Other examples of transverse waves include light waves and water waves. Both types of seismic wave can be detected near the earthquake centre but only P-waves can be detected on the other side of the Earth. This is because P-waves can travel through solids and liquids whereas S-waves can only travel through solids. This means the liquid part of the core blocks the passage of S-waves.
Have your vehicle's exhaust system inspected periodically to keep your car safe. Loose, missing or damaged hangers or brackets can allow the exhaust system to shift around, causing a possible clunking or rubbing sound while driving. A loose exhaust system, when hot, can also melt wiring, nylon lines or rubber hoses.

Many people overlook this as the cause of engine misfires, because the blown head gasket does not also give the other more common symptoms.When the head gasket fails between a cylinder and the coolant port, coolant may leak into the cylinder.ngine misfire caused by a head gasket. A head gasket that fails between cylinders will generally cause a misfire and perhaps few other symptoms. With a failure between cylinders, compression from one cylinder leaks into another. Lowered compression results in a rough idling engine.
