Answer:
The mercury in the barometer rises by a height of 0.0764 m = 76.4 cm = 764 mm
Explanation:
The change in pressure is related to the density of fluid and height risen by the fluid through the relation
ΔP = ρgh
ΔP = change in pressure = P₂ - P₁ = 1.1 - 1.0 = 0.1 atm = 0.1 × 101325 Pa = 10132.5 Pa
ρ = density of the fluid = 13,534 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = height through which the mercury in barometer rises = ?
10132.5 = 13534 × 9.8 × h
h = (10132.5) ÷ (13534 × 9.8)
h = 0.0763948996 = 0.0764 m = 76.4 cm = 764 mm
Hope this Helps!!!
Answer:
Explanation:
In order to find the force between the two electrons, we need to use Coulomb's law. In its scalar form, the law is given by:
Where:
The electric charge of an electron is a known constant given by:
So:
Therefore, replacing the data provided in the Coulomb's law equation:
Answer:
The answer is A.
Explanation:
They both work together to circulate oxygen and blood throughout the body.
Answer: <em>One main reason, all three experts agree, is the phenomenon known as “windthrow” which uproots a tree. “The tree trunk acts as a lever and so the force applied to the roots and trunk increases with height,” says Foster. “Taller trees are more susceptible to windthrow.”</em>
