the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.

Answer:
The effort distance (also sometimes called the “effort arm”) is shorter than the resistance distance. Mechanical advantage = |Fr/Fe | where | means “absolute value.” Mechanical advantage is always positive.
Answer:
2.4
Explanation:
To find the time above and below ymax/2 we use the following kinematic formula

Where
= Final Velocity
= Initial Velocity
= Gravity
= Time
Notice that we need to first find the values of velocity to solve this equation. To do that we use the following kinematic formula

Where
= Final Velocity
= Initial Velocity
= Gravity
= Height
Taking h = ymax/2 we get the following formula

To find the value of value of ymax in terms of v0 we use the law of conversation of energy

Now we can substitute the value of ymax

Now using the original equation to find time, we input the value of V1 and find time in terms of V0
Assuming final velocity v is 0 (since at the top velocity is zero)

This gives us total time from bottom to top
To find time from ymax/2 to top we substitute the value of V1

The time he is above ymax/2 is nothing more than the difference between t and t1

To find the required ratio we divide t1 by (t - t1)

Answer:
Light traveling through a vacuum moves at exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second
