At what temperature does the exhaust valve open?
Is Bedrock Real?
Is Bedrock Real? Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. Bedrock can extend hundreds of meters below the surface of the Earth, toward the base of Earth’s crust. The upper boundary of bedrock is called its rockhead. Above the rockhead, bedrock may be overlain with saprolite. Is Bedrock […]
What is the weight formula?
What is the weight formula? The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration. Who gave the […]
Is burning of candle a reversible change?
Is burning of candle a reversible change? When a candle is burned, chemical reactions take place between the wax and oxygen. These chemical reactions release energy in the form of heat and light. These chemical reactions can’t be reversed back. What ways to change the materials? What are some ways of changing solid materials? Physical […]
What are the two main functions of cell wall?
What are the two main functions of cell wall? The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell. Where are cell walls found? A cell wall is a fairly rigid layer surrounding a cell […]
What are three types of models?
What are three types of models? Contemporary scientific practice employs at least three major categories of models: concrete models, mathematical models, and computational models. What is simple model? A Simple Model exists to make the skill set required to build financial models more accessible. The intention is to create simple material and facilitate the learning […]

What year did the Narrows bridge collapse? September 1938 How much does it cost to go over the Tacoma Narrows Bridge? Currently, crossing the bridge in a car or another two-axle vehicle costs $5 with a Good to Go! pass or $6 cash at the tollbooth. How big is the Octopus Under the Narrows Bridge? […]
What is negative resonance?
What is negative resonance? Negative Resonance Effect- Negative resonance effect occurs when the groups withdraw the electrons from other molecules by the process of delocalization. The groups are usually denoted by -R or -M. In this process, the molecular electron density is said to decrease. For example- -NO2, C=O, -COOH, -C≡N. What is difference between […]
