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 does it mean if a girl says Nevermind? “Never mind.” means “I don’t really know how to explain this in a way you’ll understand.” “Nothing.” means “Something, but I’m going to test you to see how you react.” “So, who is she?” means “Okay, I’m trying really hard to not sound jealous, but I’m […]

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 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 […]

Is 19 km/h wind strong? 10 to 19 km/h Weather wanes will move, leaves will rustle, and you’ll feel a breeze on your face. Situation normal. 20 to 29 km/h Strong enough to straighten flying flags and shake small tree branches. How much is 70 km in miles per hour? Convert 70 Kilometers per Hour […]

What are the five changes of state? Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. What are the 22 states of matter? What are the 22 states of matter? Solid. Liquid. Gas. Plasma. Bose-Einstein Condensate. Excitonium. Degenerate Matter. Photonic Matter. What are the 7 types of matter? The seven states of […]

How do you determine instantaneous speed? Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. What does instantaneous rest mean? It […]

What is the relationship between the earth and the moon? The Moon is smaller than the Earth and orbits around the Earth in 27.3 days as the Earth revolves around the Sun. The Moon is held in orbit around the Earth by the force of gravity. In turn the Earth and all the other planets […]

What is the very first step in the proton-proton cycle? The first step in this process is the collision of two protons where proximity permits the strong nuclear force to bind them together. The resulting combination is not stable, and one of the protons will decay to become a neutron, and this forms a stable […]

Is it safe to swim to a sandbar? The trough can be a gentle swim, but the sandbars around it can also shift to create the rip currents — channeled rushes of water pulling away from shore — that have caused so many drownings and near drownings over the years. “You are always going to […]
