How do you know if a gas is ideal? For a gas to be “ideal” there are four governing assumptions: The gas particles have negligible volume. The gas particles are equally sized and do not have intermolecular forces (attraction or repulsion) with other gas particles. The gas particles move randomly in agreement with Newton’s Laws […]

How many miles can you bike in 30 minutes? six miles Do lighter bikes go faster? In fact, he did the math to see just how much speed a cyclist can save with a lighter bike. Even at the steepest grade he tested (7 percent), a one-pound difference between bikes only saves about 2.5 seconds—and […]

How do you determine the direction of a magnetic force? We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force […]

What is the function of UV light? UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. Different UV wavelengths and intensities are used for different purposes. Can you get vitamin D […]

What is the formula for distance Travelled? To solve for distance use the formula for distance d = st, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed […]

How much should a car battery drain overnight? If its a new battery with a good charging system 12.8 to 12.6 is what you should expect. The problem is in order to save fuel a lot of charging systems only charge your battery 80% to save fuel. How do I know if I need a […]

What is the perfect amount of water for bottle flipping? Fill a plastic water bottle about one quarter to one third full with water and put the cap on tightly. Hold the bottle loosely by the neck, and toss it forward (so the bottom rotates away from you). Try to throw the bottle so that […]

What are the most common two letter words? The most common two-letter words are of, to, in, it, is, be, as, at, so, we, he, by, or, on, do, if, me, my, up, an, go, no, us, am. The most common three-letter words are the and and. Which vowel is used least? Z What are […]

What 4 things are needed for photosynthesis? For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun). What are the three end products of photosynthesis? Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is […]

How energy is transformed in our body? All of the body processes, like digestion, pumping blood, breathing, are powered by cells converting the stored chemical energy into work and heat, in a process called respiration. Inside the muscle cells of the human (or any animal), the chemical energy is transformed (changed) into mechanical work and […]
