How do you find the median score? Median Arrange your numbers in numerical order. Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2. Go to the number in that […]
What do you mean by Doppler shift?
What do you mean by Doppler shift? When a body that is emitting radiation has a non-zero radial velocity relative to an observer, the wavelength of the emission will be shortened or lengthened, depending upon whether the body is moving towards or away from an observer. This change in observed wavelength, or frequency, is known […]
How many ignition coils are used in waste spark systems to fire the spark plugs for two cylinders at the same time?
How many ignition coils are used in waste spark systems to fire the spark plugs for two cylinders at the same time? A waste-spark system fires one coil for each pair of cylinders that are at top dead center (TDC) at the same time. These cylinder pairs are called “running mates.” One cylinder is at […]
How do I calculate my kWh?
How do I calculate my kWh? Calculating Kilowatt Hour Rate The kilowatt-hour rate is the price of power supplied by your electric provider. To calculate your kilowatt-hour rate, divide your total power bill, minus any taxes, by your total power consumption. Do heat lamps cause cancer? While UV can cause cancer if human beings are […]
Where are pulleys used today?
Where are pulleys used today? Many types of exercise equipment use pulleys in order to function. Construction pulleys are used in order to lift and place heavy materials. Curtains at a theatre are moved using pulley systems that pull the curtains apart. Blinds on windows operate using a pulley system to move the blinds up […]
What color is the sky to a colorblind person?
What color is the sky to a colorblind person? blue What does a stop light look like to a colorblind person? Usually colorblind drivers employ strategies like noticing the vertical placement of the lights. For example, with a U.S. traffic light: red is on top, followed by yellow in the middle, then green at the […]
How do you solve rate problems?
How do you solve rate problems? All rate problems can be solved by using the formula D = R(T), which translates to distance (D) equals rate (R) multiplied by time (T). How do you use ratios and rates to solve problems? Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in […]
Is sunlight a transverse wave?
Is sunlight a transverse wave? As it turns out, there are two directions for light waves to oscillate and, consequently light is a transverse wave. Is period transverse or longitudinal? Period and Frequency The period of a longitudinal wave is the time taken by the wave to move one wavelength. As for transverse waves, the […]
How can the mechanical advantage and efficiency of a machine be increased?
How can the mechanical advantage and efficiency of a machine be increased? The mechanical advantage increases as the slope of the incline decreases. But the load will then have to be moved a greater distance. The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, […]
What is the important of cell membrane?
What is the important of cell membrane? The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell. Why is […]
