Anabolic steroids. Steroid precursors. Amphetamines and other stimulants. Caffeine. Do drugs make you run faster? Using drugs to boost performance isn’t a new development. Steroids can help body-builders to […]

How are goods allocated if Qd Qs? When the supply and demand curves intersect, the market is in equilibrium. This is where the quantity demanded and quantity supplied are equal. The corresponding price is the equilibrium price or market-clearing price, the quantity is the equilibrium quantity. Quantity supplied is equal to quantity demanded ( Qs […]

How do you do equations with two variables? If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called […]

What angle is the sun at noon? 90 degrees What is the importance of sun path diagram? Sun path diagrams provide a broader overview of sun on a site as they map the path of the sun across the sky at different times during the day throughout the year. What is the most exact projection […]

How does a cannonball kill? Typically fired from a mortar or howitzer, it gave you the ability to fire at a much more oblique angle – flinging your shots over the battlefield rather than in the straight lines of your traditional cannon. This mean the shells would explode within the enemy formations (or even above […]

What is the formula of resultant? →F=→F1+→F2+→F3…. Depending on the number forces acting, the resultant can be obtained geometrically by applying triangle law, parallelogram law or polygon law of vector addition. Note that the magnitudes of the forces cannot be added or subtracted unless they are collinear. What is the resultant of 3 vectors? Adding […]

Will a water balloon pop in the freezer? Will a water balloon pop in the freezer? Water expands when it freezes, so if you fill the balloon too much, it will burst as the water expands. How long does it take to freeze a balloon full of water? Step 2: Freezing the Balloon When you […]

What are the characteristics of electrical energy? Electrical energy is energy that comes from electrical potential energy. This energy is generated by the movement of positive and negative particles or electricity. Once electrical energy leaves its source, it is instantly transformed into a different kind of energy. Why is electrical energy popular? Electrical energy is […]
