How do you add a function? Operations on Functions: Adding and Subtracting Functions Addition. We can add two functions as: (f + g)(x) = f(x) + g(x) Example: Subtraction. We can subtract two functions as: (f – g)(x) = f(x) – g(x) Example: Multiplication. (f•g)(x) = f(x)•g(x) Example: f(x) = 3x – 5 and g(x) […]

What is spectrophotometer and its uses?
What is spectrophotometer and its uses? A spectrophotometer is an analytical instrument used to quantitatively measure the transmission or reflection of visible light, UV light or infrared light. Applications for specs include measurement of substance concentration such as protein, DNA or RNA, growth of bacterial cells, and enzymatic reactions. What is spectroscopy principle? What Is […]
Why do we use FM?
Why do we use FM? Find Your Local Station: With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over […]
Which signal analog or digital is a more reliable way to transmit information?
Which signal analog or digital is a more reliable way to transmit information? Because of these things, digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information than analog signals. Digital signals are patterns generated by sampling a stream of continuous data at regular intervals. What is a disadvantage […]
Why can self-heating cans be used only once?
Why can self-heating cans be used only once? Answer: Self-heating food packaging is active packaging with the ability to heat food contents without external heat sources or power. Packets typically use an exothermic chemical reaction. Why self-heating cans are very expensive? Self-heating cans have dual chambers, one surrounding the other, making a self-heating food package. […]

Which light is not seen from the Earth?
Which light is not seen from the Earth? What Does Invisible Light Do? Electromagnetic waves are all around us. This includes not only visible light, but also invisible ultraviolet and infrared rays. Infrared rays, with wavelengths longer than visible light, are also a familiar part of electrical appliances. Are there stars we Cannot see? All […]
Is there a direct relationship between time in the air and the range?
Is there a direct relationship between time in the air and the range? There is no direct relationship between air time and range because when the initial angle changes, the initial velocity divides into x and y components. as x-velocity increase, the range increases up 5. What is the purpose of a motion graph? Describing […]
