How do you know if a property is intensive or extensive? Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. Which […]
What determines the period of a pendulum quizlet?
What determines the period of a pendulum quizlet? What determines the period of a pendulum? The length of the pendlum and the acceleration of gravity. The time it takes for a wave to complete one cycle. A long pendulum has a longer period than a shorter pendulum. Where is the most kinetic energy on a […]
What are the main causes of habitat destruction?
What are the main causes of habitat destruction? Habitat destruction is the leading cause of biodiversity loss. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Why do animals die when […]
What is the semi major axis of Earth?
What is the semi major axis of Earth? 1.000 1 What is the value for eccentricity? orbital calculations For a perfectly circular orbit, the eccentricity is 0; with increasing elongation of the orbit’s shape, the eccentricity increases toward a value of 1, the eccentricity of a parabola. What is the eccentricity of a straight line? […]
What is the basic principle of air wedge experiment?
What is the basic principle of air wedge experiment? The phase difference between the two rays is used to get interference fringes. It’s alternative light and dark fringes. The path difference between the rays has to be equal. What is meant by air wedge? Air Wedge. An air wedge is a simple interferometer used to […]
What is the relationship between resistance and current?
What is the relationship between resistance and current? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is the property of […]
What are types of damped oscillation?
What are types of damped oscillation? The diagram shown on the right indicates three types of damped harmonic motion. Critically damped: The system returns to equilibrium as quickly as possible without oscillating. Underdamped: The system oscillates (at reduced frequency compared to the undamped case) with the amplitude gradually decreasing to zero. What is positive damping? […]
Can dogs drink water from a dehumidifier?
Can dogs drink water from a dehumidifier? Would it be safe to use the water I take from my dehumidifier and give it to my pets? No. The typical collection tank from a residential dehumidifier is not a safe source of potable water, and certainly isn’t up to the quality of commercially-distilled water. Is it […]
What is solid to a gas called?
What is solid to a gas called? The solid-to-gas change is called sublimation, while the reverse process is called deposition. Sublimation is isothermal, like the other phase changes. There is a measurable energy change during sublimation; this energy change is called the enthalpy of sublimation, represented as ΔH sub. What are 3 examples of sublimation? […]
Why does black make me look thinner?
Why does black make me look thinner? This illusion could explain why we think black is more flattering than white; black shapes appear thinner than white shapes, possibly because the contours of black objects have more definition. A lighter color object will have lines, shapes, and perhaps partitions on it that are very visible to […]
