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 […]
What is used to measure mass?
What is used to measure mass? Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder. What should be weight as per height? Weight and height guide chart Height Weight 5ft 2″ (62″) 104 to 131 […]
How many chromosomes does meiosis start with?
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?
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 […]
What is mean by free fall a ball is dropped from the roof of a building it takes 10 seconds to reach the ground find the height of the building?
Could the UK have a major earthquake?
Could the UK have a major earthquake? The British Geological Survey said: “A magnitude 4 earthquake happens in Britain roughly every two years. We experience a magnitude 5 roughly every 10–20 years. Research suggests that the largest possible earthquake in the UK is around 6.5.” What is the safest place on earth? European countries dominate […]
What is the significance of RMS value?
What is the significance of RMS value? The RMS value is the effective value of a varying voltage or current. It is the equivalent steady DC (constant) value which gives the same effect. For example, a lamp connected to a 6V RMS AC supply will shine with the same brightness when connected to a steady […]

How does a thermos keep the liquid inside of it warm?
How does a thermos keep the liquid inside of it warm? A thermos is a bottle with a double-walled container inside of it. The air between the two walls is sucked out during construction, creating a vacuum. Instead of containing some kind of heating element to keep hot things hot, a thermos is designed to […]
