Does displacement have direction? Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position. What is final displacement? Displacement is the change in an object’s position from the origin. Her final position Xf […]
What are three interpretations of the coefficients in a balanced chemical equation?
What are three interpretations of the coefficients in a balanced chemical equation? First: the coefficients give the number of molecules (or atoms) involved in the reaction. In the example reaction, two molecules of hydrogen react with one molecule of oxygen and produce two molecules of water. Second: the coefficients give the number of moles of […]
Which component of projectile is constant?
Which component of projectile is constant? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its […]
What happens when a neutral object is grounded?
What happens when a neutral object is grounded? AS the negatively chgarges object approaches the neutral grounded conductor, the electrons in the negative object repel the electrons in the neutral object. Electrons will start to move out of the neutral object and travel to earth/ground as the charged object approaches and before it makes contact. […]
What are three ways to find the volume of an object?
What are three ways to find the volume of an object? Different Ways to Find Volume Solve for Volume by Space. All physical objects occupy space, and you can find the volume for some of them by measuring their physical dimensions. Solve for Volume by Density and Mass. Density is defined as an object’s mass […]
What are the four pillars to the information processing theory?
What are the four pillars to the information processing theory? 1) thinking 2) analysis of stimuli 3) strategization 4) sensory registration 5) situational modification 6) obstacle evaluation 7) generalization. What are the 4 types of processing? This lesson introduces students to four common types of processing: if/then (conditionals), finding a match (searching), counting, and comparing. […]
Does fetus get nutrients before Mother?
Does fetus get nutrients before Mother? The unborn baby is connected to the placenta by the umbilical cord. All the necessary nutrition, oxygen, and life support from the mother’s blood goes through the placenta and to the baby through blood vessels in the umbilical cord. How does the placenta exchange nutrients? Abstract. The exchange of […]
What are three common features of quantitative research?
What are three common features of quantitative research? Its main characteristics are: The data is usually gathered using structured research instruments. The results are based on larger sample sizes that are representative of the population. The research study can usually be replicated or repeated, given its high reliability. What are the key features of the […]
What happens to amplitude when intensity is halved?
What happens to amplitude when intensity is halved? If the amplitude is halved, the new amplitude is and the new power is proportional to . We conclude that when the amplitude is halved, power reduces by 75%. Does frequency decrease with distance? The frequency of sound doesn’t decrease with distance, but it does derease with […]
How do you find current in a RLC circuit?
How do you find current in a RLC circuit? Series RLC Circuit i(t) = Imax sin(ωt) The instantaneous voltage across a pure resistor, VR is “in-phase” with current. The instantaneous voltage across a pure inductor, VL “leads” the current by 90. The instantaneous voltage across a pure capacitor, VC “lags” the current by 90. How […]
