What is the equation for the mechanical advantage of a lever? To calculate the mechanical advantage of levers, you can use one of two formulas. 1. Mechanical advantage = effort distance / resistance distance (MA = ED / RD) This formula is used when given meters. The distance of effort is the distance from the […]

Who is stronger Colossus or Juggernaut? According to the (Original) Official Handbook of the Marvel Universe (from the 80’s), Colossus could lift (press) 70 tons. He fought Juggernaut and lost, but held his own because of the durability of his Organic Steel form. Juggernaut has always been “class 100” strength (on par w/ Thor & […]

What to do if there is nothing to do? 40 Things To Do When You Have Nothing To Do Try to cook/bake something new. Listen to NPR. Write a letter to a family member or friend. Go through your clothes and get rid of what you don’t wear anymore. Watch BuzzFeed food videos on YouTube. […]

What is the best biomass to use for energy? Woody Fuels Wood wastes of all types make excellent biomass fuels and can be used in a wide variety of biomass technologies. Combustion of woody fuels to generate steam or electricity is a proven technology and is the most common biomass-to-energy process. How we can use […]

What are the advantages of scientific models? When students are engaged in scientific modeling, they are able to notice patterns and develop and revise representations that become useful models to predict and explain–making their own scientific knowledge stronger, helping them to think critically, and helping them know more about the nature of science. What are […]

What are examples of limiting factors on a population? Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. What are […]

What are the three types of generators? There are three main types of generators: portable, inverter and standby. Despite their differences, all these generators should undergo similar generator maintenance to ensure long-term usability, and similar safety precautions should be taken to reduce the hazards posed by their operation. What is the most efficient fuel for […]

What is the angle between tangent and normal? The normal is a line at right angles to the tangent. If we have a curve such as that shown in Figure 2, we can choose a point and draw in the tangent to the curve at that point. The normal is then at right angles to […]

How much force does it take to break a 1 inch board? A standard 12 by 12 white pine board takes about 1100 newtons (roughly 250lbs) of force to break. Because wood is a natural material, that varies a bit from board to board. A rule of thumb generally taught to martial artists is that […]

What is red shift and blue shift in UV VIS spectroscopy give examples? All Answers (10) Blue shift means increase in frequency, i.e., decrease in wavelength. On the other-hand, red shift denotes the reverse case (As, in visible spectra blue is at highest energy end, and red is at the lowest energy end). What causes […]
