Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. The law is named after 17th-century British physicist Robert Hooke. He first stated the law in 1676 as a Latin anagram.[1][2] He published the solution of his anagram in 1678[3] as: ut tensio, sic vis ("as the extension, so the force" or "the extension is proportional to the force"). Hooke states in the 1678 work that he was aware of the law since 1660.

Hooke's equation holds (to some extent) in many other situations where an elastic body is deformed, such as wind blowing on a tall building, and a musician plucking a string of a guitar. An elastic body or material for which this equation can be assumed is said to be linear-elastic or Hookean.

Hooke's law is only a first-order linear approximation to the real response of springs and other elastic bodies to applied forces. It must eventually fail once the forces exceed some limit, since no material can be compressed beyond a certain minimum size, or stretched beyond a maximum size, without some permanent deformation or change of state. Many materials will noticeably deviate from Hooke's law well before those elastic limits are reached.

On the other hand, Hooke's law is an accurate approximation for most solid bodies, as long as the forces and deformations are small enough. For this reason, Hooke's law is extensively used in all branches of science and engineering, and is the foundation of many disciplines such as seismology, molecular mechanics and acoustics. It is also the fundamental principle behind the spring scale, the manometer, and the balance wheel of the mechanical clock.

The modern theory of elasticity generalizes Hooke's law to say that the strain (deformation) of an elastic object or material is proportional to the stress applied to it. However, since general stresses and strains may have multiple independent components, the "proportionality factor" may no longer be just a single real number, but rather a linear map (a tensor) that can be represented by a matrix of real numbers.

In this general form, Hooke's law makes it possible to deduce the relation between strain and stress for complex objects in terms of intrinsic properties of the materials it is made of. For example, one can deduce that a homogeneous rod with uniform cross section will behave like a simple spring when stretched, with a stiffness k directly proportional to its cross-section area and inversely proportional to its length.

Step-by-step explanation:

2x + 15° + x = 180° { Being co-interior angles }

3x = 180°- 15°

3x = 165°

x = 165° / 3

x = 55°

2x + 15° = 2 *55° + 15° = 125°

Hope it will help :)❤

Answer:

1 7/8 or 1.875 cups

Step-by-step explanation:

This can be solved by adding the 3 fractions together

[tex]\frac{5}{8} + \frac{5}{8} + \frac{5}{8}[/tex]

[tex]\frac{5 + 5 + 5}{8}[/tex]

[tex]\frac{15}{8}[/tex] = [tex]1\frac{7}{8}[/tex]

Since the 3 cups added are the same size, this can also be solved by multiplication

5/8 x 3 = 1.875 cups = 1 7/8 cups

Answer:

197in^2

Step-by-step explanation:

5x5=25(top face)

5x5=25(left face)

9x5=45(bottom face)

6.4x5=26(right face)

Front and behind face: trapezoid area (trapezoid formula h x (a+b)/2)

(5+9)/2 x 5=7x5=35

35+35+25+25+45+25=197in^2

Answer:

m = 3/1

-11 and 13

3q+10r+2

Answer:

73.27 km/hr

Step-by-step explanation:

The fastest human sprinter sprints 100 metres in 9.58 seconds. Thus, speed of sprinter is;

V_sprinter = 100/9.8

V_sprinter = 10.204 m/s

Now, from conversion, 1 m/s = 3.6 km/hr

Then, 10.204 m/s = (10.204 × 3.6)/1 = 36.73 km/h

The cheetah sprints 110 km/hr

Thus, the cheetah is faster by: 110 - 36.73 = 73.27 km/hr

Answer: x=7

Step-by-step explanation: First, remove 3 from both sides by dividing. You will end up getting 9. Since 2x-5 = 9, add 5 from both sides by adding leaving you with 2x = 14. Divide 14 by 2 to get 7.

Answer:

Your answer is going to be answer A; (-3,2).

Answer:

A. (-3,2)

Step-by-step explanation:

C (0,0)

where,

(x,y)

Rise/run = y/x

3 units left = run -3 which is x, it's left so it's negative.

2 units up = rise 2 which is y, it's p so it's positive.

C (0,0) = (x,y) = (-3, +2)

So, C (-3,2) since it's already both at zero all you do is replace however if there is another number other than zero you just combine like terms so,

if C was (9,10) the new coordinates would be C (6,12)

Answer:

Decimal: .52

Fraction: 13/25

Step-by-step explanation:

As a Decimal, 52% would be .52  

All you have to do to get that, is to move the decimal over twice.

So as a fraction, you would put 100 as the denominator because 100 is how high a percent can get.

52/100 → 13/25

Answer:

All sides are congruent by definition. The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.

Sum of any two adjacent angles is 180°

Answer:

The null hypothesis is that the mean vitamin C, μ is equal to the sample mean μ₀

The alternative hypothesis is that the mean vitamin C, μ is not equal to the sample mean μ₀

Step-by-step explanation:

The number chewable vitamin tablets in the sample, n = 85

The mean amount of vitamin C, μ₀ = 272 milligrams

The hypothesis test is to determine the strength of the evidence that the mean mass of vitamin C per tablet differs from 270 milligrams

The null hypothesis, H₀:  μ = μ₀ =272 milligrams

The alternative hypothesis, Hₐ: μ ≠ μ₀ = 272 milligrams

Step-by-step explanation:

25 ÷ 5 = 5

5 x 10 = 50

Answer: 15

Step-by-step explanation: 5 % means 0.05

0.05 ·300 =15

the coupon is 35% off, therefore, she actually paid 65%

0.65(128.25) = 83.36 (what she paid without tax)

now we add the sales tax of 4%

83.36 (1.04) = 86.69 <== total cost
