You are sending waves down a spring. You send a small amplitude wave down the spring. Then you send a large amplitude wave. The large amplitude wave is...
A. slower than the low amplitude wave
B. the same speed as the low amplitude wave
C. faster than the low amplitude wave

Auniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance of 1.60 cm . a proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval of 3.20×10-6 s. 1-find the magnitude of the electric field. use 1.60×10-19c for the magnitude of the charge on an electron and 1.67×10-27kg for the mass of a proton 2-find the speed of the proton when it strikes the negatively charged plate
