Answer:
Joule 
Explanation:
energy, work, quantity of heat 
 
m2·kg·s-2
 
        
             
        
        
        
Kinetic energy is movement, thus movement would be a characteristic that allows an object to have kinetic energy
        
             
        
        
        
Answer:
The electric flux is 
Explanation:
Given:
- Radius of the disc R=0.50 m
- Angle made by disk with the horizontal  
- Magnitude of the electric Field  
The flux of the Electric Field E due to the are dA in space can be found out by using Gauss Law which is as follows

where
 is the total Electric Flux is the total Electric Flux
- E is the Electric Field
- dA is the Area through which the electric flux is to be calculated.
Now according to question we have

Hence the electric flux is calculated.
 
        
             
        
        
        
Answer:
 
 
Max speed = 
Max acceleration = 
Explanation:
Given the description of period and amplitude, the SHM could be described by:

and its angular velocity can be calculated doing the derivative:

And therefore, the tangential velocity is calculated by multiplying this expression times the radius of the movement (3 m):
 and is given in m/s.
  and is given in m/s.
Then the maximum speed is obtained when the cosine function becomes "1", and that gives:
Max speed = 
The acceleration is found from the derivative of the velocity expression, and therefore given by:

and the maximum of the function will be obtained when the sine expression becomes "-1", which will render:
Max acceleration = 
 
        
             
        
        
        
“a point at which rays of light, heat, or other radiation meet after being refracted or reflected.” Meaning multiple light rays or heat (and other forms of radiation) are all being refracted or reflecting to a certain point
