How many independent variables should an investigation have? one independent variable What’s the dependent variable in science? The dependent variable is the variable that is being measured or tested in an experiment. […]
Who is known as the father of modern astronautics?
Who is known as the father of modern astronautics? For his ideas, careful research, and great vision, Tsiolkovsky has been called the Father of Modern Astronautics. Early in the 20th century, an American, Robert H. Goddard (1882-1945), conducted a variety of practical experiments in rocketry. When did Russia put a man in space? A Is […]
What is the function of sodium ion in human body?
What is the function of sodium ion in human body? Sodium is both an electrolyte and mineral. It helps keep the water (the amount of fluid inside and outside the body’s cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work. Most of the sodium in the body […]
Which is better if the discharge time of the capacitor is small or large?
Which is better if the discharge time of the capacitor is small or large? At first the current is large because the voltage is large, so charge is lost quickly and the voltage decreases rapidly. As charge is lost the voltage is reduced making the current smaller so the rate of discharging becomes progressively slower….Discharging […]
When 20.0 g of a substance are completely melted?
When 20.0 g of a substance are completely melted? When 20.0 grams of a substance is completely melted at its melting point, 820 Joules are absorbed. When a liquid is vaporized how much energy is gained? 20% Is heat released during evaporation? In the case of evaporation, the energy is absorbed by the substance, whereas […]
What is the minimum energy of harmonic oscillator?
What is the minimum energy of harmonic oscillator? Classically, the lowest energy available to an oscillator is zero, which means the momentum also is zero, and the oscillator is not moving. Compare the quantum mechanical harmonic oscillator to the classical harmonic oscillator at v=1 and v=50. On what factor does the angular frequency of simple […]
What are the 3 factors that impact natural selection?
What are the 3 factors that impact natural selection? Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited […]
Is there a relationship between speed and acceleration?
Is there a relationship between speed and acceleration? Speed is the distance covered in a unit of time while acceleration is the rate of change of speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity […]
Which best describes effects of hurricanes?
Which best describes effects of hurricanes? Hurricanes also cause flooding and occur over a broader area. Which best describes the effects of hurricanes? Hurricanes have storm surges that cause widespread flooding. Why Deforestation increases the risk of floods in an area? Deforestation plays several roles in the flooding equation because trees prevent sediment runoff and […]
