Light travels approximately 300,000,000 metres each second. A light year is the total distance travelled by light in one year. Assuming there are 365 days in a year, determine a light year, expressing your answer in Standard Form (and with the correct unit!). 2. The radius of the Earth is 6378.1km. What is the circumference of the Earth in metres, in Standard Form? How many times can light fully encircle the Earth per second? = 7.48 times 3. A ‘bit’ is the smallest unit of space in computing (holding a ‘0’ or ‘1’ value). There are 8 bits in a byte, 210 bytes in a kilobyte, 210 kilobytes in a megabyte, 210 megabytes in a gigabyte and 210 gigabytes in a terabyte. The size of the internet is approximately 5 x 106 terabytes. How many bits are there on the internet (in Standard Form)? Part D Bob the Rubbish Mathematician has failed to put these numbers in Standard Form correctly. Fix them up. Part E Determine the result of these following multiplications and divisions.
