Question
Convert the following hexadecimal numbers to decimal: middot 0x342a __________ 0x7b94 ______ 0x15d0 __________ The "0x" before each number simply indicates that it is hexadecimal Suppose a 79 liter tank is being filled at the rate of 2.5 liters per minute. How many minutes does it take to fill the tank? Answer to the nearest 0.1 minute. ___________ A new planet has been found orbiting Proxima Centauri. The planet is approximately 4e13 kilometers from the earth. If we send a message to this planet, and the message travels at 3e08 meters per second, how many years would we have to wait for the quickest possible response? Assume the reply, from Proxima Centauri to the earth, also travels at 3e08 m/s. Assume a year, on average, is 365.25 days. 4e13can also be written 4 * 10**13 or as 4middot*10^13 3e08 can also be written 3* 10**8 or as 3* 10^8 ____________Explanation / Answer
Q1)342 a = 13354
7b94 = 31636
15d0 = 5584
Q2)V = 79 lit
Q = 2.5 lit/min
The time reqited to fill the tank will be:
t = V/Q = 79 lit/2.5 lit/min = 31.6 min
Hence, t = 31.6 min
