One end of a nylon rope is tied to a brick wall. The rope is stretched horizontally, passed over a pulley 80 meters away, and weighted with a mass 180.0 kg at the end. Waves on the rope are measured, and found to travel at 150 m/s. What is the mass of the rope between wall and pulley? If the rope is shaken sideways at 24.0 Hz, what is the wavelength of the waves produced?

Mass of the rope m = 6.272 kg

Wavelength is equal to 6.25 m      

Explanation:

Length of pulley L = 180 M

Mass at the end of pulley m = 180 kg

Frequency is given f = 24 Hz

Acceleration due to gravity

Tension

Velocity of wave in the rope v = 150 m/sec

Velocity of wave is given by

Therefore mass of the rope

Wavelength is equal to

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

coil wire, increase current, put iron inside the coil
