What is the scientific process of inquiry? It usually consists of six steps: question, observation or investigation, hypothesis, experiment, analysis of data (reviewing what happened during the experiment), and conclusion. Scientific inquiry, on the other hand, is non-linear, which means it does not follow a consistent step-by-step process. Which of the following is the correct […]
Which factors influence the velocity and duration of muscle contraction?
Which factors influence the velocity and duration of muscle contraction? Force, Velocity, Exercise, and Smooth Muscle The # of muscle fibers stimulated (more more units stimulated = greater contraction) The size of muscle fibers stimulated (bulkier muscles = greater tension = greater force) Frequency of Stimulus (rapid stimulus = greater contraction) Degree of muscle stretch […]
Does resistor drain battery?
Does resistor drain battery? If the resistor value is high the current will be lower therefore draining the battery slower. But at the same time a high value resistor will have a high voltage drop. As the battery voltage drops this voltage drop across the resistor will prohibit the LED from emitting light before the […]
Why does friction cause a skater to slow down and eventually stop?
Why does friction cause a skater to slow down and eventually stop? The force of friction opposes the motion of the rolling skateboard and would eventually bring it to a stop without any help from Lauren. Friction opposes the motion of all moving objects, so—like the skateboard—all moving objects eventually stop moving even if no […]
How long is a sidereal day?
How does digestive system work with muscular system?
How does digestive system work with muscular system? Digestion The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion called […]
What are 2 factors that affect the friction force between 2 objects?
What are 2 factors that affect the friction force between 2 objects? The factors that affect the friction between two surfaces are the weight of the object and the coefficient of friction of the surface. Why friction is directly proportional to normal force? Friction is proportional to the force with which an object pushes against […]
What are the two types of mechanical waves?
What are the two types of mechanical waves? Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. Which of […]
What is an upwell?
What is an upwell? intransitive verb. : to well up specifically : to move or flow upward. How does downwelling occur? Downwelling occurs when the water on the surface of the sea becomes denser than the water beneath it and so it sinks. Most downwelling happens at the poles. There, cold air chills the water. […]
What will be the density of lead under a pressure of 2 * 10 8?
What will be the density of lead under a pressure of 2 * 10 8? 14g/cm3. What happens to pressure when temperature increases and volume increases? Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a […]
