Answer:
Explanation:
Given that
Constant current I=15A
Inductance L=2.8H
a. Current changes from 15A to 0A.
∆I=0-15=-15
For a time of t=75ms=0.075s
EMF=?
EMF is given at
EMF=-L(∆I/t)
EMF=-2.8×-15/0.075
EMF=3.15V
b. Energy stored?
Energy stored is given as
E=½LI²
E=½×2.8×15²
E=315 J
c. Rate of energy? Which is power and the rate of energy is given as
Power=Energy/timetaken
Power=315/0.075
Power=4200W
P=4.2KW
Answer:
Explanation:
Given that,
The density of iron is 7.97 g/cm³.
We need to find the density in SI unit. The SI unit of density is kg/m³.
We know that,
1 kg = 1000 g
1 m = 100 cm
So,
So, the density of the iron is .
Answer:
The first one is seafloor spreading and the second is subduction
