Answer:
Explanation:
From the given information:
Let the weight of the mix in the air be =
Let the weight of the mix in water be = ; &
the bulk specific gravity be =
SO;
Also;
From (2), make the subject:
Now, equation (1) can be rewritten as:
Replacing the values;
Answer:
Rf=470 ohms R1=10ohms, Schmatic is attached
Explanation:
For non-inverting amplifiers
Gain= 1+(Rf/R1)
480=1+(Rf/R1)
470=Rf/R1
if Rf=470Ω and R1=10Ω
then,
47=47

Answer:
(d) Spheroidizing
Explanation:
Spheroidizing
This is the heat treatment process for steel which having carbon percentage more than 0.8 %.As we know that a hard and brittle material is having carbon percentage more than 0.8 %.That is why this process is suitable for the hard materials.
In this process a hard and brittle materials convert into soft and ductile after this it improve the machine ability as well as improve the tool life.
In this process grain become spheroidal and these grains are ductile.
Answer:
no of unit is 17941
Explanation:
given data
fixed cost = $338,000
variable cost = $143 per unit
fixed cost = $1,244,000
variable cost = $92.50 per unit
solution
we consider here no of unit is = n
so here total cost of labor will be sum of fix and variable cost i.e
total cost of labor = $33800 + $143 n ..........1
and
total cost of capital intensive = $1,244,000 + $92.5 n ..........2
so here in both we prefer cost of capital if cost of capital intensive less than cost of labor
$1,244,000 + $92.5 n < $33800 + $143 n
solve we get
n >
n > 17941
and
cost of producing less than selling cost so here
$1,244,000 + $92.5 n < 197 n
solve it we get
n >
n > 11904
so in both we get greatest no is 17941
so no of unit is 17941
