What is negative torque system? Definition. Negative Torque is said to occur when conditions are such that air loading on a propeller causes it to drive the engine to which it is attached vice the normal condition in which the engine drives the propeller. Which is better turboprop or jet? Less efficient & less cost-effective […]
Why is there 108 stitches on a baseball?
Why is there 108 stitches on a baseball? In total, 108 hand-stitched double stitches are used to cover the baseball. At the MLB level, these red stitches and the rest of what is used in a baseball are stored in temperature controlled facilities and wound under tension so no “soft spots” exist in the ball, […]
Which of the following will not affect the rate of evaporation?
Which of the following will not affect the rate of evaporation? Explanation: The rate of evaporation is depends on some factors like temperature, wind speed, surface area etc. But not on the mixed absolute heavy impurities. At what temperature does water start evaporating? 212° F How do you calculate the evaporation rate of water? I […]
How is density directly proportional to volume?
How is density directly proportional to volume? Density and Volume are inversely proportional to each other. Mass and volume are not the same. When density increases, volume decreases. When volume increases, density decreases. What do density mass and volume have in common? An object’s density is the ratio of mass to volume of an object. […]
Do all cells have cytoplasm?
Do all cells have cytoplasm? All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Why do all cells have cytoplasm? Cytoplasm works in plant cells much like it does in animal cells. It provides support to the internal structures, is the suspension medium for the organelles and maintains the shape of a cell. What […]

How Helmholtz double layer is formed?
How Helmholtz double layer is formed? Electrochemical Machining When a metal electrode is placed in an electrolyte solution, an equilibrium difference usually becomes established between the metal and solution. The positive charges of cations in the solution and the negative charges of electrons in the metal electrode form the electrical double layer [4]. What are […]

On January 22, 1973, the Supreme Court issued a 7–2 decision in favor of Norma McCorvey (“Jane Roe”) that held that women in the United States have a fundamental right to choose whether or not to have abortions without excessive government restriction, and struck down Texas’s abortion ban […]
How do you tell if it is exothermic or endothermic?
How do you tell if it is exothermic or endothermic? An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.” What does it mean when entropy is negative? A negative change in entropy indicates that the disorder of an isolated system has […]
How do you increase the amplitude of a sound wave?
How do you increase the amplitude of a sound wave? In theory, a sound wave can have any amplitude, and we can boost a wave by multiplying its samples with any arbitrarily large number. What is relation between frequency and voltage? As the voltage increases so does the power out of the area and frequency […]
