The age of a piece of wood from an archeological site is to be determined using the Carbon-14 method. The activity of the sample
Bezzdna [24]

Answer:

4589.05 year

Explanation:

The relation of activity is given by A=A_0e^{\lambda t} we have given \frac{A}{A_0}=0.574

Half life T=5730\ years

We know that half life T=\frac{0.693}{\lambda }

\lambda =\frac{0.693}{5730}=1.2094\times 10^{-4}\ per\ year

So 0.574=e^{-1.2094\times 10^{-4}t}

e^{1.2094\times 10^{-4}t}=\frac{1}{0.574}=1.742

{1.2094\times 10^{-4}t}=ln1.742=0.555

t=\frac{0.555}{1.2094\times 10_{-4}}=4589.05\ year

Two charged particles have a repulsive force of 5.7 newtons. The charge of one particle is multiplied by 8.5, and the distance b
Diano4ka-milaya [45]

You can do this all in one Step

Formula

F2/F1 = 8.5/(25r^2) // 1 / r^2

Solution

\dfrac{F2}{F1} = \dfrac{\dfrac{k8.5*q1*q2}{(5r)^2}}{\dfrac{k*q1*q2}{r^2} }

The "ks, r^2 and q1 q2" all cancel out

You are left with 8.5/25 as the ratio

  • F1 = 5.7 N
  • F2 = 8.5 / 25  * F1
  • F2 = 8.5 / 25 * 5.7
  • F2 = 1.938
