How many second does it take for sun's light to reach the

A: The speed of light is approximately 1,079,000,000 kilometers/hour (670,600,000 miles/hour). On average, the Sun is 150 million kilometers (93 million miles) away from Earth. This means that it takes a photon of light about 8 minutes and 20 seconds to travel from the Sun to Earth First of all, the Earth orbit the Sun at a distance of about 150 million kilometers or 1.5*10^11 meters. The speed of light is about 3*10^8 m/s. In order to answer a question, we will use the following equation: t = d/v, where d - distance in meters, v - speed in meters per second and t - time in seconds. t = 1.5*10^11 / 3*10^8 = 500 se

How long does it take for sunlight to reach the earth

Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface If we plug that into the equation 1/d^2 = 1/2^2 = 1/4 = 25% The spacecraft is getting only one quarter of the amount of sunlight that would reach it if it were near Earth. This is because the light is being radiated from the Sun in a sphere. As the distance from the Sun increases the surface area of the sphere grows by the square of the distance At the speed of light, a photon will take about 8.3 minutes (500 seconds) to reach Earth. For sunlight to reach the Earth's Surface is about 8 minutes and 20 seconds

PLEASE HELP!!! algebra. The speed of light is approximately 3.0 x 10^8 meters per second. The speed of sound is approximately 3.4 x 10^2 meters per second And to illustrate the fact, James O'Donoghue, a Nasa scientist based at the Goddard Space Flight Center in Maryland, USA, created this brilliantly simple video that shows how long it takes light - originating from the sun - to reach the planets in our solar system. It takes about 8 minutes for light to reach Earth and over FIVE hours for the same light beam to reach Pluto, the farthest. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface. Learning Lesson: Canned Heat However, since the Earth is much cooler than the Sun, its radiating energy is much weaker (long wavelength) infrared energy Instead, the sun radiates much of its energy as light of various wavelengths. Some of this radiated light is in the infrared part of the spectrum and reaches Earth as heat. Light in the visible part of the spectrum also has the effect of warming the Earth. It does this by penetrating the atmosphere and being absorbed by the land and water For 1AU light takes about 8.3 minutes/. So multiply and get answers. 10.686x8.3=88.6 minutes 9.02x8.3=74.86 minutes

The sun is 93,000,000 miles from the Earth. The speed of light is 186,000 miles per second. How long does it take a ray of light to reach the Earth? The correct answer is 8 minutes, 20 seconds. For this lab assignment, complete the following: 1. Open a command window (or DosBox), start DEBUG, and enter these commands: a mov dx,1 mov ax,6b48 mov. The core of the Sun has so much pressure that nuclear fusion occurs. That energy eventually gets to the surface of the sun and shows up as light. The sunlight we see is about 6000 Kelvin or 10340.33° Fahrenheit. A longer explanation of the sun's nuclear fusion process can be found at the University of California - San Diego's Calspace. How long does it take for moonlight to reach the earth? Asked by: Cara Answer Light travels through space at just over 186,000 miles per second. The moon is just under 250,000 miles from Earth, so light from the Moon's surface has to travel more than one second (about 1.3 seconds) to reach us The Sun is the largest object within our solar system, comprising 99.8% of the system's mass. The Sun is located at the center of our solar system, and Earth orbits 93 million miles away from it. Though massive, the Sun still isn't as large as other types of stars. It's classified as a yellow dwarf star

Solving the problem numerically, Klotz found that an object should fall through Earth in 38 minutes and 11 seconds, instead of the 42 minutes and 12 seconds predicted assuming a uniform planet It is here that the sunlight and heat that are radiated and convected to the surface propagate out into space. Temperatures in the layer range between 4,500 and 6,000 K (4,230 - 5,730 °C; 7646. Even the light from the sun takes around 8 minutes to reach the earth which means if, let's say, the sun vanishes we won't know it until next 8 minutes. Even when we gaze at the night sky we are. The Earth's atmosphere has some capacity to hold in heat but not much of one. A relatively simple calculation would show that the Earth's surface temperature would drop by a factor of two about every two months if the Sun were shut off. The current mean temperature of the Earth's surface is about 300 Kelvin (K)

To do this, put Pluto in the center of your screen and change the unit of measurement above the ruler along the bottom of [ On our sun it'd take about 255 seconds to reach that velocity (presuming a constant gravitational gradient, which it isn't, but good enough for this cheap example) (since v=gt thus t=v/g 255. The sun presents an angular width of 32 arcminutes to any point on earth. That is 32/60 or 0.533 degrees of arc or angular span. Lets assume the Earth does not have its 23 degrees of tilt, for this first approximation. Then as a second approximation lets assume the Earth rotates around the sun in 24 hours, you are still on the equator

Since the Moon orbits the Earth and the Earth orbits the Sun, both the Moon and the Earth are the same average distance away from the Sun. On average, the Earth and Moon are about 150 million kilometres (or 93 million miles) from the Sun! That distance is so large that it takes light eight minutes to reach us (remember that light travels at. It would take 65,000 years for the Earth to move away one kilometer (I can walk that far in a few minutes). Assuming the mass loss is constant, the Earth has only moved out from the Sun 70,000 km. Sun. Star. How many light years does it take to get to the sun? It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years).
