Why do bushfires often start during lightning storms?
Lightning starts by a Thunder storm. Thunderstorms always come with a lot of wind. The wind starts to rub the surface of the ground and buildings. This action brings the electrons to the clouds. The ground becomes positively charged and the bottom of the cloud becomes negative and upper part becomes positive. Since clouds are better conductors than air, the clouds start to build up charges. This causes the lightning. Once lightning hits a tree, or another object, not just the ground, then the current moves through the tree and continues to spread horizontally.

A single stroke of lightning can reach a temperature of 30,500oC, or five times hotter than the Sun's surface. If lightning strikes dry vegetation, this heat energy can start bushfires.

What Time of year is hail most likely to occur?
Hail is most likely to occur during the spring and summer months when warm, moist air near the ground rises rapidly into colder regions of the atmosphere. This rapid upward movement of air creates strong updrafts that can cause water droplets to freeze and form hailstones.
How often does the Sears Tower get struck by lightning?
The Sears Tower, now called the Willis Tower, is struck by lightning an average of 20-25 times per year. This is because of its height and location in Chicago, which experiences frequent thunderstorms. The tower's lightning rods help to protect it from damage during strikes.
What is the sound of the thunder in words?
The sound of thunder is often described as a loud rumble or booming noise. It can vary in intensity and duration, with some likening it to a roaring or rolling sound.
What are high frequency waves observed in which layer?
Radio propagation describes how radio waves behave when they are transmitted, or are propagated from one point on the Earth to another.[1] Like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization and scattering.[2]
Radio propagation is affected by the daily changes of water vapor in the troposphere and ionization in the upper atmosphere, due to the Sun. Understanding the effects of varying conditions on radio propagation has many practical applications, from choosing frequencies for international shortwave broadcasters, to designing reliable mobile telephone systems, to radio navigation, to operation of radar systems. Radio propagation is also affected by several other factors determined by its path from point to point. This path can be a direct line of sight path or an over-the-horizon path aided by refraction in the ionosphere. Factors influencing ionospheric radio signal propagation can include sporadic-E, spread-F, solar flares, geomagnetic storms, ionospheric layer tilts, and solar proton events.
Radio waves at different frequencies propagate in different ways. The interaction of radio waves with the ionized regions of the atmosphere makes radio propagation more complex to predict and analyze than in free space. Ionospheric radio propagation has a strong connection to space weather. A sudden ionospheric disturbance or shortwave fadeout is observed when the x-rays associated with a solar flare ionize the ionospheric D-region. Enhanced ionization in that region increases the absorption of radio signals passing through it. During the strongest solar x-ray flares, complete absorption of virtually all ionospherically propagated radio signals in the sunlit hemisphere can occur. These solar flares can disrupt HF radio propagation and affect GPS accuracy.
Predictions of the average propagation conditions were needed and made during the Second world war. A most detailed code developed by Karl Rawer was applied in the German Wehrmacht, and after the war by the French Navy.
Since radio propagation is not fully predictable, such services as emergency locator transmitters, in-flight communication with ocean-crossing aircraft, and some televisionbroadcasting have been moved to communications satellites. A satellite link, though expensive, can offer highly predictable and stable line of sight coverage of a given area.
What does it mean when the sky is yellow during a thunder storm?
The sky can change various colors depending on whether its night or day. During a thunderstorm the sky will change to a bright illuminating yellow or orange when its a severe storm. The reason behind that is actually unknown. However some experts say its depending on the heated temperature high up in the atmosphere that storms can actually cause many different storm colored skies. For instance, tornadoes usually can cause a green yellowish color when approaching.
What happens when lightning hits oil?
When lightning hits oil, the intense heat can cause the oil to quickly vaporize and potentially combust, leading to a fire. The presence of oil can also increase the risk of a larger and more intense fire following a lightning strike due to its flammable nature. It is important to have proper safety measures in place to minimize the risk of fire when lightning strikes near oil storage or production facilities.
What to do for a dog been struck by lighting?
If a dog is struck by lightning, seek immediate veterinary attention as there may be internal injuries or shock. Keep the dog calm and monitor for signs of respiratory distress or cardiac arrest. Do not attempt to administer first aid without proper training to avoid causing further harm.
Is it more likely for people to get hit by lightning or not?
The tallest person or object is more likely to get struck than anything else. But don't get me wrong anything can get struck by lightning. and if you wear rubber soles you more likely not to get struck.
Why the amplitude doesn't depend on frequency and time period?
The amplitude of a wave is determined by the energy of the wave, which is not affected by the frequency or time period. The frequency and time period of a wave only determine how many cycles occur in a given time frame, not the strength of each individual cycle. Therefore, the amplitude remains constant regardless of the frequency or time period.
What does the bike run rolling thunder to Washington mean?
"Bike run rolling thunder to Washington" typically refers to the annual Rolling Thunder motorcycle ride to honor prisoners of war and service members missing in action. Bikers gather in Washington, D.C., for a procession that raises awareness about the POW/MIA issue and pays tribute to those who served in the military.
Is it safe to swim indoors during a thunderstorm?
It is not safe to swim indoors during a thunderstorm because lightning can strike a building and conduct through the plumbing or electrical systems. It is best to stay out of the water and wait until the storm has passed before resuming swimming activities.
How does an electrical storm affect my car?
An electrical storm can potentially damage your car by causing power surges that can harm the electrical systems, such as the battery, ignition system, and computer. Lightning strikes can also cause direct damage to the vehicle's electrical components or starting a fire if it hits the car directly. It is recommended to park your car in a garage or under a shelter during electrical storms to minimize any risk of damage.
Is not part of the recipe for a thunder storm to form?
Thunderstorms form when warm, moist air rises rapidly in an unstable atmosphere, leading to the development of cumulonimbus clouds that produce lightning, thunder, heavy rain, and sometimes hail. Key ingredients for a thunderstorm include moisture, instability, lifting mechanism, and a source of heat energy.
Is inside a house safe in a lightning storm?
Being inside a house during a lightning storm is generally safe because the electricity from lightning follows the path of least resistance, such as metal wiring and plumbing, to reach the ground. To further reduce risk, avoid contact with electrical appliances and plumbing during a storm, and stay away from windows and doors.
How old is Cassie Logan in roll of thunder?

