A spring stretches out by 8cm when a 0.2 kg weight is placed on it. How much does the spring stretch by when a 0.5 kg weight is

Ierofanga [76]

m₁ = mass hanged initially = 0.2 kg

x₁ = initial stretch in the spring = 8 cm = 0.08 m

k = spring constant of the spring

the weight of the mass hanged is balanced by the spring force by the spring hence

Spring force = weight of mass hanged

k x₁ = m₁ g

k (0.08) = (0.2) (9.8)

k = 24.5 N/m

m₂ = mass hanged later = 0.5 kg

x₂ = final stretch in the spring = ?

k = spring constant of the spring = 24.5 N/m

the weight of the mass hanged is balanced by the spring force by the spring hence

Spring force = weight of mass hanged

k x₂ = m₂ g

(24.5) x₂ = (0.5) (9.8)

x₂ = 0.2 m = 20 cm

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other. Find the length of the other piece

sergeinik [125]

Answer:

The length of the other piece is 38 inch.

Step-by-step explanation:

Given:

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.

Now, to find the length of the other piece.

Let the length of the other piece be $x$ .

And the length of one piece be $4x$ .

The total length of the pipe = $190 inch$

According to question:

$4x+x=190$

⇒ $5x=190$

<em>Dividing both sides by 5 we get:</em>

⇒ $x=38$

Therefore, the length of the other piece is 38 inch.

PLS HELP!

wolverine [178]

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

$Diagonal=\sqrt{length^2+width^2}$

$Diagonal=\sqrt{(50)^2+(55)^2}$

$Diagonal=\sqrt{2500+3025}$

$Diagonal=\sqrt{5525
}$

On further simplification, we get

$Diagonal=74.3303437$

$Diagonal\approx 74.3$

Therefore, the length of the required fencing is 74.3 yards.
