Find the magnitude of wx for w(-3 5 4) and x(9 5 3)

Hatshy [7]

Answer: Magnitude of wx is $\sqrt{145}$

Step-by-step explanation:

Since we have given that

$w(-3,5,4)=-3\hat{i}+5\hat{j}+4\hat{k}\\\\x(9,5,3)=9\hat{i}+5\hat{j}+3\hat{k}$

Now, first we will find 'wx':

$wx=Initial-Final\\\\wx=(9+3)\hat{i}+(5-5)\hat{j}+(3-4)\hat{k}\\\\wx=12\hat{i}-1\hat{k}$

We need to find the "magnitude":

$\mid wx\mid=\sqrt{12^2+1^2}=\sqrt{144+1}=\sqrt{145}$

Hence, Magnitude of wx is $\sqrt{145}$

Whats the density of an object with the length of 5.0 cm a height of 3.0 and width of 15.0 cm and a mass of 24 grams

Sphinxa [80]

Answer:

The density of the object is $0.1067$ grams per cubic centimeter. (Rounded off to 4th decimal)

Step-by-step explanation:

Density = [Mass/Volume]

Here we have been given the dimensions of the object.

Volume = Height * Width * Length

Volume = $3.0cm*15.0cm*5.0cm$

= $225cm^{3}$

Now we can substitute the Mass and the Volume to the density equation.

Density = [Mass/Volume]

= $\frac{24grams}{225cm^{3} }$

= $0.1067$ grams per cubic centimeter. (Rounded off to 4th decimal)
