Answer:

0.84 kg

Step-by-step explanation:

Given that :

Weight per liter = 1.12kg per liter

That is 1 Litre weighs 1.12 kilogram

The weight of saline solution of 0.75 Litre will be :

1 Litre = 1.12 kg

0.75 Litre = x

Cross multiply :

1 * x = 1.12 * 0.75

x = 0.84 kg

Hence, 0.75 Litre weighs 0.84 kg

If the radioactive half-life of a substance is 20 days, and there are 5 grams of it initially. When will the amount left be 2 gr
Kobotan [32]

Answer: 26.4\ \text{days}

Step-by-step explanation:

Given

Half life of radioactive substance is T_{\frac{1}{2}}=20\ \text{days}

Initial amount A_o=2\ \text{days}

Amount left at any time is given by

\Rightarrow A=A_o2^{\dfrac{-t}{T_{\frac{1}{2}}}}\\\\\Rightarrow 2=52^{\dfrac{-t}{20}}\\\\\Rightarrow 0.4=2^{\dfrac{-t}{20}}\\\\\Rightarrow 2^{\dfrac{t}{20}}=2.5\\\\\Rightarrow \dfrac{t}{20}\ln 2=\ln (2.5)\\\\\Rightarrow t=\dfrac{20\ln (2.5)}{\ln 2}\\\\\Rightarrow t=26.4\ \text{days}

It takes 26.4 days to reach 2 gm.

What is the slope of the line on this graph between 10 and 20 seconds?
Irina18 [472]

Answer:

3m/s

Step-by-step explanation:

delta y = 40m - 10m = 30m

delta x = 20s - 10s = 10s

slope = delta y / deltax = 30m / 10s = 3m/s
