I’ll put you as brainiest

Nikitich [7]

<h2>Answer:38.33 Kg</h2>

Step-by-step explanation:

If $mKg$ of mass is placed on spring with spring constant $k$ ,

$mg=kx$

where $g$ is universal gravitational constant

$x$ is the displacement in the spring.

In case 1:

$25g=k(0.15)\\k=\frac{25g}{0.15}$

In case 2:

$mg=k(0.23)$

Using result from case 1,

$mg=\frac{25g}{0.15}\times 0.23$

$m=$ $38.33Kg$

Enter the patriot equivalent to Tan (A) <br><br> And<br><br> Enter the ratio equivalent to cos (B)

PolarNik [594]

Answer:

$(a)\ \tan A = \frac{5}{12}$

$(b)\ \cos B = \frac{5}{13}$

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

$\tan(A)$

The tan of an angle is:

$\tan(\theta) = \frac{Opposite}{Adjacent}$

From the given triangle.

$Opposite = 5$

$Adjacent = 12$

So, we have:

$\tan A = \frac{5}{12}$

Solving (b)

$\cos(B)$

The cos of an angle is:

$\cos(\theta) = \frac{Adjacent}{Hypotenuse}$

From the given triangle.

$Adjacent = 5$

$Hypotenuse = 13$

So, we have:

$\cos B = \frac{5}{13}$
