Can you over boil potatoes?
Can you over boil potatoes? 2. Don’t Overcook or Undercook the Potatoes. If they’re undercooked, you’ll have pockets of crispy potato chunks-a big no-no for classic fluffy mashed potatoes. If you overcook them they disintegrate and your potatoes will be soupy. Should you peel potatoes before boiling? Some people may prefer to peel the potatoes […]
What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]
What is the purpose of mitosis and meiosis?
What is the purpose of mitosis and meiosis? The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less. Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and […]
Can the resultant of 3 vectors be zero?
Can the resultant of 3 vectors be zero? Answer. Three vectors are coplanar which means all three vectors are in the same plane. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be […]
What is Lambda fuel ratio?
What is Lambda fuel ratio? Lambda represents the ratio of the amount of oxygen actually present in a combustion chamber compared to the amount that should have been present in order to obtain “perfect” combustion. Thus a lean air/fuel ratio of, say, 16:1 would translate to a lambda value of 1.088. (To calculate, divide 16 […]
What is the horizontal velocity of a projectile?
What is the horizontal velocity of a projectile? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent […]
What does a four-stroke cycle do?
What does a four-stroke cycle do? An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. As the piston moves during each stroke, it turns the crankshaft. Do spark plugs fire every cycle? For gasoline and other non-diesel engines, spark plugs fire once every combustion cycle. Once the engine is warmed up […]
