What kind of analogy is this?
A. synonyms
B. part to whole
C. degrees of intensity
<span>D. cause to effect
This is because a synonym refers to things like "normal" or  "regular" like your calling someone something.

Synonyms because all of these analogies are of words that mean the same. For example, average and regular mean basically the same thing, thus they are synonyms.

The rigid link is supported by a pin at A and two A-36 steel wires, each having an unstretched length of 12 in. and cross-sectio
Leokris [45]

Answer:

Extension of the wire is not indicated

Explanation:

Young modulus (YM)= (stress/Strain); Tensile Stress/tensile Strain

=> YM *Strain =Stress=F/A; A is cross sectional area and F is the force

(YM * Strain * A)/36 =F (Force developed in each wire)

F = (350 *e*0.0125)/12

The amount of NOx emission produced by a household is required.

The total amount of NOx the household is responsible for is 91.06 kg.

1 car produces 11 kg of NOx per year.

Natural gas burning produces 4.3 g of NOx per therm.

Electric power plant produces 7.1 g of NOx per kwh.

2 cars will produce 2\times 11=22\ \text{kg} of NOx.

1200 therms of natural gas will produce 1200\times 4.3=5160\ \text{g}

9000 kWh will produce 7.1\times 9000=63900\ \text{g}

Converting all to kg and finding the total amount

22+5.16+63.9=91.06\ \text{kg}

The total amount of NOx the household is responsible for is 91.06 kg.

A proton, moving with a velocity of vii⁄, collides elastically with another proton that is initially at rest. Assuming that the
KATRIN_1 [288]

Answer:

Explanation:

Given that,

Mass of proton

Mp=m=1.627×10^-27kg

One of the proton is at rest then it velocity is 0

Let the other proton be moving at vi

Since the after collision the two proton moves together with the same velocity(i.e inelastic collision)

Then, using conservation of energy

Kinetic energy before collision = kinetic energy after collision

Given that, K.E=½mv²

Before collision = after collision

½mvi²+½m(0)²=½(m+m)vf²

½mvi²=½(2m)vf²

½mvi²=mvf²

Divide through by m

½vi²=vf²

vi²=2vf²

Take square root of both sides

√vi²=√(2vf²).

vi=√2 ×vf

Then, the final velocity is

vf = vi /√2

b. Direction of the velocity vectors after collision

Let vf1 be the final velocity for the incident proton

vf2 be the final velocity for the proton initially at rest.

Conserving momentum in the ˆj direction

Piy = 0 = Pfy = mp•vf1y +mp•vf2y

vf1y = −vf2y

So the protons have equal magnitude speeds in the ˆj direction. Because the speed of the particles are equal, the magnitude of their speeds in the ˆi direction should also be equal |vf1x| = |vf2x|.

Conserving momentum in the ˆi direction.

Pix = mp•vi = Pfx = mp•vf1x +mp•vf2x = 2mp•vfx

Then, vfx =vi/2

Using the Pythagorean theorem to solve for the magnitude of vfy

vf²=vi²/2= vfx² +vfy² =vi²/4+vfy²

vfy = vi√(½-¼)=vi/2=vfx

So because the ˆi and ˆj components of vf are the same, both protons are deflected away at an angle of θ = 45° from the ˆi direction, with opposite ˆj components (so the angle between vf1 and vf2 is 90°).
