What Force would be needed to extend a spring with a spring constant k=7 N/m that extends 0.3m?

vladimir2022 [97]

Answer:

Force = - 2.1 Newton

Step-by-step explanation:

According to question ,

The value of Spring constant , K = 7 N/m Newton per meter

And the spring is extended up to 0.3 meter

The Force experience on the spring is calculated from the Hook's Law

The principal state that , the force applied on spring to extend or compress the spring to some distance is proportion to that distance. 

Let the force be F

So, F = - K X

where K is spring constant and X is its displacement

Negative sign shows displacement of spring once it is stretched

And K is spring constant

So ,Force = ( - ) 7 × 0.3

I.e Force = - 2.1 Newton Answer

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (6, 8)

Point (5, 5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{5-8}{5-6}$
[Fraction] Subtract: $\displaystyle m=\frac{-3}{-1}$
[Fraction] Divide: $\displaystyle m=3$

The average rate of change of g(x) between x = 4 and x = 7 is 5/6 . Which statement must be true?

Blizzard [7]

Answer:

$\frac{5}{6}=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}$ would be the correct statement.

Step-by-step explanation:

As we know that

Average rate of change = Change in output / Change in input

= Δy / Δx

$=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

$=\frac{g(x_{2})-g(x_{1})}{x_{2}-x_{1}}$

$=\frac{g(7)-g(4)}{7-4}$

As the average rate of change of g(x) between x = 4 and x = 7 is 5/6.

$\:Average\:rate\:of\:change\:=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}$

$\frac{5}{6}=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}$

Therefore, $\frac{5}{6}=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}$ would be the correct statement.
