The number of radioactive nuclides from a radioactive source has reduced to 1/6 from its original value in 60 seconds. Find the decay constant for this source.​

λ = 0.03 s⁻¹

Explanation:

The formula for decay constant can be used as follows:

where,

= ratio of remaining nuclei to the initial value of nuclei = = 0.167

t = time = 60 s

λ = decay constant = ?

Therefore,

λ = 0.03 s⁻¹

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
