Surface waves. Seismic surface waves travel along the Earth's surface. They can be classified as a form of mechanical surface waves. They are called surface waves, as they diminish as they get further from the surface. They travel more slowly than seismic body waves (P and S).
Percocet can be detected in the urine for 3-4 days. A blood test can identify Percocet for up to 24 hours. A saliva test can detect Percocet for up to 1-4 days. Percocet, like like many other drugs, can be detected with a hair follicle drug test for up to 90 days.
How long does Percocet stay in your system? About 3 days (72 hours) if you've only taken one or two doses on the same day. But it largely depends on how much you've taken and how long you've taken it. If you've taken it â¦ for a while, or taken large doses of it, then it will be in your system longer.
