3. Consider a locomotive and the rest of a freight train to be a single object. Suppose the locomotive is pulling the train up a
Nonamiya [84]

Answer:

Action - Pulling up the train.

Reaction - Friction on the locomotive

Explanation:

Locomotive is pulling the train upwards ,

Which is the action force applied by the locomotive,

As a reaction locomotive will be pulled by the train which is the reaction of pulling

Now, considering it as a action on locomotive , friction force will act on it as a reaction upwards which will result to move it upwards.

For train action is pulling up by locomotive and reaction will be friction acting on it downwards.

Estimate the volume of a typical house (2050 feet squared in size and 10 feet tall) answer in units of meters squared
Aloiza [94]

Answer:

Volume = 6248.48 m^{3}

Explanation:

Given:

The area of the house A = 2050\ ft^{2}

The height of the house h=10\ ft

We need to find the volume of a typical house.

Solution:

We find the volume of the house by multiplying the area of the house and height of the house.

Volume = Area\times height

Volume = A\times h

Area and height of the house are known, so we substitute these value in above equation.

Volume = 2050\times 10

Volume = 20500\ ft^{3}

Now we convert the unit from feet to meter.

Divide the volume by 3.2808 for m^{3}

Volume = \frac{20500}{3.2808}

Volume = 6248.48\ m^{3}

Therefore, the volume of the house is 6248.48 m^{3}

We are sending a 30 Mbit file from source host A to destination host B. All links in the path between source and destination hav
Dmitrij [34]

Answer:

t=1.5\times 10^{-4}\ s

Explanation:

Given:

  • file size to be transmitted, D=30\ Mb
  • transmission rate of data, \dot D=10\ Mb.s^{-1}
  • propagation speed, v=2\times 10^8\ m.s^{-1}
  • distance of data transfer, s=10000\ km=10^4\ m

<u>Now the delay in data transfer from source to destination for each 10 Mb:</u>

t'=\frac{s}{v}

t'=\frac{10^4}{2\times 10^8}

t'=5\times 10^{-5}\ s

<u>Now this time is taken for each 10 Mb of data transfer and we have 30 Mb to transfer:</u>

So,

t=3\times t'

t=3\times 5\times 10^{-5}

t=1.5\times 10^{-4}\ s
