Question 1

The equation 
Is the same as
A) 
B) 
C) 
D) 
E)

Accepted Answer

The only difference between the given equation and option B is in the 5th digit of the second group. In the given equation it is "e", whereas in option B it is "0d". Based on hexadecimal values, the decimal equivalent of "e" is 14 and the decimal equivalent of "0d" is 13. Therefore, the value in the 5th digit has changed by a unit of 1. Since the remaining digits of the equation and option B are the same, this is the correct choice.

Question 2

Bats can detect small objects such as insects that are of a size approximately that of one wavelength.If bats emit a chirp at a frequency of 60 kHz,and the speed of sound in air is 340 m/s,what is the smallest size insect they can detect?
