Answer:
older plates that are subducting almost perpendicularly, and when the location is far away from the edge of other tectonic plates, are the most likely areas for copper deposits to form

Answer:
Part 1
Part 2
Explanation:
Given that
Diameter,d=1 μm
Length ,l=2 μm
As we know that volume of cylinder given as
Surface area,A
A=π d l
Part 1
Part 2
You use your shoulder muscles aka the deltiods of the muscle which plays a huge part in the rotation of your arm
you also use your triseps
also, latissimus dorsi
abdominals
and your quadriceps
Answer:
t = 250 s = 4.167 s
Explanation:
Carro A
x = x₀+v*t
⇒ x = 0 + 20*t
⇒ x = 20*t <em>(i)</em>
Carro B
x = x₀+v*t
⇒ x = 500 + 18*t <em>(ii)</em>
Se as equações são as mesmas, verifica-se <em>(i) = (ii)</em>
20*t = 500 + 18*t
⇒ 20*t - 18*t = 500
⇒ 2*t = 500
⇒ t = 250 s = 4.167 s
Answer:
a) 0.018 kg
b) 262 kPa
Explanation:
The volume of the concentric cylinders would be:
V = π/4 * h * (D^2 - d^2)
V = π/4 * 13 * (52^2 - 33^2) = 16500 cm^3 = 0.0165 m^3
The state equation of gases:
p * V = m * R * T
Rearranging:
m = (p * V) / (R * T)
R is 287 J/(kg * K) for air
25 C = 298 K
m0 = 202000 * 0.0165 / (287 * 298) = 0.039 kg
After pumping more air the volume remains about the same, but temperature and pressure change.
30 C = 303 K
m1 = 303000 * 0.0165 / (287 * 303) = 0.057 kg
The mass that was added is
m1 - m0 = 0.057 - 0.039 = 0.018 kg
If that air is cooled to 0 C
0 C is 273 K
p = m * R * T / V
p = 0.057 * 278 * 273 / 0.0165 = 262000 Pa = 262 kPa
