To find the net charge you take the number of protons and subtract the number of electrons, and the answer will be your charge.
This atom has 11 electrons AND 11 protons
11 - 11 = 0 net charge
Ok yeah yeah yeah yeah yeah
Answer:
La ciencia y la tecnología se complementan porque la tecnología necesita que la ciencia sea una cosa y la ciencia se usa en tecnología
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.
Answer:
ML2T-2
Explanation:
Work= Force × displacement
=>
work= [MLT^-2] [L]
W= [ML2T-2]
