Hooke’s Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?

Answers

Answer:

Simple springs obey Hooke's Law. Hooke's Law states that the force on a spring is proportional to it's displacement from it's resting length:

F = -k*x

Where F is the force, x is how far the string is stretched or compressed, and k is a proportionality constant called the spring constant. The negative sign is because the spring resists stretching.

In this case, we can solve for k using the first case:

(100N) = -k * (5cm)

k = ???

And plug that answer in to find x in the second case:

(360N) = -k * x

This is a "Hooke's Law" problem: the restoring force required to compress or stretch a spring is proportional to the distance the spring is deformed. You can figure solve it by setting up a proportion equation and then using the algebraic tool of cross multiplication to solve for the unkown "stretch".

1) set up the proportion equation

100 = 360

5 x

2) cross multiply to get a linear equation

100x = 5*360

3) solve for x

100x = 1800

x = 18

Answer:

The law: F=kx

Therefore,

180N = k * 5cm

k = 180÷5= 36N per cm

Using the known constant with the law,

270=36*x

x= 270 ÷ 36 = 7.5cm

Ok so first, we know just by looking that QT is 180° since it’s a fraught angle. If you subtract angle QRS from QT, you’ll get the value for angle SRT. 180-162 is 18 so SRT IS 18°. The other angle of the triangle is already given to us as 130°. Since all three angles of a triangle add up to 180°, we can subtract the two angles to get the remaining one. 180-130-18 is 32 so the missing angle is 32°
Hope this helped :)

Answer:

Step-by-step explanation:

Hi there!

∠SRQ = 162°

∠STR = 130°

∠RST = ?

Now;

∠SRQ = ∠RST+∠STR [external angle is equal to the sum of opposite interior angles of triangle]

∠RST = ∠SRQ-∠STR

∠RST = 162°-130°

Therefore, the measure of ∠RST is 32°.

8. Negative three times the sum of a number and two is fifteen

Answers

Answer:

-3(n + 2)= 15

Step-by-step explanation:

Based on this question, we know that the equation involves multiplication. Here we start our equation with -3!

Then it says "times the sum of a number and two" So let's just say the "number" is "n". The word "sum" means the answer to an addition problem, thus we know that we are adding "n" and 2. Let's put that in parenthesis!

-3(n+2)

And it says "is fifteen" which also means "equals to fifteen"

Therefore, the answer is:

-3(n + 2) = 15

22. Write the word sentence as an equation. The product of negative 2 and 5 plus a number d = 14.

also please solve and "product" means multiply.

Answers

The equation is:
-2 * 5 + d = 14

Solving by multiplying -2 and 5 first:
-10 + d = 14

Add 10 to both sides to get rid of the negative 10:
-10 + d + 10 = 14 + 10

-10 plus 10 gives 0 and it cancels out so:
d = 24 is the solution.

Select two statements from paragraphs 811 that best demonstrate how the author uses rhetoricto help readers better understand the relationship between Einstein's theory and Alcubierre'sdiscovery8 Wait a minute-warp theory? Just when did warp change from an imaginary.technology to an actual theory studied by real-life scientists? The answer is 1994, whenMiguel Alcubierre, a college physics student at the time, worked out the math.9 To understand Alcubierre's discovery, we need to talk a little more about AlbertEinstein After publishing his theory of special relativity in 1905, Einstein moved to a biggertheory: general relativity. Built on a set of "field equations"-formulas describing spaceand time that can have different solutions, depending how you use them-generalrelativity showed that space is like a fabric that's warped by gravity.10 Solving the Einstein field equations in his own way, Alcubierre found that a tiny.area of space in front of a ship could be compressed, while an area of space behindthe ship is expanded. This would generate a "warp bubble" that could move faster thanlight, carrying the ship inside like an ocean wave carries a surfer. Imagine that the wavecarrying the surfboard did not come from the wind, but instead were generated by anengine on the surfboard itself, and you'll understand the concept of warp drive11 Concepts are great, but can we learn to actually squeeze and stretch space like theSpandex of our workout pants?
