What affects the strength of van der Waals forces? Number of Electrons Held by the Atoms/Molecules The greater the number of (instantaneous) dipoles formed, the greater the strength of the Van der Waals force. What are the three types of van der Waals forces? van der Waals forces may be classified into three types: electrostatic, […]
What happens to bimetallic strip when heated?
What happens to bimetallic strip when heated? When this bimetallic strip is heated, the brass expands more than the steel and the strip curves with the brass on the outside. If the strip is cooled, it curves with the steel on the outside. Bimetallic strips are used as switches in thermostats. Why is a bimetallic […]
Will 2 iron bars attract?
What happens when comets collide?
What happens when comets collide? A head-on collision. The comets would most probably disintegrate into smaller pieces. In addition, the large amount of thermal energy produced by the collision may be able to vaporize the ice into gaseous water, and may also produce glass particles from the melting of the rock particles. Is it possible […]
How can we reduce loading effect in ammeter?
How can we reduce loading effect in ammeter? using two resistance to vary the gain. however, the input resistance should less than 1k due to the limitation of the input noise.In my design another resistance should larger than 1000k due to the loading effect. Any buffer should be use between output and the resistance to […]
Does higher mass equal higher inertia?
Does higher mass equal higher inertia? The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass – which is roughly the amount of material present in the object. What’s the difference between […]
What are the types of differentiation?
What are the types of differentiation? There are several different factors that can differentiate a product, however, there are three main categories of product differentiation. Those include horizontal differentiation, vertical differentiation, and mixed differentiation. Is Coca Cola a duopoly? Then the most efficient number of firms is two (duopoly). Firms may compete on price or […]
What are 3 types of graphs used in science?
What are 3 types of graphs used in science? Using Graphs in Science Three commonly used types of graphs are bar graphs, circle graphs, and line graphs. Each type of graph is suitable for showing a different type of data. What are 5 types of graphs? Popular graph types include line graphs, bar graphs, pie […]
What are the factors of good health?
What are the factors of good health? So just what are the most important factors for establishing optimum health. Studies indicate that the following five factors make the biggest difference in overall health and wellness: 1) diet; 2) rest; 3) exercise; 4) posture; and 5) avoiding the use of alcohol, drugs and tobacco. What are […]
Does wavelength change with distance?
Does wavelength change with distance? As light travels away from a galaxy, the Universe is continually expanding, meaning that the distance the light needs to travel is continually increasing as well. As space stretches out underneath a beam of light, its wavelength increases, and its energy decreases. Does frequency increase with distance? The frequency of […]
