Yakvenalex [24]

Answer:

Option C.

Step-by-step explanation:

From the given figure it is clear that

$PQ=5,QR=7,PS=4,ST=x$

So,

$PR=PQ+QP=5+7=12$

$PT=PS+ST=4+x$

Using Intersecting Secants Theorem, we get

$PQ\times PR=PS\times PT$

$5\times 12=4\times (4+x)$

$60=16+4x$

$60-16+4x$

$44=4x$

Divide both sides by 4.

$11=x$

$PT=4+x=4+11=15$

Since, x = 11; PR = 12; PT = 15, therefore the correct option is C.

curium-243 has a half-life of 28.5 days. In a sample of 5.6 grams of curium-243, how mamy grams will remain after 12 days?

Firdavs [7]

In this question, it is given that

Curium-243 has a half-life of 28.5 days. In a sample of 5.6 grams of curium-243.

And we have to use the following formula, which is

$A(t) = A_{0} (1/2)^{t/h}$

Here t=12 days, half life, h =28.5 days . And the initial value ,A(0)=5.6 gms

So we will get

$A(t) = 5.6(1/2)^{12/28.5}$

$A(t) = 5.6* 0.747 =4.2 gm$

Therefore after 12 days, 4.2 gmsof curium-243 remains .
