Answer:
The mitochondria's job is to produce the majority of the chemical energy required to power a cell's metabolic reactions.
The chloroplast's job is to create food for a cell through the process of photosynthesis.
Answer:
222.5 Gpa
Explanation:
From definition of engineering stress, ![\sigma=\frac {F}{A}](https://tex.z-dn.net/?f=%5Csigma%3D%5Cfrac%20%7BF%7D%7BA%7D)
where F is applied force and A is original area
Also, engineering strain,
where l is original area and
is elongation
We also know that Hooke's law states that ![E=\frac {\sigma}{\epsilon}=\frac {\frac {F}{A}}{\frac {\triangle l}{l}}=\frac {Fl}{A\triangle l}](https://tex.z-dn.net/?f=E%3D%5Cfrac%20%7B%5Csigma%7D%7B%5Cepsilon%7D%3D%5Cfrac%20%7B%5Cfrac%20%7BF%7D%7BA%7D%7D%7B%5Cfrac%20%7B%5Ctriangle%20l%7D%7Bl%7D%7D%3D%5Cfrac%20%7BFl%7D%7BA%5Ctriangle%20l%7D)
Since A=20 mm* 20 mm= 0.02 m*0.02 m
F= 89000 N
l= 100 mm= 0.1 m
![\triangle l= 0.1 mm= 0.1\times 10^{-3} m](https://tex.z-dn.net/?f=%5Ctriangle%20l%3D%200.1%20mm%3D%200.1%5Ctimes%2010%5E%7B-3%7D%20m)
By substitution we obtain
![E=\frac {89000\times 0.1}{0.02^{2}\times 0.1\times 10^{-3}}=2.225\times 10^{11}= 225.5 Gpa](https://tex.z-dn.net/?f=E%3D%5Cfrac%20%7B89000%5Ctimes%200.1%7D%7B0.02%5E%7B2%7D%5Ctimes%200.1%5Ctimes%2010%5E%7B-3%7D%7D%3D2.225%5Ctimes%2010%5E%7B11%7D%3D%20225.5%20Gpa)
Answer:
b. Technician B only
Explanation:
A watchdog timer is a circuit that automatically monitors the MCU (Microcontroller Unit) for any anomaly, detects it and helps the MCU to recover from the malfunction it has detected.
If the input signal turn-on time is too fast for the input circuit, that is a malfunction and this activates the watchdog timer circuit to correct this malfunction immediately. So Technician B only is correct as the watchdog timer is activated immediately once there is a malfunction.
Answer:
The correct answer is: the following factors are needed to properly consider while selecting a brake or clutch:
-Engagement
-Friction
-Electromagnetic
-Mechanical
-Actuation
-Electric
-Fluid power
-Self-actuation
-Key concepts
-Application notes
-Selection criteria
Explanation:
Clutches and brakes are important devices in many rotating drive systems, it is very important to guarantee the security and the proper function of them accomplishing a high quality parameters in those factors.
Answer:
1.0MG
Explanation:
to solve this problem we use this formula
S₀-S/t = ksx --- (1)
the values have been given as
concentration = S₀ = 250mg
effluent concentration = S= 10mg
value of K = 0.04L/day
x = 3000 mg
when we put these values into this equation,
250-10/t = 0.04x10x3000
240/t = 1200
we cross multiply from this stage
240 = 1200t
t = 240/1200
t = 0.2
remember the question says that 5MGD is required to be treated
so the volume would be
v = 0.2x5
= 1.0 MG
