Is the sciencetjfic law and security theory the same?
TRUE
I think their distance is a measurement of : B. space in two dimension
In two-dimensional space, both directions located in the same plane , and the distance in locations only separated by width and length (there is no volume in this model)
Answer:
A neutral object has the same charge. A positively charged object have positive charges called electrons. A negatively charged object have negative charges called protons.

mass is required for activity of 315 ci
The activity of the radioactive substance is the number of disintegrations taking place in a radioactive sample.
Isotopes are the members of an element having the same number of protons but the different number of neutrons.
the activity of the radioactive sample is given as:
A = λ * N
where λ is the decay constant and N is the number of disintegrations.
activity is given as 315 ci
A = 315 * 3.7 * 
= 1165.5 *
Bq
λ = 0.693 / 
= 0.693 / 2.69 * 24 * 3600
= 2.98 *
t^-1
Therefore, N = A / λ
= 1165.5 *
/ 2.98 * 
N = 391.12 * 
391.12 *
mass is required for activity of 315 ci
