The answer would be B.
(V=IR, 12-10i, 12/10=1.2)
        
             
        
        
        
Answer:
 The speed does it head toward the goal = 41.87 
Explanation:
Mass = 0.107 kg 
Initial velocity ( u ) = 0
Force (F) = 28 N
Time = 0.16 sec
From newton's second law,  Force  = mass × acceleration 
⇒  F = m × a 
⇒  28 = 0.107 × a 
⇒  a = 261.7  --------- (1)
 --------- (1)
This is the value of acceleration. 
Final speed of the mass is calculated by the equation V = U + at
⇒ U = 0 because mass in in rest position at start. 
⇒ V = a t
Put the values of acceleration and time in above formula we get 
⇒ V = 261.7 × 0.16 
⇒ V = 41.87 
Therefore the speed does it head toward the goal = 41.87 
 
        
             
        
        
        
Answer:
21s
Explanation:
Given parameters;
Radius  = 10m 
Speed or velocity  = 3m/s 
Unknown: 
Period  = ? 
Solution: 
 To solve this problem, use the expression: 
       v  =  
  
r is the radius 
T is the unknown
            Input the parameters and solve for T; 
     3  =  
  
     62.84 = 3T 
          T  = 21s
 
        
             
        
        
        
Answer:
C) Unscrew one light. If the other lights turn off, it's a series circuit.
Explanation:
THIS IS THE COMPLETE QUESTION BELOW;
A strand of 10 lights is plugged into an outlet. How can you determine if the lights are connected in series or parallel? A) Unscrew one light. If the other lights stay on, it's a series circuit. B) Unplug the strand. If the first light stays on, it's a series circuit. C) Unscrew one light. If the other lights turn off, it's a series circuit. D) Cut the strand in half. If the plugged in half stays on, it's a series circuit.
SERIES CIRCUIT
In this circuit, the components there are in the same path, the entire circuit has the same current, each of the components posses different voltage drop. Hence, failure of one components to work, there will be break in entire circuit then other components cease to work.
PARALLEL CIRCUIT
This circuit has equal voltage drop across all the components, any problem in a component will not has effect on other components.
 Therefore, if one want to determine if a light connection is in series or in parallel, one of the light can be unplugged if others stop working it means it's series, if other works it's parallel.
 
        
             
        
        
        
Answer:
   an object sliding down hill 
Explanation:
On a slope, the force applied is due to gravity. Its direction is straight down. If the object is sliding down the hill, its displacement is at an angle to the applied force. The angle of displacement will depend on the steepness of the hill.
