Answer:
Work done, W = -318.19 Joules
Explanation:
It is given that,
Force acting on the object, F = 50 N
Distance covered by the force, d = 9 m
Angle between the force and the distance traveled, 
The work done by an object is equal to the product of force and distance traveled. It is equal to the dot product of force and the distance. Mathematically, it is given by :


W = -318.19 Joules
So, the work done by the force is 318.19 Joules. The work is done in opposite to the direction of motion. Hence, this is the required solution.
 
        
             
        
        
        
Answer:
   I = 12 A
Explanation:
For this exercise we use the relationship that voltage is proportional to the product of current and resistance
            V = I R
             I = V / R
              
let's calculate
             I = 120/10
             I = 12 A
 
        
             
        
        
        
Answer:
they are the source of energy for primary consumers... they also produce oxygen and sugar
 
        
                    
             
        
        
        
Turning on a flashlight uses a battery, right? Chemical energy is stored in that battery. If you use the battery, you're converting that chemical energy to an electrical energy.
In a flashlight then, the electrical energy becomes light energy and thermal energy in the bulb. Why light and thermal? The flashlight gives us light and then, gives out heat. This is why when we touch light bulbs, it feels hot.
