Why sea waves are high at night? High tides and low tides are caused by the moon. The moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are […]
What are the two most commonly used domestic circuit?
What are the two most commonly used domestic circuit? 1) The lighting circuit with a 5 A fuse for running low power-rating devices such as electric bulbs, tube-lights, fans, radio, television, etc. 2) The Power circuit with a 15 A fuse for running high power- rating devices such as electric iron, room heater, geysers, refrigerators, […]
What is called vector give one example?
What is called vector give one example? Organisms which do not cause diseases themselves, but spread infection by transferring disease-causing microorganisms from an infected person to others are known as vectors. Eg. Mosquitoes. The diseases causing agents are called vector . Can a human be a vector? But what about humans: Can we humans be […]
Is it meaningful to interpret the Y intercept?
Does the ear canal connected to the brain?
Does the ear canal connected to the brain? The Inner Ear: Nerve Signals Start Here The snail-shaped cochlea changes the vibrations from the middle ear into nerve signals. These signals travel to the brain along the cochlear nerve, also known as the auditory nerve. The semicircular canals look like three tiny connected tubes. What organ […]
How spherical aberration is corrected?
How spherical aberration is corrected? Spherical aberration can be eliminated by making lenses with an aspheric surface. Descartes showed that lenses whose surfaces are well-chosen Cartesian ovals (revolved around the central symmetry axis) can perfectly image light from a point on the axis or from infinity in the direction of the axis. How do you […]
What is the best white balance for indoors?
What is the best white balance for indoors? Higher color temperatures (over 5000K) are considered “cool” (i.e. Blue’ish). Lower color temperatures (under 5000K) are considered “warm” (i.e. orange’ish). Therefore if you are shooting indoors under tungsten lighting at 3200K you will set your white balance for indoor shooting at this color temperature. Is IPS or […]
What is the best type of insulator?
What is the best type of insulator? Aerogel is more expensive, but definitely the best type of insulation. Fiberglass is cheap, but requires careful handling. Mineral wool is effective, but not fire resistant. Cellulose is fire resistant, eco-friendly, and effective, but hard to apply. What is the highest rated wall insulation? Closed cell foam has […]
What are the 3 laws of electric charge?
What are the 3 laws of electric charge? Based on the same types of experiments like the one you performed, scientists were able to establish three laws of electrical charges: Opposite charges attract each other. Like charges repel each other. Charged objects attract neutral objects. What do you call a negative charge? Ion, any atom […]
Where is the gravitational pull on Earth the strongest?
Where is the gravitational pull on Earth the strongest? Arctic Ocean What is the force between Earth and the moon? According to Newton’s equation for calculating gravitational force (F), you will need four pieces of information: The gravitation constant (G) in Nm2/Kg2. The mass of object 1 (m1), in this case the mass of earth […]
