A. The brain structures involved in memory

Explanation:

When information-processing theorists use the term hardware, they are often referring to the brain structures involved in memory.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

i believe the answer is true.
