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:
Explanation: Peak – the highest point above the rest position. Trough – the lowest point below the rest position. Amplitude – the maximum displacement of a point of a wave from its rest position. Wavelength – distance covered by a full cycle of the wave. Usually measured from peak to peak, or trough to trough.

Answer:
4
Explanation:
A "board foot" is 1/12 of a cubic foot. It is the volume of a board 1" thick and 1 foot square.
Here, the board is 1" thick, so the number of board feet is numerically equal to the number of square feet of area it has.
(1/2 ft)(8 ft) = 4 ft²
The number of board feet is 4.
Answer:
d)0.991lbf
Explanation:
the property known as specific gravity is the relationship between the density of the fluid and the density of the water, so to find the density of the rock we must multiply the specific gravity by the density of the water = 1000kg / m ^ 3, when we have the density we must multiply it by volume and gravity to find the weight.
W=2.5ρVg
ρ=Density of water=1000kg / m ^ 3
V=0.00018 m^3
g=9.81m/s^2
W=(2.5)(1000)(0.00018)(9.81)
W=4.41N=0.991lbf
Answer:
name(x) <- c("New York", "Seattle", "Los Angeles")
Explanation:
Lists can also have names, which is often very useful.
