Answer:
A) Although the speed is the same, the direction has changed. Therefore, the velocity has changed.

The energy in ordinary light is greater than the energy in ordinary sound
Energy is the ability to perform work in physics. It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc. Additionally, there is heat and work, which is energy being transferred from one body to another.
Energy is a physical system's ability to perform labor. The capital letter E is a typical sign for energy. The joule, denoted by the letter J, is the common unit. The energy produced by one newton's (1 N) worth of force acting over one meter's (1 m) worth of displacement is measured in joules (1 J). Because it is a fundamental human requirement, energy plays a significant role in our daily lives.

Answer:
 α = 13.7 rad / s²
Explanation:
Let's use Newton's second law for rotational motion
          ∑ τ = I α
          
we will assume that the counterclockwise turns are positive
          F₁  0 + F₂ R₂ - F₃ R₃ = I α
give us the cylinder moment of inertia
         I = ½ M R₂²
          
         α = (F₂ R₂ - F₃ R₃)  
let's calculate
         α = (24  0.22 - 13  0.10)  2/12 0.22²
2/12 0.22²
         α = 13.7 rad / s²
 
        
             
        
        
        
Answer:
 Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.
