Max (mass = 15 kg) is hanging from one end of a 13-m long bungee cord that has its other end fixed to a bridge above. The bungee cord has a circular cross section with a diameter of 2. 5 cm, and a young’s modulus of 17 mpa. What is the stress in the bungee cord due to max’s weight?

Answers

Answer 1

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.

How to find the stress experimented by the bungee cord

Let suppose that the stress ([tex]\sigma[/tex]), in pascals, experimented by the bungee cord is entirely elastic and uniform. By Newton's Laws we know that the tension ([tex]T[/tex]), in newtons, experimented by the cord equals Max's weight. The stress on the bungee cord is axial and is described by following formula:

[tex]\sigma = \frac{m\cdot g}{\frac{\pi\cdot D^{2}}{4} }[/tex]   (1)

Where:

[tex]m[/tex] - Max's mass, in kilograms[tex]g[/tex] - Gravitational acceleration, in meters per square second[tex]D[/tex] - Diameter of the circular cross section, in meters

If we know that [tex]m = 15\,kg[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] and [tex]D = 0.025\,m[/tex], then the stress experimented by the bungee cord is:

[tex]\sigma = \frac{(15\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}{\frac{\pi}{4}\cdot (0.025\,m)^{2} }[/tex]

[tex]\sigma \approx 299679.845\,Pa\, (299.680\,kPa)[/tex]

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals. [tex]\blacksquare[/tex]

This theory of emotion suggests that first a specific physiological response to stimuli is experienced, and the emotion that results is an interpretation of this unique physiological "code"

Answers

James–Lange theory is a physiological theory of emotion that explains that emotions are created in response to experiences and stimuli, where the autonomic nervous system creates physiological responses.

What is James–Lange theory?

It is a theory proposed independently by William James and Carl Lange, which suggests that emotions occur as a consequence of physiological reactions to events.

For this theory, emotions are processes that involve a series of triggering conditions or relevant stimuli.

Therefore, we can conclude that the James–Lange theory explains the origin of the components of emotion and where physiological activation plays an important role in the existence of an emotional response.

A spring gun shoots out a plastic ball at speed v0. The spring is then compressed twice the distance it was on the first shot

Answers

Based on the compression of the spring and the speed, the following are true:

The factor by which the spring's potential energy is increased is = 4.The factor of increase in speed = 2.

What is the factor of increase in potential energy?

Potential energy is found as:

= 0.5k x (2 x compression²)

= 4 x 1/2kx²

The 4 shows that the potential energy increases by 4 times.

What is the factor of increase in speed?

Initial speed is:

= x × √(k/m)

New speed will be:

= Compression factor x speed

= 2x × √(k/m)

The speed will therefore be increased by a factor of 2.

What is Public policy?

Governmental bodies create laws, set policies, and distribute funds in every society. A system of rules, regulations, courses of action, and financial priorities involving a specific subject that have been established by a governmental body or its representatives is known as public policy.

People and organizations frequently make an effort to influence public policy through advocacy, education, or the mobilization of interest groups.

In Western-style democracies, public policy is clearly shaped differently from how it is in other systems of government. But it is logical to suppose that competing interest groups would always make an effort to sway policymakers in their direction.

Energy is neither created nor destroyed rather it is transformed/converted from one form to another. when the cat is at rest on the tree it possesses a potential energy but at it falls to the ground the potential energy is converted to a kinetic energy. Also

As the cat consumes the rat the energy absorbed from the consumption of the rat is converted to mechanical energy which enables the mobility of the rat.

M₁ = 0.30 M

V₁ = 12.5 ml

M₂ =  (unknown)

V₂ = 285


0.30 x 12.5 = 285 M₂

M₂ = 3.8/ 285

Charlie earns an annual salary of $61,870. If he is paid weekly, how much would his gross pay be each week?

Answers

In a year, there are total 52 weeks usually, so annual salary is weekly salary times 52. Charles' weekly pay is given by: Option d: $1,189.81

How to count the number of ways in a year?

A year contains approx 365 days usually (leaving leap years)

A week contains 7 days.

Dividing 365 in group of 7s, we get:

(1 as remainder, 52 as quotient), so one day is left only) (this is not always the case that there would be 52 weeks only, there can be sometimes 51 weeks due to some incomplete weeks).

(for general case, we will assume there are 52 weeks in an year).

For the considered case, it is specified that:

Annual salary of Charles = $61,870

There are 52 weeks in an year, so, dividing his salary in 52 parts, we get his weekly salary as:

Thus,  Charles' weekly pay is given by: Option d: $1,189.81
