How do you calculate a mix ratio? Divide 1 by the total number of parts (water + solution). For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9). How do you calculate […]

What makes hair follicles grow? Your hair begins growing from a root in the bottom of the follicle. Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow. How can I reopen my hair follicles naturally? Their proven benefits can help to stimulate growth and […]

What takes up the most water in a house? The largest use of household water is to flush the toilet, followed by taking showers and baths.

What is the unit for carbon footprint? tonnes What is your water footprint? Your water footprint is the amount of water you consume in your daily life, including the water used to grow the food you eat, to produce the energy you use and for all of the products in your daily life – your […]

What is the major disadvantage of UV light as a disinfectant sterilant? Disadvantages of UV disinfection? UV light needs the right amount of energy to be effective. UV light is effective for microorganisms not for chemicals. Photochemical damage caused by UV may be repaired by some organisms. Is UVC air purifier safe? It’s questionable. The […]

Is relative pitch better than perfect pitch? Here’s a simple way to think about it: for a singer, absolute perfect pitch means you can pluck an existing note out of the air and sing it in tune very accurately, while relative pitch means that a singer could hear an existing note and then use it […]

Which state is not a physical state of matter? There is water vapor above a pot of boiling water. That vapor (or gas) can condense and become a drop of liquid water in the cooler air. If you put that liquid drop in the freezer, it would become a solid piece of ice. No matter […]

Is an LED a passive component? Some examples of active devices include solenoids, relays, LEDs, and microcontrollers or any other integrated chip that uses an external supply voltage (or current) to perform work or the intended function. LEDs are light emitting diodes, and we state above that diodes are considered passive. What are the different […]

How many chromosomes does meiosis start with? 46 chromosomes Are cells haploid after meiosis? By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the […]

What are the factors that affect the notched bar impact test? Factors Affecting Charpy Impact Energy Yield strength and ductility. Notches. Temperature and strain rate. Fracture mechanism. How can impact resistance be improved? To improve the impact resistance, manufacturers often use three ways to overcome it: Copolymer modification: It is modified during the synthesis of […]
