Answer:
water will remain for more time on earth
Explanation:
this is the correct answer you want.
Answer:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
Explanation:
The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time (
), in grams, is described below:
(1)
Where:
- Initial mass, in grams.
- Time, in years.
- Time constant, in years.
The time constant can be found from half life (
), in years, described in statement:
(2)
If we know that 
, 
and 
, then the current amount of the sample is:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
Many intervening variables that could affect the performance of a freely suspended compass and achieve a linear measurement. Some of these variables are enumerated below but not limited to these items.
1. Temperature Induced
2. Current Stabilization
3. Temperature effects on the materials
4. AC and DC
Four major parts of Earth work together as a complex system: rocks, water, air, and life.
The four parts are called the geosphere,hydrosphere<span>, </span>atmosphere, and biosphere.
Rocks- Geosphere
Water- Hydrosphere
Air- Atmosphere
Life- Bioshpere