Is the speed of sound in air is about 343 meters per second?
Yes, the speed of sound in air at room temperature is approximately 343 meters per second. The exact speed can vary depending on factors like temperature, humidity, and air pressure.
What color is to indicate a storm warning for a boater?
A storm warning for boaters is typically indicated by the color red. This signals that severe weather conditions are expected and that boaters should seek shelter immediately.
What does mount Olympus look like in Percy Jackson?
it's on the 600th floor of the empire stste building. you have to give a golden drachma to get up there. then it's a long walkway through clouds and then the walk way leads to mount Olympus. mount Olympus itself is actually over Manhattan.
If a piano frequency is 256 hz on the right what is the frequency on the other side?
The frequency of a piano note is the same on both sides. If a piano key is producing 256 Hz on the right side, it will also produce 256 Hz on the left side. The frequency is determined by the pitch of the note being played, which is consistent across both sides of the piano.
How often is the Empire State Building struck by lightning each year?
On average, the Empire State Building is struck by lightning about 23 times per year. It is a prominent target for lightning strikes due to its height and location in the New York City skyline.
How could you find the sound frequency to break a glass?
High frequency sound waves can shatter glass if powerful enough. This happens because the glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
Can Anikan use force lightning?
If you're referring to young Anakin, no.
Teen Anakin (Ep. 2 & 3): doubtful, it's not a Jedi technique, so he wouldn't have learned it.
Darth Vader Anakin: No his robotic limbs prevented him from using this force power.
