How often should you workout to see results? If you really want to see results reflected on the scale and continue to make progress over time, you need to commit to working out at least four to five days per week. But remember, you’ll build up to this. To start, you might only want to […]

What is an algorithm heuristic give an example? Christophides’ algorithm for the Traveling Salesman Problem, for example, used to be called a heuristic, as it was not proven that it was within 50% of the optimal solution. In practice, a heuristic may also be a sub-routine for an optimal algorithm, to determine where to look […]

Why is peristalsis so important? Peristalsis is an automatic and important process. It moves: Food through the digestive system. Urine from the kidneys into the bladder. How can I speed up peristalsis? If your transit time is a concern, there are some steps you can take to speed things up. Exercise for 30 minutes a […]

Is ice cream melting convection? The Answer: Heat Conduction. Your favorite scoop of ice cream melting on a hot summer day is a perfect example of heat conduction where heat from the air is naturally drawn to the much colder ice cream scoop. Is the sun conduction convection or radiation? The temperature of the atmosphere […]

How is electrical resistance calculated? R = V ÷ I Question What is the resistance of the lamp? To calculate the resistance of an electrical component, an ammeter is used to measure the current and a voltmeter to measure the potential difference. The resistance can then be calculated using Ohm’s Law. What is the total […]

What does an increase in aircraft weight do to V1? Since it concerns the runway, V1 is the first velocity speed a pilot must take into account. Temperature and wind speed are also factors, as are configuration of the airplane. The bigger the airplane, the higher V1 will be, since the airspeed depends on weight. […]

What is the direction of electric current? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in […]
