Answer:
The pressure difference is <em>.</em>
Explanation:
To calculate the pressure difference, we use the fluid-kinetic equation:
<em>Δp = (8μLQ)/(πR⁴)</em>
Step 1: Convert the units of the given terms to SI units:
Diameter = 0.56 cm X ( =
∴ Radius, R =
Length, L = 22 cm X ( = 0.22 m
Volumetric flow rate, Q = ÷ 2.0 minutes =
X X =
Step 2: Input the terms into the fluid-kinetic equation:
<em>Δp = (8 X 0.60 X 0.22 X 3.67) / (3.142 X ()</em>
<em>Δp = 20067.43 Pa = .</em>
N.B: The pressure difference is lower than the atmospheric pressure (101300 Pa), which means you can drink the milkshake through the straw.
The net force acting on the center O is 4.495 X 10⁹ N
<u>Explanation:</u>
Given:
Charge-
q₁ = 4C
q₂ = 3C
q₃ = -5C
q₄ = 2C
q₅ = 1C
Side of the square = 4cm
Net force acting on the center, F = ?
Length of the side of the square is 4cm
The length of the diagonal will be 4√2
The length of half diagonal = 4√2 / 2 = 2√2
Force acting on the center of the square is:
Here, k is coulomb's constant and the value is
k = 8.99 x 10⁹ N m2 / C2
On substituting the value, we get:
Therefore, the net force acting on the center O is 4.495 X 10⁹ N
