Answer:
0.67m/s²
Explanation:
Given parameters: 
Mass of toy  = 1.2kg 
Force applied = 0.8N 
Unknown: 
Acceleration   = ? 
Solution: 
According to newton's second law of motion;
       Force  = mass x acceleration
Now, 
       Acceleration =  
 
      Acceleration  =  = 0.67m/s²
   = 0.67m/s²
 
        
                    
             
        
        
        
Answer:

Explanation:
The work done on a particle by external forces is defined as:

According to Newton's second law  . Thus:
. Thus:

Acceleration is defined as the derivative of the speed with respect to time:

Speed is defined as the derivative of the position with respect to time:

Kinetic energy is defined as  :
:

 
        
             
        
        
        
Answer
aim directly at the image
Explanation 
the light from the laser beam will also bend when it hits the air water interface , so aim directly at the fish
 
        
             
        
        
        
It is most likely true that there was a lower concentration of salt in the water than in the cells because when blood cells are put in a hypotonic solution such as pure water, the little to no salt concentration in the water causes the cells to swell and burst. This would occur because the water would try to dilute the solution inside of the blood cell and which would, therefore, cause it to burst. Hope this helps!
