What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?
OLEGan [10]
This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.

An ocean wave has a wavelength of 10 m and a frequency of 4.0 Hz. What is the velocity of the
aleksandr82 [10.1K]

The velocity of the wave is 40 m/s

Explanation:

The relationship between the velocity of a wave and its frequency and wavelength is given by

v=f \lambda

where

v is the velocity

f is the frequency

\lambda is the wavelength

For the ocean wave in this problem, we have:

\lambda = 10 m (wavelength)

f = 4.0 Hz (frequency)

Therefore, its velocity is

v=(4.0)(10)=40 m/s
