What is the percentage of radioactive nuclei left after 3 Half Lives pass? Thus the half-life of a nuclear decay process is the time required for the number of unstable nuclei to decrease from [A]0 to 1/2[A]0….Radioactive Decay Rates. Number of Half-Lives Percentage of Reactant Remaining 2 50%2=25% 12(12)(100%)=25% 3 25%2=12.5% 12(12)(12)(100%)=12.5% n 100%2n (12)n(100%)=(12)n% […]
How do rivers become larger as they travel across the land?
How do rivers become larger as they travel across the land? 1 Answer. Tributaries combine, adding water to rivers. A tributary is a stream that flows into a larger river. Small streams from around an area combine together to form a bigger tributary that eventually falls into rivers. What kind of organism makes up the […]

Why can velocity be negative but speed can t?
Why can velocity be negative but speed can t? 2 Answers. Remember that velocity and acceleration are vectors, they have a magnitude and direction. Speed, on the other hand, is a scalar quantity which only has magnitude. So yes, the negative sign indicates a slowing down. What does it mean when position is negative? In […]
What is the resistance of two resistors in parallel?
What is the resistance of two resistors in parallel? Two identical resistors in parallel have an equivalent resistance half the value of either resistor. The current splits equally between the two. Does higher ohms mean more resistance? Ohms are units of resistance. The lower the resistance of your atomizer, the larger the amount of current […]
Is heat added or removed in condensation?
Is heat added or removed in condensation? A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Heat is released when a vapour condenses. What happens when a solid is heated Class 9? […]
What are the disadvantages of analog communication?
What are the disadvantages of analog communication? Disadvantages of Analog Signals Analog tends to have a lower quality signal than digital. The cables are sensitive to external influences. The cost of the Analog wire is high and not easily portable. Low availability of models with digital interfaces. How are digital signals transmitted wirelessly? In short, […]
