Which magnetic property best describes a magnet’s ability to act at a distance?

Which instrument is used to measure air temperature

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
