Will all the carbon-14 eventually disappear? The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay. After 50,000 years, a fossil won’t have any radiocarbon left in it. Carbon-14 will have all disappeared by radioactive decay. How can you tell how old a […]

What happens to a barrier island as sea level rises group of answer choices? What happens to a barrier island as sea level rises? Structures on the island are at risk due to increased erosion. Peat deposits are exposed on the ocean beach side of the barrier island. What will happen to the crust as […]

What are the two things needed for velocity? Since, velocity is a vector quantity, it has two components to it. The magnitude, which is the speed, and the direction in which the motion is happening. What 2 things does a person need to know to determine the velocity of an object? One must include direction […]

What are the factors on which internal resistance of cell depends? Thus, the internal resistance of a cell depends on the factors like distance between the electrodes, the temperature, the effective area of the electrodes and the concentration of the solution. Does internal resistance of cell depends on the current draw from the cell? No. […]

How much wood can you split in a day? Well yes you cut down and block out 5 cords a day with not much problem . However splitting it with just one person takes a tad bit longer than one day even with a hydraulic splitter . Hard wood like oak is right at 2 […]

What is range and how is it calculated? The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. How high can you throw a ball? Bradstock’s experience gives […]

Why has my energy bill doubled? Your energy bill usually reflects the amount of energy you’ve used. It’s normal for your bill to increase if, for example, you start: putting the heating on more often. using a tumble dryer or electric heater. Does heater or AC use more electricity? The simple answer to your first […]

What are the six properties of ionic compounds? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. Why are covalent […]

How far north does the Gulf Stream go? The Gulf Stream stretches 40 to 50 miles wide off the coast of southeast Florida as it chugs and snakes, ultimately toward Iceland, at a clip of 2 to 4 miles per hour. How fast is the current in the Gulf Stream? about 5.6 miles per hour […]

Is Ballistic an exact science? Ballistic is the science of the motion of the projectile and the condition that affects their motion. Ballistics is not an exact science rather it is branch of physics or applied science which is subject to changes and development depending upon the demands of the modern civilization. Does ballistic mean […]
