Hello,
Would you mind confirming my answers are correct please?
(I added the maths but are not needed, just my answers).
Thank you
How many times greater is the maximum ground motion of a magnitude 7 earthquake compared with that of a magnitude 3 earthquake? Enter your answer as a simple number in the box provided. Do not use scientific notation. 10000 It's 4 points more: 10x10x 10 x 10 =10 000 or =10* =10 000 (in simple numbers) A magnitude 7 earthquake is 10,000 times greater than a magnitude 3 earthquake. Express the quantity 5 " in SI base units, using scientific notation combined with negative power notation. (Negative power notation is notation of the type which expresses + as 2 7, and as Jm . ) X2 5 min = 5 x 10-3 m S S = 1 mm = 10-3 m SO, 5 mm = 5 x 10-3 m S S Therefore, the quantity mm = 5 S in SI units, using scientific notation combined with negative power notation is: = 5 x 10-3 m SIn the equation b = the SI units of the quantity a are kg m3 s-2, the SI units of the quantity e are kg and the SI units of the quantity d are m s-2. What are the correct SI units for the quantity b? X2 The SI units of b = bm2 So, adding to the equation: b = kgm35-2 kg x ms-2 Simplifying b: = v(m?) The SI units of b is meter (m) since the square root of m is m. Therefore, b has a unit of meter. bm2 a kgm3s-2 Vekgxams-2 = bm2Rearrange the equation e = to make a the subject.
