Which mode of operations has the property that same plaintext blocks will yield same ciphertext blocks.

The speed of sound in air is dependent upon the air temperature and other factors. The speed of sound increases from 334 m/s to 341 m/s between 8:00am and 11:00am. If a horn produces sound with wavelength 0.75 m at 8:00am, what would it produce at 11:00am, assuming the frequency is unchanged?

A combination of an encryption algorithm and a decryption algorithm is called a key.

A string on a guitar is stretched between two points 30.0 cm apart with a tension of 100 N. The mass/length of the string is 0.00300 kg/m. The velocity of wave propagation on the string is

A 2.00 kg mass is connected to a spring with a spring constant of 6.00 N/m. The displacement is given by the expression x(t) = (12.0 cm) sin(ω t). What is the maximum velocity of the mass?
