The charge carried by a glass rod rubbed with silk is called a positive charge; a proton is a positive charge, while a positive charge is not necessarily a proton. The charge of a rubber stick rubbed with fur is called a negative charge. Negative charges are generally speaking electrons. The charge carried by amber…
1. The generation of liquid pressure Liquid due to the role of gravity, and thus the bottom of the container has pressure, and gravity has a close relationship with the show. Liquid because there is no fixed shape, can flow, and thus there is also pressure on the side walls of the container. Measurement of…
With a burst of solar activity, the northern Lights were visible as far away as Oklahoma and North Carolina on Thursday night and early Friday morning. The aurora can also be seen in the UK and northern Europe. The Northern Lights were very active in many parts of the United States and Canada on the…
What is inertia? Inertia is defined as the property of an object to remain in its original state of uniform linear motion or at rest. Inertia is an inherent property of all objects, whether they are solids, liquids or gases, and whether they are moving or at rest. All objects have inertia. Inertia represents the…
In life, we often find that when we play with rubber bands in the state of being stretched, our hands are also using force, while the longer we pull the more we feel the strain. This is what we will explain today the interaction of forces – the action and reaction forces. The Concept of…
Why do magnets attract iron Magnets have their special magnetic properties that can produce an extremely strong attraction and cause strong reactions between other metallic substances, and the most common is that magnets attract iron. So why exactly do magnets attract iron? The following is the relevant knowledge about it. 1 Magnetic force propagation Magnetic…
