Why is there more current in a parallel circuit? In a parallel circuit, the potential difference across each of the resistors that make up the circuit is the same. This leads to a higher current flowing through each resistor and subsequently the total current flowing through all the resistors is higher. Why is USB faster […]

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 happens when energy is removed from a solid? What Is Freezing? The change of state from a liquid to a solid is called freezing. B. Removing Energy: Removing energy will cause the particles in a liquid to begin locking into place. What is normal freezing point of water? 32 °F. Can water freeze at […]
