Answer:

Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up.

Explanation:

Hope this helps! Good Luck on the rest of your assignments! :)

Answer:

Distance is quite literally the total amount of distance you have covered. Displacement is the total displacement from your origin. For example, if you were to move 5m north then 2m south, your total displacement from your origin would be 3m north.

Suppose a vertebra is subjected to a shearing force of 420 N. Find the shear deformation in m, taking the vertebra to be a cylin

vazorg [7]

Answer:

$1.34103\times 10^{-7}\ m$

Explanation:

F = Shearing force = 420 N

$L_0$ = Initial length = 2.6 cm

d = Diameter = 3.6 cm

r = Radius = $\frac{d}{2}=\frac{3.6}{2}=1.8\ cm$

E = Young's modulus = $80\times 10^9\ N/m^2$

A = Area = $\pi r^2$

Change in length is given by

$\Delta L=\frac{FL_0}{AE}\\\Rightarrow \\\Rightarrow \Delta L=\frac{420\times 0.026}{\pi 0.018^2\times 80\times 10^9}\\\Rightarrow \Delta L=1.34103\times 10^{-7}\ m$

The shear deformation of the vertebra is $1.34103\times 10^{-7}\ m$

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 22oC and exits at 2.0

KonstantinChe [14]

Answer:

The the quality of the refrigerant at the exit of the expansion valve is 0.179.

Explanation:

Given that,

Initial pressure = 10 bar

Temperature = 22°C

Final pressure = 2.0 bar

We using the value of h

$h = 293.4\ kJ/kg$

The refrigerant during expansion undergoes a throttling process

Therefore, $h_{1}=h_{2}$

We need to calculate the quality of the refrigerant at the exit of the expansion valve

At 2.0 bar,

The property of ammonia

$h_{f}=47.8 kJ/kg$

$h_{g}=1417.7 kJ/kg$

Using formula

$h_{2}=h_{f}+x(h_{g}-h_{f})$

Put the value into the formula

$293.4 =47.8+x(1417.7-47.8)$

$x=\dfrac{293.4-47.8}{1417.7-47.8}$

$x=0.179$

Hence, The the quality of the refrigerant at the exit of the expansion valve is 0.179.

Water flows over a section of niagara falls at the rate of 1.2x10^6 and falls 50.0 m. how much power is generated by the falling

iren [92.7K]

The solution for this is:

Power = Energy transferred / Time taken

Energy Transferred in one second ( Power) = mgh/s

= (1.2x10^6)(9.8)(50) = 588000000 J/s

Power = 588000000 W

Power is work done / time

Work done in one second = [ rate of fall of mass]

gh = 1.2* *9.81*50 x 10^6 J/s

= 5.886e+8 W
