Quoting from the article itself:
"Since it is above Earth's atmosphere, it gives us clearer pictures of space than telescopes on Earth can."
For a 208-volt, 4-wire, 3-phase wye power system feeds a school building, the average daily voltage is mathematically given as
x=206.23v
<h3> What is the average daily voltage of the system?</h3>
Generally, the equation for the mean is mathematically given as
x=total sum/ number
Therefore
ts=05.25 volts, 203.75 volts, 208 volts, 204.35 volts, 206.7 volts, 207 volts, and 208.55 volts.
ts=1433.6
In conclusion
x=1433.6/7
x=206.23v

Answer:
2.9 kg
Explanation:
Given that a 0.775-m3 rigid tank initially contains air whose density is 1.18 kg/m3.
According to the definition of density
Density = mass/volume
1.18 = mass / 0.775
Mass = 1.18 × 0.775
Mass = 0.9145 kg
Given that the tank is connected to a high-pressure supply line through a valve. The valve is opened, and air is allowed to enter the tank until the density in the tank rises to 4.95 kg/m3.
Using the same density formula
Density = mass/volume
4.95 = mass / 0.775
mass = 3.83625 kg
To determine the mass of air that has entered the tank, take away the mass of the air initial in the tank from the mass calculated
Mass = 3.83625 - 0.9145
Mass = 2.923kg
Therefore, the mass of air that has entered the tank is 2.9 kg approximately.
