vodomira [7]

Answer:

A sample of 5.2 mg decays to .65 mg or to 1/8 of its original amount.

1/8 = 1/2 * 1/2 * 1/2 or 3 half-lives.

3 * 30.07 = 90 yrs for 5.2 mg to decay to .65 mg

You can get these other numbers similarly:

5.2 / .0102 = 510 requires about 9 half-lives which is 30 * 9 = 270 yrs

two punds of water vapor at 30 psia fill the 4ft3 left chmaber of a partitioned system. The right chmaber has twice the volume o

tamaranim1 [39]

Answer:

pressure of water will be 49.7 atm

Explanation:

given data

pressure = 30 psi = 2.04 atm

water = 2 pound = 907.18

mole of water vapor = 907.19 /2 = 50.4 mole

volume = 4 ft³ = 113.2 L

temperature = 40 F = 277.59 K

to find out

pressure of water

solution

we will apply here ideal gas condition

that is

PV = nRT .......................1

put here all value and here R = 0.0821 , T temperature and V volume and P pressure and n is no of mole

and we get here temperature

PV = nRT

2.04 × 113.2 = 50.4×0.0821×T

solve it and we get

T = 55.8 K

so we have given right chamber has twice the volume of the left chamber i.e

volume = twice of volume + volume

volume = 2(113.2) + 113.2

volume = 339.6 L

so from equation 1 pressure will be

PV = nRT

P(339.6) = 50.4 × ( 0.0821) × (277.59)

P = 3.3822 atm = 49.7 atm

so pressure of water will be 49.7 atm

A negative point charge q1 = 25 nC is located on the y axis at y = 0 and a positive point charge q2 = 10 nC is located at y =14

sergey [27]

Answer:

y = 0.1 m

Explanation:

The electrical power for point loads is

V = $k \sum \frac{q_i}{r_i}$ k Sum qi / ri

in this case

V = k ( $- \frac{q_1}{r_1 } + \frac{q_2}{r_2}$ )

indicate that V = 0

$\frac{q_1}{r_1} = \frac{q_2}{r_2}$

r₂ = $\frac{q_2}{q_1} r_1$

the distance r1 is

r₁ = y -0

the distance r2

r₂ = 0.14 -y

we substitute

0.14 - y = $\frac{10}{25}$ y

y ( $\frac{10}{25} + 1$ ) = 0.14

y 1.4 = 0.14

y = 0.14 / 1.4

y = 0.1 m
