Rounded to 1 significant figure, 25 m would go to 30. This is because 0 isn't significant, so the 3 is the only significant figure.
The artifact appears to have gone through 2 half-lives.
One half-life for Carbon-14 is 5730 years.
After 5730 years, there would be 1/2 as much carbon-14
After another 5730 years, there would be 1/4 as much carbon-14
The answer is roughly 11,460 years
Answer:
the chemical equation is balanced ❤
Answer:
317.7778 g
Explanation:
Given data:
Flour required for 18 cup cakes = 260 g
Flour required for 22 cup cakes = ?
Solution:
We will calculate the flour required for 1 cup cake.
260 g /18 = 14.4444 g
Fluor required for 22 cupcakes,
22× 14.4444 g = 317.7778 g
In short,
22 cupcake/18 cup cake×260 g = 317.7778 g
The correct answer to the question above is
:
(c.) agriculture.
Agriculture is the greatest use of groundwater. Groundwater is a water found in the underground or beneath the Earth's surface, in the cracks and soil spaces.
Explanation:
Food and agriculture are the largest purchasers of water, requiring one hundred times more than we use for individual needs. Up to 70 % of the water we take from rivers and groundwater goes into irrigation, about 10% is used in residential applications and 20% in industry. Groundwater is the water today underneath Earth's outside in soil pore spaces and in the fractures of rock structures. A unit of rock or an unconsolidated alluvium is described as an aquifer when it can generate a usable quantity of water.
