Answer:
The angular displacement would be 6 Pi radians or 1080 degrees.
Explanation:
Every individual rotation is 2 Pi (this applies to anything regardless of radius).
Since there are three rotations you are going to multiply 2 Pi by 3.
This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).
Answer:
The linear mass density of rope is 0.16 kg/m.
Explanation:
mass, m = 0.52 kg
force, F = 47 N
length, L = 3.3 m
(a) The linear mass density of the rope is defined as the mass of the rope per unit length.
Linear mass density = m/L = 0.52/3.3 = 0.16 kg/m
The correct answer is 9.45 kg.
The formula for calculating the density of an object is expressed as:
Density = mass / volume
Given :
Density = 150kg/m³
Volume of the sphere = negligible
r is the radius = 50/2 = 25cm = 0.25m
We can find the volume of the Styrofoam sphere by
=(4/3)πr³
Volume (V) = (4/3)*π*(0.25)³
Volume = 0.063 cm³
Now let us find the required mass:
Mass = density * volume
Mass = 150 * 0.063
Mass = 9.45 kg
Therefore, the maximum mass that can hang without sinking from a 50.0 cm -diameter Styrofoam sphere in water is 9.45 kg.

Answer:
You can compare and contrast the scientific method to the engineering design process
Explanation:
Final velocity=2m/s
kinetic energy lost = 96J
Explanation:
This question is an example for total inelastic collision.
For this type of collision, the equation is,
Step1: Finding the velocity
m1v1+m2v2 =(m1+m2) vf
4*8+12*0 = (4+12)v
32 = 16v
= 2m/s
Step 2:Finding the kinetic energy
Kinetic Energy before collision=
Kinetic Energy before collision= 128J
Kinetic Energy after collison= 32J
Step 3: Finding the kinetic energy lost
Kinetic Energy lost = Kinetic Energy after collision – Kinetic Energy before collision
Kinetic energy lost=128 -32
Kinetic energy lost=96J
