As charges move in a closed loop, they gain as much energy as they lose.
<h3>What is principle of 
conservation of energy?</h3>
- According to the principle of conservation of energy, in a closed or isolated system, the total energy of the system is always conserved. 
- The energy gained by the particles or charges in a closed system is equal to the energy lost  by the charges.
Thus, we can conclude the following based on principles of conservation of energy;
- As charges move in a closed loop, they gain as much energy as they lose.

Answer: length of B =4.00
Explanation:
for  the vectors A and B and the angle between them as  x.
Magnitude of the sum of A and B is  given as = √(A²+B²+2ABcosx
 where 
Magnitude of A  = 3.00 
Magnitude of the sum of A and B is  5.00
5.00=√(A²+B²+2ABcos90°
5.00= √3² +b² +0
5²= 3² +b² 
25=9+b²
b²= 25-9
b² = 16
b=  √16
b= 4
 
        
             
        
        
        
Answer:
(A) Impulse = 9Ns
(B) F = 1286N 
Explanation:
Impulse = change in momentum = m(v-u)
v = 0 (the hand comes to a stop)
u = -10m/s 
Mass = 0.9kg
 Impulse = 0.9 ×(0- (-10))
 = 9Ns
(B) F×t = Impulse
F = Impulse/ t 
t = 7ms = 7×10-³
F = 9/ (7×10-³)
F = 1286N.
