During a rising tide, ocean waves often become larger. if the amplitude of a wave increases by a factor of 1.1, by how much does the energy increase?

1.21 times

Explanation:

The energy of a wave is proportional to the square of the amplitude of the wave.

Mathematically:

where

E is the energy of the wave

A is its amplitude

In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as

Therefore, this means that the energy of the wave increases by a factor:

Therefore, the energy of the wave increases by a factor 1.21.

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.
