Answer: in a medium
Explanation:
Mechanical waves require medium to transfer energy. The medium particles vibrate about their fixed position to transfer energy. There is no transport of medium particles.
Example, sound waves are mechanical waves. The sound travels through compression and rarefaction of the medium particles.
The energy is being converted to the water yet it isn't rising because the water is absorbing the heat not reflecting it. I think this is correct but I'm not sure. I would like to know the answer if you find out though.
Well, first of all, the truck's velocity is constantly changing, not 'uniform'.
Velocity consists of speed and direction. So, even if the truck's speed is
constant, its direction keeps changing as long as it's on a circular curve,
so its velocity is constantly changing.
The force needed to keep a mass moving in a circle is
F = (mass) x (speed)² / (radius)
3300 N = (1600 kg) (13 m/s)² / R
3300 kg-m/s² = (1600 kg) (169 m²/s²) / R
R = (1600 kg) · (169 m²/s²) / (3300 kg·m/s²)
= (1600 · 169 / 3300) meters
= 81.9 meters
Answer: Fibres are very thin, thread-like strands from which fabrics or cloth is made. Examples of fibres are cotton, wool, silk, flax, jute, nylon, polyester, polyacrylic. The fibres are spun into yarn which can then be woven on a Loom to make a fabric or cloth
