What activates and deactivates the electromagnet?
What activates and deactivates the electromagnet? Electromagnets Can Be Turned On and Off When the electrical current is active, the electromagnet produces a magnetic field. When it’s not active, the electromagnet doesn’t produce a magnetic field. After lifting the load and moving it to a different area, a worker may deactivate the electromagnet to release […]

How do igneous rocks look like?
How do igneous rocks look like? Extrusive, or volcanic, igneous rocks look dull and do not sparkle much because they are fine grained. These crystals make a coarse-grained igneous rock called plutonic, or intrusive, igneous rock because the magma was intruded into cracks deep under the earth’s surface. What type of rock is granite? Granite […]

Is angular momentum conserved rolling without slipping?
Is angular momentum conserved rolling without slipping? In rolling motion without slipping, a static friction force is present between the rolling object and the surface. A rigid rotating body has angular momentum directed along the axis of rotation. 11.4: Conservation of Angular Momentum. In the absence of external torques, a system’s total angular momentum is […]
