I'm not sure if I am  answering this right but all humans are made up of atoms and molecules. We are humans because we show all eight characteristics of life. I forget most of them, but that is why we are humans.

1.) Reproduce
2.) Respond to stimulize
3.) Exchange gases

I don't remember the rest.

Humans, unlike most animals (except the gorilla, monkey, etc.) have opposable thumbs. A lot of animals don't have that characteristic. Since, humans have five fingers, they can do a lot of things like holding and building stuff. That's how we naturally survive. It is what makes us different from most animals. Also, humans walk on two legs and don't really have any natural feature that could protect them from harm ( like claws, sharp teeth, venom).

You pull on a spring whose spring constant is 22 N/m, and stretch it from its equilibrium length of 0.3 m to a length of 0.7 m.
Liono4ka [1.6K]

Answer:

W= 4.4 J

Explanation

Elastic potential energy theory

If we have a spring of constant K to which a force F that produces a Δx deformation is applied, we apply Hooke's law:

F=K*x  Formula (1): The force F applied to the spring is proportional to the deformation x of the spring.

As the force is variable to calculate the work we define an average force

F_{a} =\frac{F_{f}+F_{i}  }{2}  Formula (2)

Ff: final force

Fi: initial force

The work done on the spring is :

W = Fa*Δx

Fa : average force

Δx :  displacement

W = F_{a} (x_{f} -x_{i} )   :Formula (3)

x_{f} :  final deformation

x_{i}  :initial deformation

Problem development

We calculate Ff and Fi , applying formula (1) :

F_{f} = K*x_{f} =22\frac{N}{m} *0.7m =15.4N

F_{i} = K*x_{i} =22\frac{N}{m} *0.3m =6.6N

We calculate average force applying formula (2):

F_{a} =\frac{15.4N+6.2N}{2} = 11 N

We calculate the work done on the spring  applying formula (3) :         :

W= 11N*(0.7m-0.3m) = 11N*0.4m=4.4 N*m = 4.4 Joule = 4.4 J

Work done in stages

Work is the change of elastic potential energy (ΔEp)

W=ΔEp

ΔEp= Epf-Epi

Epf= final potential energy

Epi=initial potential energy

E_{pf} =\frac{1}{2} *k*x_{f}^{2}

E_{pi} =\frac{1}{2} *k*x_{i}^{2}

E_{pf} =\frac{1}{2} *22*0.7^{2} = 5.39 J

E_{pf} =\frac{1}{2} *22*0.3^{2} = 0.99 J

W=ΔEp=  5.39 J-0.99 J = 4.4J

The area of an equilaterla triangle is increasing at a rate of 5 m^2/hr. find the rate at witch the height is chganging when the
Lena [83]

The rate at which the height is changing is ( 5 / x ) m / hr

We know that,

Area of an equilateral triangle A = \sqrt{3} x^{2} / 4

h = \sqrt{3} x / 2

Where,

x = Side

h = Height

Given that,

dA / dt = 5 m^{2} / hr

h = \sqrt{3} x / 2

Differentiate both sides with respect to t

dh / dt = ( \sqrt{3}  / 2 ) ( dx / dt )

dx / dt = ( 2 /  \sqrt{3} ) ( dh / dt )

A = \sqrt{3} x^{2} / 4

Differentiate both sides with respect to t

dA / dt = ( \sqrt{3} / 4 ) ( 2x ) ( dx / dt )

5 =  ( \sqrt{3} / 4 ) ( 2x ) ( 2 /  \sqrt{3} ) ( dh / dt )

dh / dt = ( 5 / x ) m / hr

Rate of change of height is defined as the rate at which height of an object changes with respect to time. It is represented as dh / dt

Therefore, the rate at which the height is changing is ( 5 / x ) m / hr
