Answer:
induced EMF = 240 V
and by the lenz's law  direction of induced EMF is opposite to the applied EMF
Explanation:
given data 
inductance = 8 mH 
resistance = 5 Ω
current = 4.0 A
time t = 0
current grow = 4.0 A to 10.0 A 
to find out 
value and the direction of the induced EMF
solution
we get here induced EMF of induction is express as 
E = - L  ...................1
    ...................1
so E = - L 
put here value we get 
E = - 8 ×  
 
E = -40 ×  6 
E = -240 
take magnitude 
induced EMF = 240 V
and by the lenz's law we get direction of induced EMF is opposite to the applied EMF

The antacid is basic so it neutralizes acidity or lowers it. Then if it goes into the esophagus, it's not as strong and it doesn't hurt, and it also calms your stomach because the acidity in your stomach is also lower. Antacids are therefore taken by many people, especially as they grow older and things like heartburn become more common.
