Answer:
C) 43,2°C
Explanation:
<em>Sensible heat</em> is the amount of thermal energy that is required to change the temperature of an object, the equation for calculating the heat change is given by:
Q=msΔT
where:
- Q, heat that has been absorbed or realeased by the substance [J]
- m, mass of the substance [g]
- s, specific heat capacity [J/g°C]
- ΔT, changes in the substance temperature [°C]
To solve the problem, we clear ΔT of the equation and then replace our data:
Q=890 [J],
m=16,6 [g],
s=2,74 [J/g°C]
Q=msΔT.......................ΔT=Q/ms
Δ°C
As:
ΔT=Tfinal-Tinitial
Tfinal=ΔT+Tinitial
Tfinal=21,7+21,5=43,2°C
The final temperature of the ethanol is 43,2°C.
Answer:
a) the speed up is 1.45
b) the speed up is 1.42
Explanation:
Given
5 stage pipeline = 1 ns clock cycle
12 stage pipeline = 0.6 ns clock cycle
a) The speed up is
(eq. 1)
The CPIpipelined is
(eq. 2)
The execution time is
(eq. 3)
The CPI for 5-stage pipeline is
CPI = 6/5
cycle time = 1 s
The CPI for 12-stage pipeline is
CPI = 11/8
cycle time = 0.6 s
Replacing values in equation 1
b) The equation for CPI instruction in 5-stage is
For CPI instruction in 12-stage is
The speed up is using the equation 1
