Answer:
k = 1,250 N/m
Explanation:
Use the formula F=kx, with F=5N and x=0.04m
Then the spring constant (k) is 5/0.04

Explanation: I got it right on edge2021 :)
The choice of path should make no difference. The work should depend only on the end points and not on the route between them. But just to make sure, could we please have a look at the accompanying figure ?
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:
Frictional force is produced when two bodies are rubbed against each other. It is the force that oppose the motion and therefore it stops or slow down a moving body.It depends upon the roughness or smoothness of the surface of the body in contact.Rough surface have more friction that the smooth surface. Similarly, the heavier body produces more friction than a lighter body. Frictional force acts in the opposite direction of the motion of the body.
