Answer:
0.1gmin-1
Explanation:
mass = 0.5g
time = 5minutes
rate= mass/time = 0.1gmin-1
Answer:
Fiber optics is the technology used to transmit information as pulses of light through strands of fiber made of glass or plastic over long distances.
Explanation:
I did a test on it before
Answer:
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Wavelength = 188 μm
Also, 1 μm = 
nm
So,
Wavelength = 
m
Thus, Frequency is:
Answer:
you can classify a mineral by its appearance and other properties. The presence of a mineral is defined by the color and luster, and the color of the powdered mineral is described by the band. Every mineral has a distinctive density. To compare the hardness of rocks, the Mohs Hardness Scale is used.
Explanation:
This problem is easily solvable because radioactivity equations are common and well-established. The pseudo-first reaction is written below:
A = A₀(1/2)^(t/h)
where
A is the final amount
A₀ is the original amount
t is the time
h is the half life
5,000 = A₀(1/2)^(24,000/6,000)
Solving for A₀,
<em>A₀ = 80,000 atoms</em>
