Density is mass divided by volume. rho=m/v. So, v=m/rho. In frank's case this is 80/8 = 10 cm^3.
        
             
        
        
        
Answer:
people separate mixtures in order to ger a specific substance that they need. 2. the other thing people separate mixtures to remove the unrequired components. 3.To get a pure substance

If the box is a distance 1.81 m from the rear of the truck when the truck starts,<span> ... Force of Friction = mu_s * Normal Force( </span>M<span> * G) ... The </span>box starts<span> moving! ... Now that the </span>box<span> is moving, the bed of the </span>truck<span> pulls at it with 17.4 ... out how </span>long<span> it will take the </span>box<span> to reach the back of the </span>truck<span>. ...

Answer:
For the car to move with constant velocity the additional force required is  
Explanation:
From the question we are told that 
   The net force of the car is  
Generally the total  force acting on the  car is the net force plus the force due to gravity acting in direction of the car (Let denote it as  )
) 
So the total force acting on the car is mathematically represented as 
         
Here this F representing the total force can be mathematically represented as 
       
Now for constant velocity to be attained, the acceleration of the car will be zero  
So  at constant velocity 
        
=>    
So  
      
=>   
=>
