Answer:
0.1066 hours
Explanation:
A common pesticide degrades in a first-order process with a rate constant (k) of 6.5 1/hours. We can calculate its half-life (t1/2), that is, the times that it takes for its concentration to be halved, using the following expression.
t1/2 = ln2/k
t1/2 = ln2/6.5 h⁻¹
t1/2 = 0.1066 h
The half-life of the pesticide is 0.1066 hours.
Quantitative observations include numerical data. Ex: 32 degrees, 10 inches, etc.
Answer:
its already in scientific notation form however its ordinary or real form is -0.005682
Explanation:
scientific notation
when a number is expressed with some power of 10 multiplied by a number between 1 to 10 is called scientific notation
Answer:
The term sink refers to a location of carbon dioxide storage.
Thus option B is correct answer.
Explanation:
The term sink refers to a location of carbon dioxide storage. in carbon cycle where the carbon dioxide stored in the cycle that is called the sink.
in other words sink is also defined as the location of carbon products storage such as coal fossil fuel gases inside the earth is also known as the sink.
Thus sink behaves like the reservoir which stores carbon dioxide in the form of coal gases etc.
Thus option B is correct answer.
