Answer:
<h2>90 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 30 × 3
We have the final answer as
<h3>90 J</h3>

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.
