What is a difference between a law and a hypothesis? A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. What is the percent error between the […]

How do you calculate energy requirement?
How do you calculate energy requirement? To calculate the energy required to raise the temperature of any given substance, here’s what you require: The mass of the material, m. The temperature change that occurs, ΔT. The specific heat capacity of the material, c (which you can look up). Here is a source of values of […]
What do you mean by internal forces?
What do you mean by internal forces? Internal forces are forces exchanged by the objects in the system. Internal forces may cause acceleration in different parts of the system but does not cause any acceleration in the center of mass of the entire system. Example: Friction is an external force if the body experiencing friction […]
Does material affect friction?
Does material affect friction? The frictional force does not depend on mass or surface area. All that really matters is the types of materials that are in contact. When everything is stationary, the objects feel static friction. When they are moving, kinetic friction takes over. What 2 factors do not affect friction? Friction does not […]
How do scientists study landslides?
How do scientists study landslides? To be able to predict landslides, scientists have developed slope stability models to analyze the risk locally. More recently, NASA has created a preliminary algorithm to map landslide hazards globally using satellite measurements of rainfall, land cover and other surface variables. What do you think is the best way to […]
What is a mass balance equation?
What is a mass balance equation? Mass-Balance Equations. ➢ Mass-balance equations relate the equilibrium concentrations of various species in a solution to one another and to the analytical concentrations of the various solutes. ➢ These equations are a direct result of the conservation of mass and. moles. What does it mean to tare a balance? […]
How can we protect Earth from solar activity?
How can we protect Earth from solar activity? Earth’s magnetosphere, the first layer of protection against solar flares, whisks away the flare’s charged particles. Due to the effects of the solar wind, the magnetosphere has a compressed, bulbous side that faces the sun, a dip near Earth’s poles and a flowing tail extending away from […]
How many codons are needed to make 4 amino acids?
How many codons are needed to make 4 amino acids? 64 How do the amino acids know where to drop off an amino acid? The bases are read in groups of threes, called codons. Transfer RNA (tRNA) molecules have anticodons (a sequence complementary to the codons). tRNA molecules look for a sequence which complements theirs […]
How does culture influence behavior?
How does culture influence behavior? If culture fosters a more extroverted personality style, we can expect more need for social interaction. Additionally, Individualistic cultures foster more assertive and outspoken behavior. When the general population encourages these gregarious behaviors, more ideas are exchanged and self-esteem increases. How does culture influence cognitive development? Within the context of […]
