Ksju [112]

Answer:

i am not sure of these answer but what i know i am gonnna share eith you

Step-by-step explanation:

. The people relied on primitive accounting methods to record the growth of crops and herds. Because there was a natural season to farming and herding, it was easy to count and determine if a surplus had been gained after the crops had been harvested or the young animals weaned.

2. The use of the words "debit" and "credit" in accounting goes back to the days of single-entry bookkeeping, which had as its chief objective keeping track of amounts owed by customers (debtors) and amounts owed to creditors.

3. Accounting as an ad-hoc ordering system devised by the merchant. Its regular use provides the merchant with continued information about business, and allows to evaluate how things are going and to act accordingly.

Radium-228 has a half-life of 5.75 years. What is the decay rate for radium-228?
artcher [175]

Decay rate for Radium-228 is 0.01205

Step-by-step explanation:

The half life of radium-228 is 5.75 years. We need to find the decay rate for radium.

The formula used is:

ln\frac{N_o}{N_t}=-\lambda t

Where N₀ = amount of radioactive particles at time = 0

N_t = amount of radioactive particles are time (t)

λ = rate of decay constant

t = time

We are given half life so, \frac{N_o}{N_t}=0.5

t= 5.75 years

We need to find λ

Putting values in formula and solving:

ln\frac{N_o}{N_t}=-\lambda t

ln(0.5)=-\lambda *5.75\\-\lambda=\frac{ln(0.5)}{5.75}\\-\lambda=\frac{-0.69}{5.75}\\-\lambda=-0.1205\\\lambda=0.1205

So, Decay rate for Radium-228 is 0.01205.
