A motorist is driving his car at 60km/hr when he observes that a traffic light 250m ahead turns red. The traffic light is
Alecsey [184]

Explanation:

Okay soo-

Given-

u = 60 km/hr = 60×1000/3600=50/3 m/s

t = 20 s

s = 250 m

a = ?

v = ?

Solution -

Here, acceleration is uniform.

(a) According to 2nd kinematics equation,

s = ut + ½at^2

250 = 50/3 ×20 + 0.5×a×20×20

250-1000/3=200a

(750-1000)/3=200a

a = -250/(3×200)

a = -5/12

a = 0.4167 m/s^2

The required uniform acceleration of the car is 0.4167 m/s^2.

(b) According to 1st kinematics equation

v = u + at

v = 50/3 + (-5/12)×20

v = 50/3-25/3

v = 25/3

v = 8.33 m/s

The speed of the car as it passes the traffic light is 8.33 m/s.

Good luck!

A thin plastic membrane is used to separate helium from a gas stream. Under steady-state conditions the concentration of helium
Juli2301 [7.4K]

Answer:

N_A=1.5*10^-8 kmol/s.m^2

Explanation:

<u>KNOWN: </u>

Molar concentration of helium at the inner and outer surfaces of a plastic membrane. Diffusion coefficient and membrane thickness.  

<u>FIND:</u>

Molar diffusion flux.  

<u>ASSUMPTIONS:</u>

(1) Steady-state conditions, (2) One-dimensional diffusion in a plane wall, (3) Stationary medium, (4) Uniform C = C_A + C_B.  

<u>ANALYSIS:</u> The molar flux may be obtained from

 N_A=D_AB/L(C_A,1-C_A,2)

       =10^-9 m^2/s/0.001 m(0.02-0.005)kmol/m^3

N_A=1.5*10^-8 kmol/s.m^2

<u>COMMENTS:</u> The mass flux is:

n_A,x=M_a*N_A,x

n_A,x=6*10^-8 kg/s m^2

A hypothetical metal alloy has a grain diameter of 1.7 ´ 10-2 mm. After a heat treatment at 450°C for 250 min the grain diameter
Yuliya22 [10]

Answer:1103 minutes/66180 seconds

Explanation:

FIRST STEP: is to FIND the value of K using the formula below;

K= d^n - d^n(o)/t .....................(1).

Parameters given from the question d^n = 4.5×10^-2 mm, d^n(o)= 1.7 × 10^-2 mm, t= 250 minutes(min) and n= 2.1.

Slotting in the parameters into the equation (1) above,then;

(4.5×10^-2)^2.1 - (1.7×10^-2)^2.1/ 250

= 5.2 × 10^-6 mm^2.1/min.

SECOND STEP: with the value of K from the second step, we can use it to calculate the required time based on the diameter. Therefore, equation (1) becomes;

t= d^2.1 - d^2.1(o)/ K

(8.7×10^-2)^2.1 - (1.7×10^-2)^2.1/ 5.2 × 10^-6

= 1,103 minutes.
