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.

Answer:
a) force = mass * acceleration
so,
F=87*9.8
=852.6 N (newtons)
b) in the real world, the force affecting the rste of fall is most likely Air Resistance!
Answer:
Gravity.” or “Gravity causes the moon to orbit the earth.” “Acceleration due to gravity” is much more precise. It is the acceleration that an object experiences when it is dropped with no other external forces on it. ... Near the surface of the earth the acceleration due to gravity is about 9.8
