Muscles are attached to bones; they help us walk and run and smile. All the bones in our body make up our skeleton from the top of our skull to the tips of the phalanges at the end of our toes. Muscles stretch across our bones and are attached with tendons.

Answer:

They are different because....

Explanation:

Muscles: produce heat for the body to sustain temperature, helps with balance, posture and muscle tone - partial contraction of muscles taking turns to hold the neck up for example. 3 types of muscle, being; cardiac (found in the heart as a thick, branched arrangement of muscle cells), skeletal (the ones you can flex and aid movement) and smooth (found in the uterus and alimentary canal, aiding internal movement). So the main purpose is movement, heat and balance.

Bones: leverage movement, protect vital internal organs, provide a framework for the body, produce red blood cells from red bone marrow, store minerals and fat in yellow bone marrow, in the middle of the bone, known as the diaphysis. The last one is also that they allow our joints to connect provide a foundation for tendons to attach to. There are also many types of joints, but that’s for another time.

Hope this helps :)

In a wave, what do you call the difference from crest to crest or trough to trough
UNO [17]
The correct answer is "wavelength".

In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is 
D) wavelength.

A vector has an x component of -27.5 units and a y component of 41.4 units. Find the magnitude and direction of this vector. mag
evablogger [386]

Answer:

a.) magnitude __49.7__ unit(s)

b.) direction __123.6°_  counterclockwise from the +x axis

Explanation:

Let Vector is v

x-component of Vector v = x = -27.5 units   (minus sign indicate that x-component is along the minus x-axis )

y-component of Vector v = y = 41.4 units

Magnitude of v = ?

Direction of v = ?

To find the magnitude of the vector

                                     v =\sqrt{x^{2}+y^{2}  }  

                                     v = \sqrt{-27.5^{2}+41.4^{2} }

                                     v = 49.7 units  

To find direction

                                 θ = tan⁻¹(y/x)

                                 θ = tan⁻¹(41.4/-27.5)

                                 θ = -56.4°

This Angle is in the clockwise direction with respect to -x axis.

We need to find Angle counterclockwise from the +x axis.

So,

                                 θ = 180° - 56.4°

                                 θ = 123.6°                

The given vector is in 2nd quadrant

Calculate the pressure exerted by 11.1 moles of neon gas in a volume of 5.45 L at 25°C using (a) the ideal gas equation and (b)
Ilia_Sergeevich [38]

Answer:

49.82414 atm

50.74675 atm

Explanation:

P = Pressure

V = Volume = 5.45 L

R = Gas constant = 0.08205 L atm/mol K

T = Temperature = 25°C

a = 0.211 atm L²/mol²

b = 0.0171 atm L²/mol²

From ideal gas law we have

PV=nRT\\\Rightarrow P=\dfrac{nRT}{V}\\\Rightarrow P=\dfrac{11.1\times 0.08205(273.15+25)}{5.45}\\\Rightarrow P=49.82414\ atm

The pressure is 49.82414 atm

From Van der Waals equation we have

\left(P+\frac{an^2}{V^2}\right)\left(v-nb\right)=nRT\\\Rightarrow P=\dfrac{nRT}{V-nb}-\dfrac{an^2}{V^2}\\\Rightarrow P=\dfrac{11.1\times 0.08205\times (273.15+25)}{5.45-(11.1\times 0.0171)}-\dfrac{0.211\times 11.1^2}{5.45^2}\\\Rightarrow P=50.74675\ atm

The pressure is 50.74675 atm
