Will the Magellanic clouds collide with the Milky Way? The gas in the Stream, and the Magellanic Clouds themselves, will someday collide with our Milky Way, astronomers say. According to these astronomers: The discovery suggests that [the Magellanic Stream] is about half as far from crashing into the Milky Way as previously thought. Can you […]
What is another name for the autonomic nervous system?
What is another name for the autonomic nervous system? visceral motor system What part of the brain controls autonomic nervous system? The hypothalamus is the key brain site for central control of the autonomic nervous system, and the paraventricular nucleus is the key hypothalamic site for this control. What hormone stimulates the parasympathetic nervous system? […]
What is the main difference between vascular?
What is the main difference between vascular? Comparison Chart Basis for Comparison Vascular Plants Roots Vascular plants have a proper root system, which supports the plants to anchor the soil and gets nutrients from it. Leaves Leaves have well defined shape and play role in photosynthesis. Stomata works in gas exchange. Which plant is a […]
Is there more resistance or less resistance at higher temperatures?
Is there more resistance or less resistance at higher temperatures? The more these atoms and molecules bounce around, the harder it is for the electrons to get by. Thus, resistance generally increases with temperature. In some materials (like silicon) the temperature coefficient of resistivity is negative, meaning the resistance goes down as temperature increases. Is […]
What is biological development of a child?
What is biological development of a child? Biological factors can play a particularly important role in early development. These factors influence a child in both positive and negative ways. Biological factors include genetic influences, brain chemistry, hormone levels, nutrition, and gender. What are the key concepts of child development? Cognition – the ability to learn […]
How can you tell if it is a metamorphic rock?
How can you tell if it is a metamorphic rock? Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands. Examples of metamorphic rocks are marble, schist, gneiss, […]
How does temperature affect the motion in liquids?
How does temperature affect the motion in liquids? In liquids, particles are quite close together and move with random motion throughout the container. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. What is the effect of high temperature […]
What is the critical angle for a material of refractive index 2 √ 3?
What is the critical angle for a material of refractive index 2 √ 3? Hence, critical angle for the material is 45°. What is the critical angle for the material of refractive index √ 3? So, the value of critical angle is 35.26 degrees. Hence, this is the required solution. Which among the following has […]
What is the formula for magnetic field?
What is the formula for magnetic field? The Biot-Savart Law can be used to determine the magnetic field strength from a current segment. For the simple case of an infinite straight current-carrying wire it is reduced to the form B=μ0I2πr B = μ 0 I 2 π r . What are characteristics of magnetic field […]
What is the emf of a cell equal to?
What is the emf of a cell equal to? Electromotive force (EMF) is equal to the terminal potential difference when no current flows. EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each […]
