It comes from the sun, and then it is converted to energy/electricity (by solar panels)
less than 20 Hz
The frequency of subsonic sound is less than 20 Hz
subsonic sound refers to a sound which has a wave that travels slower than the speed of sound.
- frequency of audible sound: 20 Hz to 20,000 Hz
<u>Thus </u>subsonic sound < 20 Hz
Answer:
The acceleration that the jet liner that must have is 2.241 meters per square second.
Explanation:
Let suppose that the jet liner accelerates uniformly. From statement we know the initial () and final speeds (), measured in meters per second, of the aircraft and likewise the runway length (), measured in meters. The following kinematic equation is used to calculate the minimum acceleration needed (), measured in meters per square second:
If we know that , and , then the acceleration that the jet must have is:
The acceleration that the jet liner that must have is 2.241 meters per square second.
Answer:
Fold mountains
Explanation:
When plates collide or undergo subduction (that is – ride one over another), the plates tend to buckle and fold, forming mountains. Most of the major continental mountain ranges are associated with thrusting and folding or orogenesis.
