Answer:
True
Explanation:
CLASSIFICATION OF CERAMICS: ceramics can be classified in mainly three categories
- oxides : ceria, zirconia
- non oxide: carbide nitride
- composite materials : combination of oxides and non oxides
PROPERTIES OF CERAMICS :
- High melting point
- high hardness
- great strength
- Low electrical and thermal conductivity( good insulator)
- they are very less reactive with others
- its products are very hard
Answer:
D. Rectangular
Explanation:
This is because rectangular coordinate systems are used in plotting common straight lines graphs with the formulae,
Y = Mx + c
Where y is the vertical coordinate
X is the horizontal coordinate
M is the dlope of the line
C is the y-axis intercept
Answer:
fracture will occur as the value is less than E/10 (= 22.5)
Explanation:
If the maximum strength at tip Is greater than theoretical fracture strength value then fracture will occur and if the maximum strength is lower than theoretical fracture strength then no fracture will occur.
= 15 GPa
fracture will occur as the value is less than E/10 = 22.5
Answer:
i) 125 * 10^9 i
ii) 5.2 ns
iii) 4.8 ns
Explanation:
i) The throughput of the processor for an unpipelined processor
= = 125 * 10^9 instructions per set
ii ) for a 10-stage pipeline
1st instruction :
= 0.2 + 8ns/10
= 0.2 + 0.8 = 1ns
2nd instruction
= 0.2 + 1 + 4
= 5.2 ns
iii). for a 20-stage pipeline
1st instruction
= 0.2 + 8ns/20
= 0.2 + 0.4 = 0.6 ns
2nd instruction
= 0.2 + 0.6 + 4
= 4.8 ns
Answer: Nuclear Waste
Explanation: Nuclear energy makes radioactive waste. This radioactive waste is very deadly to all life forms.
Hope this helps!
