Real and erect
Explanation
Fermentation is the stage where
it is not part of the cellular respiration. The answer is letter A.
fermentation does not require oxygen to do respiration, rather, these are the
glycolysis, Kreb’s cycle and electron transport.
Answer:
4.36 seconds
Explanation:
According to the question;
- Force is 550 N
- Mass of the car is 1200 kg
- Velocity of the car is 2.0 m/s
We are needed to find the time the car must the tow track pull the car.
- From Newton's second law of motion;
- Impulsive force, F = Mv÷t , where m is the mass, v is the velocity and t is the time.
Rearranging the formula;
t = mv ÷ F
Thus;
Time = (1200 kg × 2.0 m/s²) ÷ 550 N
= 4.36 seconds
Thus, the time needed to pull the car is 4.36 seconds
Answer:
the highest possible average flow velocity is 17 m/s
Explanation:
given data
power = 60 W
pressure = 50 Pa
diameter = 30 cm = 0.3 m
to find out
Determine the highest possible average flow velocity in the duct
solution
we will apply here energy balance equation that is
energy in = energy out
power + m(Pv)1 = m (Pv)2
power = mv ( P2 -P1)
power = V ΔP
here P is pressure and V is maximum volume flow rate
put here value and find V
60 = V ( 50)
maximum volume v = 1.2 m³/s
and
maximum average velocity is
Velocity = ![\frac{V}{\frac{\pi }{4} D^2 }](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B%5Cfrac%7B%5Cpi%20%7D%7B4%7D%20D%5E2%20%7D)
here D is diameter and V is volume
so
velocity = ![\frac{1.2}{\frac{\pi }{4} 0.3^2 }](https://tex.z-dn.net/?f=%5Cfrac%7B1.2%7D%7B%5Cfrac%7B%5Cpi%20%7D%7B4%7D%200.3%5E2%20%7D)
velocity = 17 m/s
so the highest possible average flow velocity is 17 m/s
Answer:
Container A and C
Explanation:
ideal gas equation gives P=nRT/V
so at constant Temperature and pressure, P=n/T
Container A and C after dividing number of moles and Volume, are found to be the same=0.0446
