Can I leave laptop plugged in all the time?
Can I leave laptop plugged in all the time? But if you’re like most people, you probably keep yours plugged in when you’re at work or home. Stop doing that. In order to squeeze as much life out of your lithium-polymer battery, once your laptop hits 100 percent, unplug it. In fact, you should unplug […]
What are the examples of elastic potential energy?
What are the examples of elastic potential energy? Many objects are designed specifically to store elastic potential energy, for example: The coil spring of a wind-up clock. An archer’s stretched bow. A bent diving board, just before a divers jump. The twisted rubber band which powers a toy airplane. A bouncy ball, compressed at the […]
What are examples of unbalanced force?
What are examples of unbalanced force? Practically anything that moves is a result of the exertion of unbalanced forces on it. If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is […]
Why are nitrogen compounds explosive?
Why are nitrogen compounds explosive? Nitro compounds are explosive because although the diatomic form of nitrogen is very stable – that is, the triple bond that holds N2 together is very strong, and therefore has a great deal of bond energy – the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and […]
Is a higher refractive index better?
Is a higher refractive index better? The higher the refractive index, the closer to the normal direction the light will travel. When passing into a medium with lower refractive index, the light will instead be refracted away from the normal, towards the surface. Which has highest refractive index water or glass? Solution. The refraction index […]
What are the two major somatosensory pathways?
What are the two major somatosensory pathways? The somatosensory system consists of the two main paired pathways that take somatosensory information up to the brain: the medial lemniscal or posterior pathway, and the spinothalamic or anterolateral pathway. The somatosensory pathways are made up of a relay of four neurons. What part of the brain is […]
What gas looks like on ultrasound?
What gas looks like on ultrasound? Gas appears on ultrasound as a bright reflective surface with shadowing that obscures the underlying anatomy, with either long path reverberation artifacts (for large gas collections) or short path ‘ringdown’ artifacts (for small gas collections), although very small locules of gas may not cast an acoustic shadow or … […]
Can amber be made artificially?
Can amber be made artificially? Artificial amber stones can be amazingly beautiful – transparent, sunny, even with some bug or spider inside! And in some cases, it is rather difficult to identify such imitation from a natural mineral. Artificial amber is made from glass, modern types of plastic, as well as synthetic and natural resin. […]
What makes a synovial joint unique?
What makes a synovial joint unique? Synovial joints allow for movement. Where the bones meet to form a synovial joint, the bones’ surfaces are covered with a thin layer of strong, smooth articular cartilage. A very thin layer of slippery, viscous joint fluid, called synovial fluid, separates and lubricates the two cartilage-covered bone surfaces. What […]
