What part of the body is least sensitive? trunk Are women’s bodies more sensitive? According to a report published in October’s Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS), women have more nerve receptors, which cause them to feel pain more intensely than men. Who is more […]
Is copper a solenoid?
Is copper a solenoid? An electromagnet is a coil of wire with an electric current flowing through it. When the wire is coiled around in a cylinder, we call this a solenoid. Copper is used because it has a low electrical resistance (see conducting properties). This means that it is easy for the current to […]
What are the 5 parts of the brain and their functions?
What are the 5 parts of the brain and their functions? The Biggest Part: the Cerebrum. The biggest part of the brain is the cerebrum. The Cerebellum’s Balancing Act. Next up is the cerebellum. Brain Stem Keeps You Breathing — and More. Pituitary Gland Controls Growth. Hypothalamus Controls Temperature. You Have Some Nerve! Emotion Location. […]
What are the similarities of mass and volume?
What are the similarities of mass and volume? Mass and volume are two units used to measure objects. Mass is the amount of matter an object contains, while volume is how much space it takes up. Example: A bowling ball and a basketball are about the same volume as each other, but the bowling ball […]
Which electromagnet would be the strongest?
Which electromagnet would be the strongest? Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas, as of 2011. What is a good replacement for copper? Applications where copper will continue to be substituted include cables, plumbing tubes and telecommunications, where aluminum, plastic and fibre optics, respectively, […]
Why is a positive ion smaller than an atom?
Why is a positive ion smaller than an atom? When an atom has its electrons attracted to another atom it becomes a positive ion. The positive ion is smaller than the original atom. This means that with fewer electrons but the same number of positive protons, the size of the ionic radius will decrease. Why […]
Why pitchers should not run?
Why the optical mirrors are mounted externally from laser tube?
Why the optical mirrors are mounted externally from laser tube? A laser tube is mounted on an optical bench so that one of its end mirrors is mounted externally to the tube on an optical bench sliding holder. Careful alignment of the external mirror starts the lasing action, as long as the open part of […]
Which is an example of abiotic factor?
Which is an example of abiotic factor? An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem. […]
Is current Lorentz invariant?
Is current Lorentz invariant? In particular, the charge carried by a particle does not vary with the particle’s velocity. is called the proper density, and is obviously Lorentz invariant. is the current density 3-vector. Clearly, charge density and current density transform as the time-like and space-like components of the same 4-vector. What is the difference […]
