Answer:
The mechanical advantage is 3 to 1
Explanation:
A frictionless pulley with three support ropes carries equal tension on each of the ropes thus;
Tension in each pulley rope = T
Total tension in the 3 ropes = 3 × T = 3·T
Direction of the tension forces on each rope = Unidirectional
Total force provided by the 3 ropes = 3·T
Therefore, a force, T, applied at the end of the rope will result in a lifting force of 3·T
Hence, the mechanical advantage = 3·T to T which is presented as follows;
The mechanical advantage = 3 to 1.
Answer:
Q= 6491.100 kJ/s
Explanation:
Air-Fuel Ratio:
For a combustion reaction the proportion of air that is present in a gaseous substance responsible for the reaction,this proportion is known as air-fuel ratio.The air fuel ratio is calculated using the combustion reaction for the substance.
Considering reaction for the Ethanol as
C₂H₅OH +XO₂(O₂+3.76N₂)→ aCO₂+bH₂O+cN₂
Balancing the equation we get;
a=2,
2b=6
∴ b=3
xO₂=3
The air-fuel ratio
A/F = XO₂+H₂O+xN₂× mass of N₂/mass(fuel)
3.31×31.9+11.28×28.013/46.069
= 8.943
Equivalent ratio = 0.7,
so, heat transfer
Q= m ×Cp×ΔT
= 75×0.7×112.4(1500-400)
Q= 6491.100 kJ/s
1kJ/s=1000w
∴ Q= 6491100 W

Answer:
Binomial Function
I got my output using the formula = 1 - BINOMDIST (17, 50, 0.3, TRUE)
Then got the cumulative probability distribution at 17 to be 0.2178
Explanation:
To draw a normal distribution:
1. Got to '@risk' and click on 'defined distribution'
2. Select 'binomial' in function block
3. enter formula in cell formula and click okay
The use of @RISK to draw a binomial distribution of 50 trials and probability of success as 0.3 by entering formular =RISKBINOMIAL (50, 0.3).
Options: True or false
Answer:True, it will be called CRMWRONGEDLP.
Explanation:eNotes was founded in 1998 by Brad Satoris and Alexander Bloomingdale, to enable and enhance the ability of students to solve assignments as given and other home works,eNote is also used by students to prepare effectively and efficiently for examinations.
Since its launch eNote has been a great source of educational materials for students who have gained a lot in the use of its materials.
bullwhip effect is a concept in supply chain, where forcasts causes the supply chain to be inefficient, it usually starts from retailers who raise concern of high demands.
CRMWRONGEDLP, is the program that minimizes the bullwhip effects according to eNote.
(A)-The Theoretical Strength Is Higher Than The Experimental Strength.
