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
do you have a formulai can do this problem
Answer:
Question 1: the plates are moving toward one another.
Question 2: The Himalayan Mountains in India
Question 3: Because mountains are formed instead.
Explanation:
The paragraph explains that the plates continue to move closer to one another while forming multiple mountains.
The paragraph explains, " a well-known example of this is the formation of the Himalayan Mountains in India,"
The area of the Himalayan Mountains are better suited for the formation of mountains rather than volcanoes.
Have a nice day!! Good Luck!! Brainliest would be appreciated!!!
Answer:
The induced current is 26.7 mA
Explanation:
Given;
area of the loop, A = 0.078 m²
initial magnetic field, B₁ = 3.8 T
change in the magnetic field strength, dB/dt = 0.24 T/s
The induced emf is calculated as;

The resistance of the loop = 0.7 Ω
The induced current is calculated as;
