Answer:
a)5.28 Å , b)3.73 Å , c)3.048 Å
Explanation:
the atoms are situated only at the corners of cube.Each and every atom in simple cubic primitive at the corner is shared with 8 adjacent unit cells.
Therefore, a particular unit cell consist only 1/8th part of an atom.
The lattice constant of a simple cubic primitive cell is 5.28 Å
We know formula of distance,
d = 
a)(100)
a=5.28 Å
Distance = 
=5.28 Å
b)(110)
Distance = 
= 3.73 Å
c)(111)
Distance= 
= 3.048 Å
Answer:41.67kW
Explanation: a) power = force * velocity
Convert km/hr to m/s=1000m/(60×60s)
=1000/3600
P=F×vel
Power =1500×100× 1000/3600
=1500×100×5/18
=41,666.67W
=41.67kW
Answer:
yes, the recordings sound is same
Explanation:
given data
recording done = 2 performances
1st show = sold out
2nd show = lightly attended
to find out
recordings sound the same and why
solution
as per given in
- 1st show is sold out it mean in this case concert hall is full so that recording sound should be high here
- 2nd case only few people are attended and struggle for ticket and orchestra
it mean it sound performance so in both case recording sound will be same
because we do not other all are sitting at front row or they sit as they want
What the given passage is saying about the relationship between sustainability and responsibility is that;
C: We should only consider products or services to be green if their broad impact can be considered so.
<h3>Sustainability</h3>
From the passage, we see a write up questioning if the things we term to be green are truly green.
Now, from the passage, we see that a biofuel that is considered to be green is not really green if we consider that if it requires massive overproduction, it could wreck the water table.
Also, he says that if the production is local but also wasteful then it is not green.
Thus, we can see clearly that before we term a product or service as green, we should also consider their broad impact on the environment.

Answer:
The time required is 10.078 hours or 605 min
Explanation:
The formula to apply here is ;
K=(d²-d²₀ )/t
where t is time in hours
d is grain diameter to be achieved after heating in mm
d₀ is the grain diameter before heating in mm
Given
d=5.5 × 10^-2 mm
d₀=2.4 × 10^-2 mm
t₁= 500 min = 500/60 =25/3 hrs
t₂=?
n=2.2
First find K
K=(d²-d²₀ )/t₁
K={ (5.1 × 10^-2 mm)²-(2.4 × 10−2 mm)² }/ 25/3
K=(0.051²-0.024²) ÷25/2
K=0.000243 mm²/h
Re-arrange equation for K ,to get the equation for d as;
d=√(d₀²+ Kt) where now t=t₂
