A. The  primary benefit of this process is each failed design provides more information for the next design.

<h3>What is design process for technology?</h3>

Design process for technology are the steps used to obtain a desired technological results.

Technological design process include:

  • identify a problem,
  • research the problem,
  • generate possible solutions,
  • select the best solution, create a model,
  • test the model,
  • refine and retest the model as needed,
  • communicate the final solution.

During technological design process, a failed result can provide a greater insights for the next step necessary for the end goal.

Thus, the  primary benefit of this process is each failed design provides more information for the next design.

EJ is taking his little sister, Ebony, on her first carousel ride. His mass is 75.0 kg, and her mass is 10.0 kg. They ride the s
almond37 [142]

You have to find interia using I=mr^2.  

m=75+10  

radius = 11  

Then you have to substitute in first formula above to find the angular speed.

14020=(75+10)x v x 11  

v= 14020/ (85x11) = 15m/s

To find linear speed, use V=wr.

Equation: V = 11*1.363 = 15m/s = 33.6mi/hr

Hope this helps! :)

A 1000 kg train car traveling at 12 m/s on a level track has 400 kg of sand dumped, vertically, into it. What is the final speed
crimeas [40]

Answer:

The final speed of the train car is 8.57 m/s.

Explanation:

Given that,

Mass of train car = 1000 kg

Mass of sand = 400 kg

Speed of train car = 12 m/s

We need to calculate the final speed of the train car after the sand is dumped

Using conservation of momentum

m_{1}u_{1}=(m_{1}+m_{2})v...(I)

Put the value in the equation (I)

1000\times12=(1000+400)v

v=\dfrac{1000\times12}{1400}

v=8.57\ m/s

Hence, The final speed of the train car is 8.57 m/s.

A 1.2-kg mass is projected from ground level with a velocity of 30 m/s at some unknown angle above the horizontal. A short time
Dmitriy789 [7]

Answer:

K_f = 351.84 J

Explanation:

Using the conservation of energy K:

E_i = E_f

so:

\frac{1}{2}mv^2 = K_f + mgh

where m is the mass, v the initial velocity, K_f is the kinetic energy of the mass as it clears the fence, g the gravity and h the altitude.

Then, replacing values, we get:

\frac{1}{2}(1.2kg)(30m/s)^2 = K_f + (1.2kg)(9.8m/s^2)(16m)

solving for K_f:

K_f = 351.84 J

Astronomers observe two separate solar systems each consisting of a planet orbiting a sun. The two orbits are circular and have
Oxana [17]

Answer:

(D) 3

Explanation:

The angular momentum is given by:

\vec{L}=\vec{r}\ X \ \vec{p}

Thus, the magnitude of the angular momenta of both solar systems are given by:

L_1=Rm_1v_1=Rm_1(\omega R)=R^2m_1(\frac{2\pi}{T_1})=2\pi R^2\frac{m_1}{T_1}\\\\L_2=Rm_2v_2=2\pi R^2\frac{m_2}{T_2}

where we have taken that both systems has the same radius.

By taking into account that T1=3T2, we have

L_1=2\pi R^2\frac{m_1}{3T_2}=\frac{1}{3}2\pi R^2\frac{1}{T_2}m_1=\frac{1}{3}\frac{L_2}{m_2}m_1

but L1=L2=L:

L=\frac{1}{3}L\frac{m_1}{m_2}\\\\\frac{m_1}{m_2}=3

Hence, the answer is (D) 3
