Answer : The half life of 28-Mg in hours is, 6.94
Explanation :
First we have to calculate the rate constant.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = time passed by the sample = 48.0 hr
a = initial amount of the reactant disintegrate = 53500
a - x = amount left after decay process disintegrate = 53500 - 10980 = 42520
Now put all the given values in above equation, we get
Now we have to calculate the half-life.
Therefore, the half life of 28-Mg in hours is, 6.94
Answer: plate
Explanation: Plates grinding past each other in opposite directions create faults called transform faults. Powerful earthquakes often strike along these boundaries. The San Andreas Fault is a transform plate boundary that separates the North American Plate from the Pacific Plate.

Answer:
An example of an energy transformation that occurs in the natural world is the process of photosynthesis. In the Sun, chemical energy transforms into light and thermal energy. Plants transform the Sun's light energy into chemical energy during the process of photosynthesis.
Explanation:
Answer:
The difference is the combining vowel
Explanation:
The Combining form needs the vowel to form, that is:
root word + combining vowel = combining form
<u>Root word</u>:
A root is a word that does not have a prefix in front of the word or a suffix at the end of the word. The root word is the main lexical unit of a word and a family of words, which carries the most significant aspects of semantic content and cannot be reduced to smaller components
<u>Combining form</u>:
Training process of words from two or more roots or simple words.
When the word includes a cultured base and a patrimonial base, we will consider derived word. For example, hypermarket, bi-monthly
