How much less energy does a magnitude 4 earthquake have than a magnitude 7?
Each increase by one magnitude corresponds to a release of energy 31.6 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has roughly 1/31554th the energy of the magnitude 7.Each increase by one magnitude corresponds to a release of shaking amplitude 10 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has 1/1000th the shaking amplitude of the magnitude 7.The amount of energy changes much more rapidly with magnitude than the amount of shaking amplitude. This is a commonly made error.
What is the difference between a twelfth magnitude and fifteenth magnitude star?
The main difference is brightness: a twelfth magnitude star is brighter than a fifteenth magnitude star. Magnitude is a logarithmic scale, so each step in magnitude represents a difference in brightness of about 2.5 times. This means a twelfth magnitude star is approximately 12.5 times brighter than a fifteenth magnitude star.
What is the absolute magnitude of this star m equals 6?
The absolute magnitude of a star is a measure of its true brightness if it were placed at a standard distance of 10 parsecs from Earth. To calculate the absolute magnitude from the apparent magnitude (m) of 6, you would need to know the star's distance. Without this information, we cannot determine the absolute magnitude.
The light from Sirius is 24.2 times more intense than light from Polaris What is the magnitude difference?
The magnitude difference between two stars can be calculated using the formula: Magnitude difference = 2.5 * log10(Intensity1 / Intensity2). In this case, the magnitude difference between Sirius and Polaris would be 2.5 * log10(24.2) ≈ 1.94.
The Greeks assigned what magnitude to the brightest stars seen in the night sky?
The brightest stars were traditionally magnitude 1; the weakest that could still be seen with the naked eye, 6. This system has been formalized and refined; as a result, there are now not only magnitudes with decimals, but also negative magnitudes for the very brightest stars and planets. For example, Venus has a magnitude of approximately minus 4.
What is a unit vector?
It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.
Star A is a first magnitude star. Star B is a sixth magnitude star. Which star is brighter and by how much?
A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.
How the magnitude of vector is equal to 1?
If the sum of the squares of the vector's components is ' 1 ',then the vector's magnitude is ' 1 '.
What magnitude is not possible when a vector of a magnitude of 3 is added to a vector of a magnitude of 4?
It is not possible to obtain a vector with a magnitude of 7 when adding vectors of magnitude 3 and 4. The resultant magnitude will be between 1 and 7, as the triangle inequality states that the magnitude of the sum of two vectors is less than or equal to the sum of their magnitudes.
What magnitude is not possible when a vector of magnitude 3 is added to a vector of magnitude 4?
7
What is the magnitude weakest possible earthquake recorded?
it might be 1 magnitude.
What is the order of magnitude of 15?
The order of magnitude for 15 is 1. -Apex.
Which is what star would be the brightest magnitude 1st 2nd 3rd?
A star with a magnitude of 1 is the brightest, followed by a magnitude of 2 and then a magnitude of 3. The lower the magnitude, the brighter the star appears in the sky.
What happens to the size of a number when you find the square or the square root of it?
The answer depends on the size of the number that you start with. Squares:x < -1: x2ispositive, magnitude larger than |x|x = -1: x2=1-1 < x < 0: x2ispositive, magnitude smaller than |x|x = 0: x2=00 < x < 1: x2ispositive, magnitude smaller than xx = 1: x2=1x > 1: x2ispositive, magnitude larger than x.Square Roots (except for x = 0, there are two roots)x < -1:√x are imaginary, magnitude smaller than |x|x = -1 :√x =±i, magnitude = 1-1 < x < 0:√x are imaginary, magnitude larger than |x|x = 0:√x = 00 < x < 1:√xare real, magnitude larger than xx = 1:√x=±1x > 1:√xare real, magnitude smaller than x.
