What kind of element has high ionization energy? The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest. Which elements require the most energy to remove a valence electron? Answer Expert […]
What are the 4 types of touch receptors?
What are the 4 types of touch receptors? The four major types of tactile mechanoreceptors include: Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscles. Merkel’s disk are slow-adapting, unencapsulated nerve endings that respond to light touch; they are present in the upper layers of skin that has hair or is glabrous. What are the […]
Why do we need to change used fuse?
Why do we need to change used fuse? Safety. Overcurrent protective devices that have tripped are often reset without first investigating the cause of the fault. When a fuse opens it is replaced with a new fuse, so the protection level is not degraded by previous faults. Our current limiting fuses meet the UL and […]
What are the four elements of sound?
What are the four elements of sound? Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration, or in musical terms, pitch, dynamic, timbre (tone color), and duration. […]
What type of waves can the human eye detect?
What type of waves can the human eye detect? The human eye can detect the visible spectrum of the electromagnetic spectrum — a range of wavelengths between 390 to 700 nanometers. This is why scientists have always assumed that infrared light, a type of electromagnetic radiation with longer wavelengths than visible light, has been “invisible” […]
What are the 2 conditions necessary for the conduction of heat?
What are the 2 conditions necessary for the conduction of heat? (i) The two objects should be in direct contact with each other. (ii) The temperature of the two objects should be different. Heat will flow from a hotter object to a cooler object. What phenomena describe when a huge rock at the state park […]
What is a simple definition of motion?
What is a simple definition of motion? In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. Thus, everything in the universe can be considered to be in motion. What is distance in science definition? Distance […]
Which lines must be parallel?
Which lines must be parallel? If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel. Which line is a transversal? Definition: A line that cuts across two or more (usually parallel) lines. In the figure below, the line AB is a transversal. It cuts across the parallel […]
What are the 3 zones of estuary?
What are the 3 zones of estuary? Coastal habitats can vary depending on geographic region. The three main types of estuary habitats include salt marshes, seagrass, and mangroves. What are the three zones of an estuary? The first zone is where the river begins to meet the saltwater. It has more fresh water than saltwater. […]
Is Kryptonite a Krypton?
Is Kryptonite a Krypton? Despite its name, Kryptonite is not made of the element Krypton. There are a number of versions of Kryptonite over the seven decades Superman has existed, but no matter when it is described, it is almost never composed entirely of the noble gas, Krypton. Can Kryptonite kill Batman? Exposure to kryptonite […]
