why is it difficult for a car to round a curve at high speed
Answers
Answer:
Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.
Answer:
Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.

How do we know there has not been an increase in the number of earthquakes? Officials from the U.S. Geological Survey, the government agency that keeps track of earthquakes, point to statistics. On average, there have been no more earthquakes so far in 2010 than there were in previous years.
What Happens During Earthquakes?
In reality, it's not the number of quakes that has gained our attention, but the devastating impact quakes can have. Earthquakes are very natural—it's inevitable that they'll happen because of the way the planet works. The earth's surface is made up of tectonic plates that fit together like puzzle pieces and are always moving past each other. When two of the plates' edges get caught, stress builds up at the fault line—the crack between the plates. When the plates are finally able to break free of each other, the stress is released, and an earthquake occurs. Earthquakes of varying strengths happen every day, usually at fault lines. Some of these quakes have a high magnitude, while others are relatively weak. But it's often where an earthquake takes place that determines whether it will be something that goes largely unnoticed, or a disaster that affects thousands of people.
What Is Changing?
In the past, earthquakes were not as much of a problem because Earth's population was smaller, and cities were less populated.
"Look at some of the big [earthquakes] recently," said Debarati Guha-Sapir of the World Health Organization. Guha-Sapir cited some earthquakes that took place in areas where the population had increased in recent years, making the quakes more serious. "Had the Izmit or Bhuj quakes [of 1999 and 2001] happened 30 years ago, the events would have been relatively insignificant, as the [populations] of these cities were a third of what [they were when the earthquakes happened]. Increasing population density makes a small event into a big one."
Some of the earthquakes that took place in early 2010 occurred in highly populated areas, as well. More people are moving into megacities that happen to be built on fault lines—and many cities are on fault lines. Of the 130 cities with more than one million people, more than half are in earthquake zones, making them more prone to earthquakes.
In many of these cities, officials have drawn up laws requiring that buildings be designed and constructed to endure earthquakes. But some cities, particularly those in developing countries, lack the resources to do this. There, people are rapidly putting up substandard buildings that can't withstand the force of the shaking earth. For example, the Haiti earthquake took place near the nation's crowded capital. There was a great deal of destruction because there were "too many people crammed into a city that wasn't meant to have that many people and have an earthquake," said University of Miami geologist Tim Dixon.
Another reason quakes seem worse is that we're paying more attention. Everyone noticed when the Haiti earthquake was quickly followed by the Chile earthquake. Many people watched the news and the Internet for updates on these disasters, unable to believe that they were seeing two major earthquakes in such a short period of time. But eventually, the earth will have a period when earthquakes are minor or in unpopulated areas. Then people won't notice quite so much anymore.
"People are paying attention to the violent planet we've always lived in," said Dennis Mileti, a seismic researcher. "Come back [at a time when] there have been no [noticeable] earthquakes, [and] most people will have forgotten [about them] again."
According to the article, what is one reason why it seems as if the world is experiencing more earthquakes than usual?

Explanation: there was not on now 2023, 2022, 2021, 2020, and 2019

Answers
Answer:
Describe how light travels from the sky to the viewer's eye. First, light from the sky travels into the concave mirror, which reflects the light to a smaller and flat mirror. Then, the small mirror reflects that light into the telescope's magnifying lens. This lens makes the light reach the viewer's eyes.

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.

Answers
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

Darker colors absorb heat, While lighter colors don't. If a house is painted black in Arizona, The black color will absorb the heat making the temperature inside the house very hot even with the AC on. If a house in Arizona is painted White, The heat will bounce off the White color, making the temperature inside the house cooler.
Hope this helps!
Answer:
Have you ever noticed people working outside in the hot sun and how you never really see them wearing black shirts or pants. This is because dark colors absorb heat, however light colors, such as white, do the exact opposite. Instead of absorbing the heat from the light, light colors reflect it. So people usually paint there houses lighter colors in hot places to keep their there houses from absorbing heat so it does not cost them so much on electricity bills for air conditioning.

Here's the answer that Vivianmoore2006 put from the other question
(I Copy and Pasted it all from the other question) Please give them full credit.
----------------------------------------------------------------------------------------------------------
Here is every answer for analog and digital (in order)
Analog:
Signal Shape: Smooth and continuous
Numerical Values for Signal Measurements: Analog signals represent one continuous variable as the result of another continuous time-based variable. They are capable of outputting continuous information with a theoretically infinite number of possible values.
Amount of Data that can be transmitted: analog circuits can conduct only fairly low-speed data communications. The maximum data rate over an analog facility is 33.6K bps when there are analog loops at either end. With 56K bps modems, only one end of the loop can be analog. The other end of the connection has to be digital.
Energy requirements: light, sound, temperature, position, and pressure
Privacy and security (ability of the signal to be encoded in a secret code): not encrypted
Clarity of Signal: noise affects clarity and quality, noise is amplified, amplified noise causes more random information in the signal, signal bandwidth is low
Digital (in order):
Signal shape: stepping, square, and discrete
Numerical Values for Signal Measurements: digital communication methods transmit a complete measured value, in other words both a numeric value and a unit of measurement
Amount of data that can be transmitted: First of all, it is theoretically possible to transmit digital signals directly. Unfortunately when we use capacitors and inductors (energy storage devices) to match the impedance from the transmitter to the air (low impedance transistor say 5 ohms to 388 ohms (air)) these components introduce a bandwidth limiting match. Since all impulse functions have infinite bandwidth (transmitting a 1 and a zero) the bandwidth of the transceiver must be multi octave in order to have any reasonable efficiency. Systems engineers simplify the problem by introducing direct sequence modulation where a carrier is modulated 0/180 degrees dependent on the data rate.
Energy requirements: voltage, acoustic pressure, and magnetization of a magnetic storage media
Privacy and security: encrypted
Clarity of signal: noise is lower in amplitude, electronics can ignore the noise, quality of signal is maintained, signal is high
