What two physics mistakes occur in a science-fiction movie that shows a distant explosion in outer space where you see and hear the explosion at the same time?

OK in outer space , the first thing is sound does not travel in a vacuum also there is no concussion. In films the explosion , and sound happen at the same time, NOT possible, sound travels slower than the light. So if you see an explosion, the sound would arrive later not at the same time, unless u were stood right beside it.

The first mistake is that sound cannot travel through the vacuum of space, so any explosion in outer space would not be audible. The second mistake is that light travels faster than sound, so in reality, you would see the explosion before hearing it if there were sound.

∙ 15y ago# You can't hear an explosion in space, because sound is a vibration and it needs something to carry the vibration, such as a solid, liquid or gas. Space is nothing. It is neither solid, liquid nor gas, hence there is nothing in space to vibrate! In air the sound 'energy' is transmitted by molecules of air 'vibrating' by rapidly bumping into adjacent molecules in an ever-increasing wave of sound, like the ripples of water on a pond after a stone has been thrown in. # You can't hear sound and see light at the same because light and sound travel at different speeds. In air sound travels at about 1/5th of a mile per second, whereas light travels at about 300,000,000 metres (186,282 miles) per second in space and only fractionally slower in air.

Why do scientists study distant galaxies to learn about galaxies?
Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.
Is a volcanic explosion a chemical reaction?
A volcanic explosion is not a chemical reaction in the traditional sense. It is a physical process driven by the release of pressure from magma that has accumulated below the Earth's surface. However, chemical reactions can occur during volcanic eruptions as different elements in the magma interact with each other or with the surrounding rocks.
What is the difference between quantum physics and physics?
Nothing. Quantum is a branch of physics
What does physics stand for or full form of physics abbreviation physics?
The full form of the word physics is physics. It does kind of sound like it derives from the word physical science or physiology or something but it doesn't.
What is the contribution of chemistry in physics?
contribution of chemistry to physics
What two physics mistakes occur when you see and hear a distant explosion at the same time?
The two mistakes are that sound travels slower than light, so if you see and hear a distant explosion at the same time, the explosion actually happened some time earlier. Additionally, the speed of light is much faster than the speed of sound, so the light from the explosion will reach you much sooner than the sound.
What two physics mistakes occur when you see and hear an explosion from outer space in movies?
1.that you see the explosion and hear it at the same time , while you should see first and here it later. 2.that sometimes there is smoke which immposible since there is no air.
How does the physics of an explosion kill you?
An explosion releases a large amount of energy in a short period of time, creating a shockwave that propagates through the air. This shockwave can cause rapid changes in pressure and temperature, leading to severe injuries such as internal bleeding, organ damage, and blunt force trauma. Additionally, the explosion may generate projectiles or flying debris that can cause further harm to individuals in the vicinity.

How does the linear momentum of the satellite before the explosion compare with the total linear momentum of all the pieces after the explosion. The satellite exploded far from any other body in space?
It's the same after explosion. This is because an explosion is an internal force on the satellite. In physics, an internal force on an object does not affect its motion. The center of mass of the object will continue to move as if no explosion occured. Watch a fireworks show, and you can kind of visualize this.

How to solve any physics problem Any?
One should start by following a systematic procedure so as to ensure the avoidance of the trivial mistakes and develop good habits.
Why does the atom bomb make a mushroom shaped cloud?
Any explosion on the ground makes a mushroom cloud, even small grenades. This is because of the physics of the explosion. The high pressure pushes out rapidly, making a low pressure zone in the middle of the explosion. Air rushes back in to fill this area, making the smaller "pinched" area that looks like the mushroom stalk.

What is human error in physics?
Human error in physics refers to mistakes or inaccuracies made by individuals during experiments, measurements, or data analysis. These errors can result from factors such as incorrect technique, misreading instruments, or miscalculations, which can lead to inaccurate data or conclusions. Researchers must be cautious and diligent to minimize human error and ensure the reliability of their results.
