Which describes how a simple machine can make work easier? Explain how a machine makes work easier. Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. What are three ways machines make […]

How do you know if a road is 20 mph? There are no physical measures such as chicanes or humps in the roads that have been added to an original 20mph zone. Instead you’ll see road signs at the entry points into the 20mph zone, together with ’roundels’ or circles with ’20’ painted on the […]

How do you tell if an egg is boiled by spinning? Tip: Just place the egg on a hard surface, like the counter, and spin it like a top. As it’s spinning, grab it with your fingers ever-so-briefly and immediately let go. If it keeps spinning, it’s raw. If it stops dead, it’s boiled. How […]

Is rain water an acid or alkali? Not all rain can be considered pure water. Pure water is neither alkaline nor acidic. As rain falls from the atmosphere the impurities it collects changes the pH of the rain water, making it slightly acidic. How can we keep rain water clean? 5 Ways to Properly Store […]

What is cell surface charge? The surface charge can have either a negative or positive electrical state, which is determined by the balance between negatively charged and positively charged nanoparticles at the surface. The cell membrane surface of living cells has a different electric potential to the interior of cell, namely membrane potential. Are cells […]

What are the similarities and differences between electric and magnetic forces acting on a charged particle? Electric forces are created by and act on, both moving and stationary charges; while magnetic forces are created by and act on only moving charges. Electric monopoles exist. Magnetic monopoles don’t* exist. This is the reason that Maxwell’s laws […]
