Answer:
w = 706.32 [N]
Explanation:
The force due to gravitational acceleration can be calculated by means of the product of mass by gravitational acceleration.
w = m*g
where:
w = weight [N] (units of Newtons)
m = mass = 72 [kg]
g = gravity acceleration = 9.81 [m/s²]
Then we have:
![w = 72*9.81\\w = 706.32 [N]](https://tex.z-dn.net/?f=w%20%3D%2072%2A9.81%5C%5Cw%20%3D%20706.32%20%5BN%5D)
I think it’s “light energy to chemical energy” let me know if i’m wrong
Answer:
49.82414 atm
50.74675 atm
Explanation:
P = Pressure
V = Volume = 5.45 L
R = Gas constant = 0.08205 L atm/mol K
T = Temperature = 25°C
a = 0.211 atm L²/mol²
b = 0.0171 atm L²/mol²
From ideal gas law we have
The pressure is 49.82414 atm
From Van der Waals equation we have
The pressure is 50.74675 atm
Find enclosed file with a drawing and the calculations of all angles and all distances.
These are the results that you will find in it:
<span>Angle x = 90° - 22°15’
</span>
Angle y = 90° - 62°30'
Angle z = 22°15’ =
22.25°
Angle w = 62°30’ =
62.50°
tan(z) = H/a => a = H/tan(z)
tan(w) = H/b => b = H/tan(w)
a+b = 4 => H/tan(z) + H/tan(w) = 4 => H [1/tan(z) + 1/tan(x) ] =
4
<span>
</span>H = 4 / {[1/tan(z)
+ 1/tan(x) ] } = 1.35 miles
<span> </span>a
= 1.35 / tan(22.25°) = 3.30 miles
<span> </span>b = 4 – 3.30 = 0.7 miles
I hope it is very useful and you understand it. Let me know.
