What is the magnitude of vector K ?

vovangra [49]

Answer:

Vector K = 8 m

Explanation:

The given figure shows a right angle triangle JKL. It is given that :

vector L = 10 m

vector J = 6 m

We have to find vector k. We can find it by using Pythagoras theorem. According to this theorem, the sum of squares of perpendicular and the base is equal to the square of the longest side.

$L^2=K^2+J^2$

$K^2=L^2-J^2$

$K^2=(100)^2-(6)^2$

K = 8 m

Hence, the magnitude of vector K is 8 m.

If the conductivity of the solution is NOT affected by increasing the solute concentration, what does that indicate about both t

Alexeev081 [22]

<u><em>Both solvent and solute are parts of a solution.</em></u> Solutions are mixtures of two or more substances, and the substance that dissolves into the solution is a solute. Meanwhile, the solute dissolves into a s Meanwhile, the solute dissolves into a substance called the solvent.

Solutes and solvents are substances not used only in chemical laboratories, but they are part of the day to day life. A solution contains only two components, which are solute and solvent. Solvent has the capability of dissolving the solute in a homogenous solution.

The logarithm of x, written log(x), tells you the power to which you would raise 10 to get x. So, if y=log(x), then x=10^y. It i

fomenos

To solve this problem it is necessary to apply the rules and concepts related to logarithmic operations.

From the definition of logarithm we know that,

$Log_{10}(10) = 1$

In this way for the given example we have that a logarithm with base 10 expressed in the problem can be represented as,

$log_{10}(1,000,000)$

We can express this also as,

$log_{10}(10^6)$

By properties of the logarithms we know that the logarithm of a power of a number is equal to the product between the exponent of the power and the logarithm of the number.

So this can be expressed as

$6*log_{10}(10)$

Since the definition of the base logarithm 10 of 10 is equal to 1 then

$6*1=6$

The value of the given logarithm is equal to 6
