Answer:
The correct answer will be "1477.84 N".
Explanation:
Given that,
Mass,
m = 1.6 mg
or,
= 1600 kg
Initial velocity,
u = 72 km/h
=
=
Final velocity,
v = 18 km/h
=
=
Covered distance,
s = 250 m
By using the below relation, we get
⇒
On putting the values, we get
⇒
⇒ (shows the deceleration)
Slope will be given as 1 in 25, then
⇒
hence,
As we know,
⇒
or,
⇒
⇒
On substituting all the values, we get
⇒
⇒
Answer:
Explanation:
Given that
Unit cell is in FCC
Here given direction is not clear visible so we take direction [001].
We know that linear density(LD) given as
So the number of atom will be 1/2 in direction [001]
In FCC
Answer:
F(x) = 0 ; x < 0
0.064 ; 0 ≤ x < 1
0.352 ; 1 ≤ x < 2
0.784 ; 2 ≤ x < 3
1 ; x ≥ 3
Explanation:
Each wafer is classified as pass or fail.
The wafers are independent.
Then, we can modelate X : ''Number of wafers that pass the test'' as a Binomial random variable.
X ~ Bi(n,p)
Where n = 3 and p = 0.6 is the success probability
The probatility function is given by :
Where is the combinatorial number
Let's calculate f(x) :
For the cumulative distribution function that we are looking for :
The cumulative distribution function for X is :
F(x) = 0 ; x < 0
0.064 ; 0 ≤ x < 1
0.352 ; 1 ≤ x < 2
0.784 ; 2 ≤ x < 3
1 ; x ≥ 3
