Answer:
Pecan trees 1 and 4
Explanation:
1: 1 and 4
2a: With good soil and good parent plants
2b: Heredity
Half life is the time taken for a radioactive isotope to decay by half its original mass. In this case the half life of carbon-14 is 5.730 years.
Using the formula;
New mass = original mass × (1/2)^n; where n is the number of half lives (in this case n=1 )
New mass = 2 g × (1/2)^1
= 1 g
Therefore; the mass of carbon-14 that remains will be 1 g
Answer:
1. Tropical Climate
Explanation:
Due to the high heat in tropical climates, the moisture speeds up chemical weathering
Answer:
Given:
Mass = 14.0 g
Density (
) = 1.38 g/cm³
To Find:
Volume (V)of the plastic used to make water bottle
Explanation:
Formula:
Substituting value of m & density in the formula:
Volume of the plastic used to make water bottle = 10.14 cm³
