Which subatomic particle has a positive charge and negative charge? The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge. How does […]
What are the disadvantages of living on a floodplain?
What are the disadvantages of living on a floodplain? Disadvantages No buildings or roads will be built in a floodplain area, so it restricts development. High risk of flooding. Why is it bad to build on a floodplain? Building on the floodplains makes the habitats for many creatures rare and unnatural as their natural habitat […]
What is protraction and retraction of shoulder?
What is protraction and retraction of shoulder? Protraction of the scapula occurs when the shoulder is moved forward, as when pushing against something or throwing a ball. Retraction is the opposite motion, with the scapula being pulled posteriorly and medially, toward the vertebral column. What causes protracted scapula? Scapular dyskinesis in impingement is characterized by […]

What is gravitational equilibrium?
What is gravitational equilibrium? Hydrostatic equilibrium, also known as gravitational equilibrium, describes a balance between gravity and pressure. Gravity works to contract while pressure works to expand. Hydrostatic equilibrium is the state where the force of gravity pulling inward is balanced by pressure pushing outward. What is heating the corona? The coronal heating problem in […]
Can Insulators be charged by contact?
Can Insulators be charged by contact? 3 Answers. When you charge an insulator by friction, the close contact of two electron clouds (each from a different medium) allows for electrons to be transferred between them. The number of atoms coming in contact to each other by friction is proportional to the area of the two […]
What is the hardest metal to drill through?
What is the hardest metal to drill through? Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials. […]
What are the characteristics of inelastic collision?
What are the characteristics of inelastic collision? An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else. What do u mean by perfectly […]
What is metal ductility?
What is metal ductility? Material properties Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how ‘soft’ or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present. Is all metals are ductile? Answer […]
Can I charge a 19V laptop with a 12V charger?
Can I charge a 19V laptop with a 12V charger? NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. So your fully charged state is about 13.8 – 14.5V. Putting two batteries in parallel does not change the voltage required to charge them it simply increases the current capability […]
