Which is older intrusion or extrusion? Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. There, the magma cools and hardens into a mass of igneous rock called an intrusion. An intrusion is always younger than the rock layers around and beneath […]
Why is graphite dangerous?
Why is graphite dangerous? Graphite is a form of pure carbon. It is not edible, but not chemically dangerous. Graphite can be made to be more dangerous than Pb depending on ingenuity. For instance if you powder graphite and force a person to breath the powder until they choke, it is more dangerous that a […]
What is the use of Natrium 24?
What is the use of Natrium 24? Sodium 24 is used as an electrolyte tracer to follow the path sodium takes in a person’s body to see if their uptake levels are within normal ranges, while sodium 22 is used in nuclear medicine imaging for positron emission tomography.

What is the difference between SAR and radar?
What is the difference between SAR and radar? SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars. Additionally, SAR has the property of having larger apertures for more distant objects, allowing consistent spatial resolution over a range of viewing distances. What is the […]

Is normal force a centripetal force?
Is normal force a centripetal force? The normal force and a component of the weight point toward the center of the loop (the component perpendicular to the loop), so they get to be the centripetal force. How is centripetal force calculated? Centripetal force is measured in Newtons and is calculated as the mass (in kg), […]
