Answer:
hypoeutectoid
Explanation:
ferrite: pure form of iron
cementite: It is iron carbide with 93.3% iron and 6.67% carbon
hypoeutectoid: Eutectoid steel with carbon fraction less than 0.8%
hypereutectoid: Eutectoid Steel with carbon content more than 0.8%
For the mentioned iron-carbide alloy,
% of carbon in iron-carbide alloy= percentage of cementite × percentage of carbon in cementite
% of carbon in iron-carbide alloy= 0.09× 0.0667
= 0.6%
so the alloy is hypoeutectoid
Answer:
Option (B) increases only
Explanation:
An isolated system, in thermodynamics is defined as the system which does not allow the exchange of both the energy and mass in between the system and the surrounding.
In any practical thermodynamic process, the entropy of an isolated system increases only as the system can neither exchange energy nor mass but can generate the randomness in the molecules inside the system thus increasing its entropy up to the equilibrium point at which it reaches its maximum point.
Answer:
An emergency kit
Explanation:
The reason I say this is because:
A first aid kit can aid you if you have..
Scars
Cuts
Bruises
So, i would say that The first aid kit is the life line.
Answer:
Attached is the logic diagram.
Explanation:
Motion Sensors S1 S1 S3 S4
Master switch M
Siren Enable Switch A
Light Enable Switch L
Phone Call Enable Switch P
Buzzing Siren B
Flashing Light F
Call Box C
The logic operates as follows, when ANY of the sensors goes active (1), the output must be active, so for the sensors inputs we use an OR gate. After that the OR signal output goes to the switches AND gates, if any of the switches is off, the outputs are going to be LOW or (0)
Answer:
a)
b)
Explanation:
Previous concepts
The cumulative distribution function (CDF) F(x),"describes the probability that a random variableX with a given probability distribution will be found at a value less than or equal to x".
The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution".
Part a
Let X the random variable of interest. We know on this case that
And we know the probability denisty function for x given by:
In order to find the cdf we need to do the following integral:
Part b
Assuming that , then the density function is given by:
And for this case we want this probability:
And evaluating the integral we got:
