When she starts out, he is (40x2.5)= 100 miles ahead of her.

She gains (65-40)= 25 miles on him every hour.

It takes her (100/25)= 4 hours to catch up to him.

A diffusion couple composed of two silver– gold alloys is formed; these alloys have compositions of 98 wt% Ag–2 wt% Au and 95 wt
jeyben [28]

Answer:

for this problem, 2.5 = (5+2/2)-(5-2/2)erf (50×10-6m/2Dt)

It now becomes necessary to compute the diffusion coefficient at 750°C (1023 K) given that D0= 8.5 ×10-5m2/s and Qd= 202,100 J/mol.

we have D= D0exp( -Qd/RT)

=(8.5×105m2/s)exp(-202,100/8.31×1023)

= 4.03 ×10-15m2/s

At time t = 0 a car has a velocity of 16 m/s. It slows down with an acceleration given by
Leni [432]

Answer:

B

Explanation:

We know the inital velocity is 16 m/s

Acclereation is -0.5 m/s^2

And that final velocity is 0

We need to find time

v _{f} = v _{i} + at

0 = 16 + ( - 0.5)t

- 16 =  - 0.5t

32 = t

The answer is B
