Asmall sphere with mass 5.00×10−7 kg and charge +8.00 μc is released from rest a distance of 0.500 m above a large horizontal insulating sheet of charge that has uniform surface charge density σ = +8.00 pc/m2.

using energy methods, calculate the speed of the sphere when it is 0.100 m above the sheet.

Several processes form metal ore. match each process to its description. volcanic activity weathering hydrothermal energy rocks break down as they interact with air and water. arrowright density differences and other factors cause metals to concentrate in igneous rocks. arrowright seawater heats up from contact with hot rock, and metals dissolve in it. the water rises and contacts cooler water, causing metal ores to settle on the ocean floor. arrowright

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.
