The biggest one is when we breathe from our nose and mouth
Answer:
Answer:
Without it information flow is impossible
Explanation:
The word 'pivotal' also means crucial or vital, and so we need to consider what an operating system actually does. Remember, merely having all the hardware of a computer would not allow you to run (install and use) programs. It is by means of an operating system that teaching programs can be installed, and it is also by means of an operating system learning can take place. For example, a student can decode (learn) instructions / lessons from his teacher via a software program; and the software program needs an operating system to open (run) the program.
Answer:
It's most likely CAH102, if not i'm sorry
Explanation:
Answer:
5.76 cm³
Explanation:
Using the equation for volume expansivity,
V = V₀ + V₀γΔθ) where V₀ = volume of cube = volume of mercury = 400 cm³, γ = cubic expansivity of mercury = 18 × 10⁻⁵ /K and Δθ temperature change = θ₂ - θ₁ where θ₁ = 0 °C and θ₂ = 80°C. So, Δθ = 80°C - 0°C = 80°C = 80 K
Now, the volume change, ΔV = V - V₀ = V₀γΔθ.
So, substituting the values of the variables into the equation, we have
ΔV = V₀γΔθ
= 400 cm³ × 18 × 10⁻⁵ /K × 80 K
= 5.76 cm³
So the mercury will overflow by 5.76 cm³.
