The answer that would best complete the given sentence above is cubic meter. The standard unit for measuring volume is the cubic meter (m^3). Volume is the quantity or the measurement of the amount of space that can be or is being occupied by matter. The metric unit for volume includes "liters" and "milliliters".
Answer:
6.7 x 10^8 mi/hr
Explanation:
Do the math with units ONLY
km/s * miles/ km * s/hr = mi / hr ( ...as the km and s cancel out)
now.... put in the numbers
3 x 10^5 km/s * .62 mi/km * 3600 s / hr = 6.7x 10 ^8 mi/hr
<h2>
Answer: 450 Bq</h2>
Explanation:
This problem can be solved using the Radioactive Half Life Formula:
(1)
Where:
is the final amount of radioisotope (decay rate)
is the initial amount of the radioisotope
is the time elapsed
is the half life of the radioisotope
Knowing this, let's find from (1):
(2)
(3)
Finally:
>>> This is the decay rate of the radioisotope
Note it is in Becquerels (Bq), which is the derived unit approved by the <u>International System of Units</u> for radioactivity
it would be c hope it helps
