What else can I help you with?
Does eyesight have speed?
Yes. Light has a speed, electric impulses from the retina to the brain have speeds and the neurons in the brain have speeds.
Why does mass increase time dilation and length contraction occur at normal speed 100 mph explain?
Mass does not directly cause time dilation and length contraction; rather, these effects arise from the principles of Einstein's theory of relativity, particularly as objects approach the speed of light. At normal speeds, like 100 mph, the effects are negligible and not perceptible, as they become significant only as an object's velocity approaches a substantial fraction of the speed of light. Time dilation means that time passes more slowly for objects in motion relative to a stationary observer, while length contraction means that an object's length appears shorter in the direction of motion from the perspective of a stationary observer. However, at everyday speeds, the differences are so minimal that they are effectively unnoticeable.
If a train were to move with the speed of light what would be its length?
According to Einstein's theory of relativity, an object cannot travel at the speed of light due to infinite energy required. Therefore, the length of a train moving at the speed of light is an undefined concept.
What happens to mass when a spaceship appraoches the speed of light?
If speed approaches the speed of light, the mass of any object will increase. This is not just theory; it is observed on a daily basis. Not with spaceships, of course; the technology is not ready yet - but with subatomic particles in accelerators.
What is the fastest thing on earth besides light and space shuttles?
The fastest thing on Earth besides light and space shuttles is thought to be the tip of a whip, which can reach speeds of over 1,000 mph. Another fast-moving object on Earth is a bullet fired from a firearm, which can travel at speeds exceeding 1,700 mph.
Is length a constant?
No, length is a relative measure. If an object is travelling close to the speed of light it undergoes Lorenz contraction.
What does an object do to light so you can see it?
Reflects all light beams which have the wave length of the color of that object. Each color has a particular wave length in the electromagnetic spectrum.
Two objects one heavy and one light travel at one of two speeds. Which will have the most inertia?
The one with the largest mass
What is the relationship between the size of the shadow and the distance of the object from the light source?
The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.
How can we know that people traveling at or close to the speed of light will not age as fast as someone not traveling at such speeds when we have no means of reaching such speeds?
Einsteins theory of relativity
What has mass volume and density but not length?
An object moving at the speed of light.
How does the length of an object change as its velocity increases?
As an object's velocity increases, its length will not change. Length contraction is a concept in special relativity that refers to the shortening of an object in its direction of motion relative to an observer, but this effect is generally only significant at velocities close to the speed of light.
When viewing an object close to you your lens should be more?
When viewing an object close to you, your lens should be more curved in order to focus the incoming light accurately on your retina at the back of your eye. This change in lens curvature allows you to see nearby objects clearly by adjusting the focal length of the lens.
When the light is close to an object is the shadow small are big?
When the light source is close to the object, the shadow tends to be smaller because the light is more focused and doesn't spread out as much. As the distance between the object and the light source increases, the shadow becomes larger because the light rays spread out more, creating a bigger shadow.
Object traveling through the speed of light?
Electrons are able to travel close to speed of light.
How are length time and mass altered according to special relativity?
According to special relativity, length contracts in the direction of motion, time dilates (slows down), and mass increases for objects moving at high speeds relative to an observer. These effects become significant as an object approaches the speed of light.
What is a practical example of gravity acting on a moving object?
A car speeds up as a traffic light turns green.
