prem gave 1/3 of his property for charity of the rest he gave 2/3 to his wife and rest divided equally between his son and daugh

Anna11 [10]

Given parameters:

Fraction given to charity = $\frac{1}{3}$

Fraction given to wife = $\frac{2}{3}$

Unknown:

Fraction given to son and daughter =?

Solution:

Let the total property = x

Fraction given to charity = $\frac{1}{3} x$

Fraction given to wife = $\frac{2}{3} x$

The remaining was given to son and daughter = F

So;

Total property = fraction given to charity + fraction given to wife + fraction given to son and daughter

x = $\frac{1}{3} x + \frac{2}{3} x + F$

F = x - ( $\frac{1}{3} x + \frac{2}{3} x$ )

F = 0

The son and daughter will not inherit anything

A NASA spacecraft measures the rate R of at which atmospheric pressure on Mars decreases with altitude. The result at a certain

AysviL [449]

Answer:

$R = 0.0000498 \frac{KJ}{ m m^3}=0.0000498 \frac{KJ}{m^4}=4.98x10^{-5}\frac{KJ}{m^4}$

Step-by-step explanation:

For this case we have the following value:

$R = 0.0498 \frac{Kpa}{Km}$

We can convert this first to $\frac{Kpa}{m}$ like this:

$R=0.0498 \frac{Kpa}{Km} *\frac{1km}{1000m}=0.0000498 \frac{Kpa}{m}$

Now we use the fact the the pressure is defined as $P =\frac{F}{A}$ , whre P is the pressure, F the force and A the area, so then $Kpa= \frac{KN}{m^2}$ and then we can replace this:

$R=0.0000498 \frac{KN}{m^3}$

Now from definition of work we know that $W= Fd$ where W is the work, F the force and d the distance, so then is equivalent $KN =\frac{KJ}{m}$

And if we replace this into the equation we got:

$R = 0.0000498 \frac{KJ}{ m m^3}=0.0000498 \frac{KJ}{m^4}=4.98x10^{-5}\frac{KJ}{m^4}$
