Answer:
C = 0.22857 ng / m³
Explanation:
Let's solve this problem for part the total time in the kitchen is
t = 2h (60 min / 1h) = 120 min
The concentration (C) quantity of benzol pyrene is the initial quantity plus the quantity generated per area minus the quantity eliminated by the air flow. The amount removed can be calculated assuming that an amount of extra air that must be filled with the pollutant
amount generated
C = co + time_generation rate / (area_house + area_flow)
C = 0.2 + 0.01 120 / (40+ 2)
C = 0.22857 ng / m³
Answer:
<em>D. Determine saving or debt</em>
Explanation:
Acceleration of Car = 10 ms⁻²
Explanation:
Step 1:
The basic formula of acceleration is a = (v-u)/t ms⁻²
where, v- final velocity
u- initial velocity
t= time taken
Step 2:
Here v = 70 ms⁻¹
u = 50 ms⁻¹
t = 5 s
∴ a = ( 70 - 20)/5
a = 10 ms⁻²
Answer:
Explanation:
it is observed given the information by the y subunit of ATP synthase that when one variable is changed, F1 motor becomes reversible and this is achieved by having the subunit as the reversible motor.
