-site solar energy project, the Mohammed bin Rashid Al Maktoum Solar Park. It is a key component of Dubai's clean energy strategy, and its capacity is expected to reach 5 GW by 2030. The solar park uses photovoltaic solar panels to convert sunlight into electricity.

Interesting Fact:

Dubai is home to the world's tallest building, the Burj Khalifa, which has been designed to be energy-efficient. It uses a combination of technologies such as a high-performance glass facade, an efficient air-conditioning system, and a double-decker elevator system that reduces energy consumption by 20%.

Conclusion:

Dubai's energy mix is currently dominated by nonrenewable resources, with natural gas being the primary source of electricity generation. However, the city is making significant strides to increase the share of renewable energy and diversify its energy mix. By investing in nuclear energy and the Mohammed bin Rashid Al Maktoum Solar Park, Dubai is working towards achieving its goal of becoming a sustainable city and reducing its carbon footprint.

What would happen to the digestion process if enzymes were not present

Answers

Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.

Explanation:

I hope this helps

Enzymes play a critical role in digestion by breaking down large food molecules into smaller molecules that can be absorbed by the body. If enzymes were not present in the digestive process, the body would not be able to break down food effectively, leading to a number of negative consequences.
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

Read "Python Invasion" and answer the questions on the right.
Python Invasion!

By Leigh Driver


For years, the number-one, most feared animal in Florida has been the alligator. But recently the Burmese python has been challenging the alligators’ long-held position. Burmese pythons are native to Asia, but they have found a new home in Florida. Their numbers are increasing dramatically. Today they can be found in the wild and in suburbs across the state. Burmese pythons have lightly-colored skin with brown patches, and they are admired for their skin patterns and size. But they are also massive hunters--among the largest top six snakes in the world--and they pose a danger to people, other animals, and the environment.


How Did They Get There?


The Burmese python has become more and more popular as a house pet. This caused a surge of imports of the snake to Florida. This is not the first time Florida has become home to a species of reptile intended to be kept as a pet. The state is the adopted home of several types of reptiles. The green iguana and the speckled caiman, a type of alligator, were brought to Florida as family pets. Now, many of theses creatures live in the wild. These animals may seem like exotic and fascinating alternatives to the family cat, but they are very difficult to maintain. People often found them hard to keep at home, so they released them to the wild.

The same thing is happening with the Burmese python, an animal that begins at a manageable three feet long on average but can grow up to 20 feet long and weigh up to 250 pounds. There have been several reports of deaths in homes where pythons are kept. When a python is fully grown, many owners find they can no longer handle their exotic reptile, and they simply release it outdoors.

Another factor has been the destructive hurricanes that Florida has suffered over the years. Sometimes storms damage pet stores and animal shelters, and the reptiles get loose. When people bring their other pets to shelters, it is sometimes easier to free the snakes because of overcrowding.

Environmental Impact

A python can survive very well in the Florida climate. In fact, the Florida Everglades are the perfect home for these snakes. Some experts estimate that there are up to 100,000 Burmese pythons living in the Everglades alone. But this surge of wild pythons is not without problems.

Releasing animals into an environment where they do not belong affects that environment and the species within it. Such animal populations are referred to as a non-native species. While few creatures prey on it, the python competes with other animals in the territory. For example, alligators compete for prey with pythons. As these snakes breed and thrive, they threaten the survival of the alligators. Other animal populations may also be harmed by the presence of pythons, and Floridians who are concerned about conservation have publicized the dangers of this situation.

Danger to People


Another growing concern is that the Burmese python can seriously harm people. A python can eat an animal as large as a full-grown deer, and it is extremely difficult to control the powerful creature. Some Floridians believe that keeping these snakes as pets is simply not safe.






What Can Be Done?

Scientists and citizens have become more and more worried about the “invasion” of the Burmese python into the Florida wild. There have been proposals to ban the importation of snakes or to make it illegal to keep these animals as pets, but so far no laws have been passed. Some have even proposed destroying the pythons living in the Everglades to get rid of the problem.
