When a mass m hangs from a vertical wire of length l, waves travel on this wire with a speed v. if you could explain how you got the answers and the logic that would be awesome and i'll award you the points! you! a. what will be the speed of these waves if we triple m without stretching the wire? b. what will be the speed of these waves if we replace the wire with an identical one, except twice as long? c. what will be the speed of these waves if we replace the wire with one of the same length, but two times as heavyd. what will be the speed of these waves if we stretch the wire to thrice its original lengthe. what will be the speed of these waves (in terms of v) if we increase m by a factor of 18.0, which stretches the wire to double its origina length?

Acar accelerates from 5.0 m/s to to 11 m/s at a rate of 3.0 m/s^2. how far does it travel while accelerating? 20m 117m 43m 16m

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
