WebbGlass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered … WebbThe cup is made from thick plastic with lots of tiny air bubbles in it. He asks the class why the cup is so good at keeping a hot drink warm. Three suggestions are made. It contains air which is a poor thermal conductor. The air is trapped in tiny bubbles so very little convection is possible. The plastic is a poor thermal conductor.

Webb7 aug. 2024 · The strip is welded at the end to a metal bar so that it can be attached to the tool. As a third type, a representative of the aerodynamic shape and thus the approach to the shape of the droplet was chosen. This was achieved by welding a bar Φ20 mm with two metal plates, in the shape of an arrow. The shapes of the spikes are shown in Figure 7.

Webb1 (a) A student uses this apparatus to investigate what happens to a current-carrying conductor in a magnetic field. The student connects the two parallel horizontal metal rails to the positive and negative terminals of a power supply. The metal rod AB rests across the rails and is free to move. Explain what happens to the metal rod AB. WebbDownload our open textbooks in different formats to use them in the way that suits you.

WebbIt is determined by the net amount of charged particles (protons and electrons) in the object. Electricity is a broad term that used to mean a lot of things. Generally it refers to the flow of electrons. Energy is the potential to do work (move) on another object. brian and chris
