What happens to the surface area of a cube as its height doubles?
If the height of a cube doubles and becomes a square prism instead of a cube, four of the six original equal area surfaces double in area, but the other two are unchanged. Therefore the area of the square prism is (2/3) X 2 = 4/3 as great as the original cube. If the original object is to remain a cube when its height doubles, all the other dimensions must also double; in that instance, the area increases by a factor of four.
The half-life of radon - 222 is 3.823 days. What is the length of 4- half-lives?
The length of four half-lives of radon-222 can be calculated by multiplying the half-life duration by four. Since the half-life of radon-222 is 3.823 days, four half-lives would be 4 × 3.823 days, which equals approximately 15.292 days.
What is the half-life of sodium-25 if 1.00 gram of a 16.00-gram sample of sodium-25 remains unchanged?
The half-life of sodium-25 can be determined by the decay of the sample. If 1.00 gram remains from an initial 16.00-gram sample, then 15.00 grams have decayed. This means that 1.00 gram represents ( \frac{1}{16} ) of the original sample, which indicates that the sample has gone through four half-lives (since ( \frac{1}{2^4} = \frac{1}{16} )). Therefore, if the time taken for these four half-lives is known, the half-life can be calculated as one-fourth of that total time.
What are the four words found on the cenotaph?
The four words found on the cenotaph are "The Glorious Dead." These words honor those who lost their lives in military service, commemorating their sacrifice and bravery. The cenotaph serves as a memorial to acknowledge and remember the fallen soldiers.
Is a rectangular solid a polygon?
A rectangular solid is a polygon, as it is a four-sided, six face object. In two dimensions, it will remain a polygon with intersecting lines at the interior, with no line exceeding the boudary of the edge of the object from any point of view.
The half-life of radium-226 is 1620 years. How much of one gram of radium-226 will remain unchanged after four half-lives?
After 4 half-lives, the amount remaining is ( (1/2)^4 ), which equals 1/16. Therefore, 1 gram of radium-226 will have 1/16 gram unchanged after four half-lives, which is 0.0625 grams.
How much of one gram of radium-226 will remain unchanged after four half-lives?
After each half-life, half of the radium-226 will decay. Therefore, after four half-lives, 1/2^4 or 1/16th of the original gram of radium-226 will remain unchanged. This means that 1/16th of a gram, or 0.0625 grams, will still be unchanged after four half-lives.
Four pronouns which have remained unchanged from Old English are?
Me Us We He His Him
How many milligrams of a 15.0 mg sample of radium-226 remain after 6396 years if the half-life of radium-226 is 1599?
One sixteenth of a gram. 1st halflife- 1/2 gram 2nd, 1/4 3rd 1/8th 4th halflife, 1/16th

What is the first decay product of radium?
Radium decays in any of (at least) four different ways, depending on isotope and, in some cases, on luck, as some isotopes can decay in different ways. The most important way radium can decay is by alpha emission. Nearly all naturally occurring radium decays this way, and so do the majority of synthetic isotopes. In this case, radium emits an alpha particle, which can be regarded as a helium nucleus, and the daughter atom is radon. The isotope of radon is depends on the isotope of radium involved; the mass number of the radon is always equal to the mass number of the radium minus four. Some heavier radium isotopes undergo negative beta decay, in which case the decay products are an actinium atom and a negative beta particle, which can be viewed as an electron. Some lighter radium isotopes undergo positive beta decay, in which case the decay products are a francium atom, a positive beta particle, which can be viewed as a positron, and an electron type antineutrino. A few radium isotopes also rarely undergo what is called cluster decay, and the most important naturally occurring isotope, radium-226 is among these. Cluster decay involves emission of a nucleus larger than an alpha particle, and in the case of radium all known cluster decays emit carbon-14 nuclei. In this case, the daughter atom is lead, with a mass number that is 14 lower than the mass number of the parent. So radium-226 can emit a carbon-14 nucleus, leaving a lead-212 atom.
What actors and actresses appeared in Four Lives of Cindy - 1989?
The cast of Four Lives of Cindy - 1989 includes: Cindy Prince
How long does xanax stay in your body only took for 4 months at 0.25milligrams a day for anxiety?
it will be in your system for about four days. The half life is sixteen hours and a drug can only remain in your system for six half lives, therefore four days is your answer, it could be quicker if your thin and slower if your fat
Near the end of page 124 of your reading material you are shown a calculation to determine a car's final speed after accelerating for four seconds. If everything else in the problem remained the same.?
The final speed of the car would be unchanged because the time taken to accelerate does not affect the other variables such as initial speed, acceleration, and distance travelled. The calculation to determine the final speed only depends on these variables, so if they remain constant, the answer will also remain the same.
