Why does oxygen production stop without light? Plants produce oxygen as a waste product of making sugar using sunlight, carbon dioxide, and water. If a plant needs energy, but doesn’t have sunlight, then it can burn the sugar that it made back when it had sunlight, and doing so requires oxygen. What is an important […]
Why is density calculated from slope more accurate?
Which motor can rotate in both directions?
Which motor can rotate in both directions? DC motors How can the direction of DC motor be changed? We can change the direction of DC motor 1) by changing the polarity of applied field voltage. 2) by changing the polarity of the applied voltage to the armature winding. 3) if we change both of the […]
Is height positive or negative?
Is height positive or negative? An object’s height is a property of that object and has nothing whatsoever to do with the object’s motion. It’s correct to speak of the object’s displacement when describing motion. “Negative height” is always a meaningless term. Without specifying a coordinate system, “negative displacement” is almost as useless. Can work […]
Can water wick up hill?
Can water wick up hill? yes it can! In some ways anyway; water can travel upwards by a process called capillary action. Capillary action can be described as water climbing upwards due to weak forces created between the water molecules and the material the water moves up along, or through. Do wicking beds really work? […]
When is best time to salt driveway?
When is best time to salt driveway? The best time to treat the ground is before snowfall begins. Treating areas before snow (and freezing rain/ice) begins can help prevent ice from forming and prevent snow from settling. Because salt has a lower freezing point than water, it reduces the opportunities for moisture to freeze on […]
What is heat budget explain with the help of diagram?
What is heat budget explain with the help of diagram? A heat budget is the perfect balance between incoming heat absorbed by earth and outgoing heat escaping it in the form of radiation. If the balance is disturbed, then earth would get progressively warmer or cooler with each passing year. What is heat budget class […]
What is the true measure of success?
What is the true measure of success? It is as Stephen Richards says: “The true measure of success is how many times you can bounce back from failure.” It’s not about never experiencing a setback or a stormy day, it’s about learning to dance in the rain. What are the 5 key performance indicators? Top […]
What rules are applied in balancing equations?
What rules are applied in balancing equations? Balancing Chemical Equations Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation. What 4 guidelines […]
What order is the periodic table arranged?
What order is the periodic table arranged? The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency. […]
