Which among these is the main property of insulating material? The insulating material should have the following properties. The material must have high mechanical strength so that it carries the tension and weight of the conductors. They must have high dielectric strength. The material is highly resistive for preventing the flow of leakage current from […]
What happens to the weight of an object when it is taken from Earth to Moon Why?
What is latent heat and its types?
What is latent heat and its types? Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling). What is Latent Heat explain with example? Latent heat, energy absorbed or […]
What kind of reaction is lead ii nitrate and potassium iodide?
What kind of reaction is lead ii nitrate and potassium iodide? precipitation reaction What is the balanced equation for the reaction of lead ii nitrate and potassium iodide? S135: Chemical Rxns – Precipitation – Pb(NO3)2 + KI → PbI2(s) When lead nitrate and potassium iodide are mixed together? Lead nitrate solution contains particles (called ions) […]
What are the three types of intermodal tanks?
What are the three types of intermodal tanks? Types of Intermodal Containers Dry Freight. The dry freight container is the most common type of shipping container. Flat Rack. Flat rack containers are different from many other shipping containers in that they do not have walls and are not enclosed. Insulated. Refrigerated. Open Top. Custom. What […]
What does a hollow point do to a body?
What does a hollow point do to a body? But what does this have to do with hollow points? Well, it’s simple. Since a hollow-point bullet expands when it enters soft tissue, it creates a larger wound channel inside the target, increasing the chances that incapacitating damage will be done. Can you survive a hollow […]
What are the four properties of water?
What are the four properties of water? The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. What are physical and chemical properties of water? We have seen the physical and chemical properties of water and understood its […]
Which physical quantity among the following remains on change when sound wave is reflected from a plane surface?
Which physical quantity among the following remains on change when sound wave is reflected from a plane surface? frequency Which is the following is the requirement for regular reflection of sound? Sound must come back to the person after 0.1 second. For above condition, the reflecting surface must be at a minimum distance of 17.2m. […]
Which gas is the main cause of greenhouse effect?
Which gas is the main cause of greenhouse effect? Carbon Dioxide Why oxygen is not a greenhouse gas? Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. These are symmetric molecules, made of two identical […]
Which state of water has the lowest density?
Which state of water has the lowest density? When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. What type […]
