For a copper-silver alloy of composition 51 wt% Ag-49 wt% Cu and at 775˚C (1425˚F) (see Animated Figure 9.7) do the following: (

a) Determine the mass fractions of and phases. Mass fraction = [The tolerance is +/- 5.0%.] Mass fraction = [The tolerance is +/- 5.0%.] (b) Determine the mass fractions of primary and eutectic microconstituents. Mass fraction primary = [The tolerance is +/- 5.0%.] Mass fraction eutectic = [The tolerance is +/- 5.0%.] (c) Determine the mass fraction of eutectic . Mass fraction eutectic = [The tolerance is +/- 5.0%.]

And, finally, we are asked to compute the mass fraction of eutectic , We.  This quantity is simply the difference between the mass fractions of total  and primary  as

We = W – W' = 0.796 – 0.734 = 0.062

A m = 500 kg sack of coal falls vertically onto a m = 2000 kg railroad flatcar which was initially moving horizontally at 3 m/s.
vladimir2022 [97]
You can view this as an inelastic collision between a 2000 kg object moving at 3 m/s, and a stationary 500 kg object.
 The total momentum of the objects before the collision equals their momentum after collision.
 Before:
 flatcar = 2000*3 = 6000 kg*m/s. 
<span> coal = 0*500 = 0.
 After:
 flatcar & coal = 2500*V
 then
</span> 2500*V <span>= 6000,
 V = 2.4 m/s. 
</span> Additional:
 the definition of an inelastic collision is that the objects "stick together" after colliding.

Explain why blocks with the same mass do not have the same density.
Pani-rosa [81]

Answer:

Density is equal to m/v where m is mass and v is volume. Even though the blocks have the same mass, they may have different volumes and therefore they will not have the same density.

Please help me with my physics! I don not understand and please provide work.
den301095 [7]
4) B) Speed = Distance/ time
5) C) By applying second law of newton " F = ma" we say that "15 = 12 × acceleration"
15/12= acceleration
acceleration = 1.25 m/s2
6) D) It will continue to accelerate to the right but at a slower rate because of the small force (F2) being applied from the right.

Answer:

Well my good friend the other person did not give U a good answer, it is actually the third one

Explanation: well it is the most logical of all the answers if you think about it and a lot of the creatures we have in the water today are thought of to have once lived on land based on the fossils we still find to this very day my friend
