<span>The main gases within the Earth's exosphere are the lightest atmospheric gases, mainly hydrogen , with some helium, carbon dioxide, and atomic oxygen near the base of the exosphere. Since there is no clear boundary between outer space and the exosphere, the exosphere is sometimes considered a part of outer space. </span>
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 =
here D is diameter and V is volume
so
velocity =
velocity = 17 m/s
so the highest possible average flow velocity is 17 m/s

The total resistance of the resistors is R=44Ω. And the current will be I= 0.27 A.
<h3>What is the function of a resistor?</h3>
Resistors are electronic components whose main function is to limit the flow of electrical charges by converting electrical energy into thermal energy.
A)The resistances connected in series in an arm of a circuit, total resistance of that arm of is given by algebric sum individual resistances.
R = R1 + R2 + R3 = 12 + 8 + 24 = 44Ω
B) Ohm's law gives that:
V = IR
Where,
- Voltage applied to circuit (V)
- current flowing through the circuit (I)
- total resistance of the circuit (R)
(I) = V/R = 12 / 44 = 3/11 = 0.27 A
C) In series combination, all the resistances are connected one after other in a linear fashion. So, current flowing through first resistor passes to second, and then third and so on. Hence, the current flowing through all the resistance in series combination is same as the current flowing through that arm of circuit.

Answer:
i = 1.2 [amp].
Explanation:
In order to find the current in the circuit, we must perform a sum of voltages equal to zero, around the mesh.
∑V = 0
Let's take the direction of the current as shown in the drawing Clockwise.
Note: The negative sign means that the current moves in a counterclockwise direction.
