How do you identify a metal? Take your piece of metal and test its magnetization by sticking a magnet to it. If your metal sticks to the magnet, the metal could be cast iron or steel. If the metal does not stick to the magnet, your metal could be copper, brass, solver or aluminum. What […]
What shows up white on an ultrasound?
What shows up white on an ultrasound? Highly dense tissues such as bone or kidney stones readily reflect echoes and, therefore, appear bright white on an ultrasound. Air, such as in the bowel, also readily reflects echoes. The edge of the bowel, therefore, appears white on an ultrasound. How can you tell on an ultrasound […]
What would happen to the pressure of a gas inside a sealed bottle if the bottle was squeezed tightly?
What would happen to the pressure of a gas inside a sealed bottle if the bottle was squeezed tightly? Answer: The pressure would increase because the volume of space the gas takes up decreases once the bottle is squeezed. There is less room for the gas particles to move around meaning more collisions between the […]
What metals are used in lamps?
What metals are used in lamps? Common Materials for Lighting Fixtures & Components Aluminum: As an all-around well-performing metal, aluminum is one of the most commonly used materials for stamped lighting fixtures. Cold Rolled Steel: Cold rolled steel is an ideal metal for lighting fixture applications where production precision is critical. What wood is used […]
What is bulk resistance?
What is bulk resistance? The Bulk Resistance, rB, of a diode is the approximate resistance across the terminals of the diode when a forward voltage and current are applied across the diode. The bulk resistance represents the resistance of the p and n materials of the p-n junction of the diode. What is dynamic resistance […]
Do cows produce more greenhouse gases than cars?
Do cows produce more greenhouse gases than cars? Hence, according to the United Nations Food and Agriculture Organization (FAO) livestock generate 18 percent of total greenhouse gas emissions as measured in CO2 equivalents — more than the entire transport sector, automobiles, trains, ships, and planes. What is the biggest contributor to CO2 emissions? China What […]

Does vitamin D change skin color?
Does vitamin D change skin color? Light skin color was reported by 88% of the women with sufficient vitamin D levels and by 66.6% with vitamin D deficiency. Does low vitamin D cause anxiety? Higher levels of anxiety, depression and internalizing problems but not atypicality were associated with lower levels of vitamin D. Vitamin D […]
How do you find the standard form of an equation?
How do you find the standard form of an equation? The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). How do you find the standard […]
Does total internal reflection occur in rainbow?
Does total internal reflection occur in rainbow? Answer. The rainbows we see are not formed by light from a single drop of water, but by light from a whole cloud of water drops, emerging in many directions. So any ray entering the drop cannot subsequently ever impinge on the surface at an angle where there’s […]
