Answer:
2.5m/s^2
Explanation:
Step one:
given
distance = 20meters
time = 2 seconds
initial velocity u= 0m/s
let us solve for the final velocity
velocity = distance/time
velocity= 20/2
velocity= 10m/s
divide both sides by 40

Answer:
v = 12.4 [m/s]
Explanation:
With the speed and Area information, we can determine the volumetric flow.
where:
r = radius = 0.0120 [m]
v = 2.88 [m/s]
Therefore the flow is:
Despite the fact that you cover the inlet with the finger, the volumetric flow rate is the same.
Answer :
(a). The final temperature of the gas in the cylinder A is 320 K.
(b). The final temperature of the gas in the cylinder B is 233.7 K.
(c). The final volume of the gas in the cylinder A is
(d). The final volume of the gas in the cylinder B is
Explanation :
Given that,
Number of mole n = 0.30 mol
Initial temperature = 320 K
Pressure = 3.0 atm
Final pressure = 1.0 atm
We need to calculate the initial volume
Using formula of ideal gas
Put the value into the formula
(a). We need to calculate the final temperature of the gas in the cylinder A
Using formula of ideal gas
In isothermally, the temperature is not change.
So, the final temperature of the gas in the cylinder A is 320 K.
(b). We need to calculate the final temperature of the gas in the cylinder B
Using formula of ideal gas
Put the value into the formula
(c). We need to calculate the final volume of the gas in the cylinder A
Using formula of volume of the gas
Put the value into the formula
(d). We need to calculate the final volume of the gas in the cylinder B
Using formula of volume of the gas
Hence, (a). The final temperature of the gas in the cylinder A is 320 K.
(b). The final temperature of the gas in the cylinder B is 233.7 K.
(c). The final volume of the gas in the cylinder A is
(d). The final volume of the gas in the cylinder B is
