Answer:
1. Answer: Light can travel in a vacuum, and its speed is constant if the source is moving or stationary.
Light travels at constant speed in vacuum even if the source is moving or stationary. If the source is moving, the apparent frequency/ wavelength changes.
A Trombe wall (Trombe rhymes with prom, by the way) is a wall that warms trapped air, and then circulates it to help heat a house. Trombe walls are ideally made out of a material with a fairly high thermal mass materials (like bricks or concrete), and are often painted black to improve heat conduction

Explanation:
Conductive hearing loss occurs from either (1) blockage from the external ear or (2) damage to any components of the middle ear; hence the answer here is false. Hearing loss that results from damage to the inner ear or the vestibulocochlear nerve is called <em>sensorineural hearing loss</em>.
<em>The most common cause of sensorineural hearing loss is noise-induced hearing loss due to prolonged exposure to high decibel environments (i.e. machine workers). </em>
