The "it must be five times larger" current change if the energy stored in the inductor is to remain the same.
<u>Explanation:</u>
A current produced by a modifying magnetic field in a conductor is proportional to the magnetic field change rate named INDUCTANCE (L). The expression for the Energy Stored, that equation is given by:
Here L is the inductance and I is the current.
Here, energy stored (U) is proportional to the number of turns (N) and the current (I).
mu not - permeability of core material
A -area of cross section
l - length
N - no. of turns in solenoid inductor
Now,given that the proportion always remains same:
In this way the expression
Thus, it suggest that "it must be five times larger" current change if the energy stored in the inductor is to remain the same.
Answer:
Explanation:
Thinking process:
Let the radius = 6 m
The rate of removal of the beer = 15 m³/hr
This can be written as:
the rate or change
this changes to
Answer:
0.25p.a
Explanation:
force=15N area=60m²
so pressure =force/area =15N/60m²=0.25p.a
Answer: 1600 km from the surface
Explanation:
Therefore, 8000 km - 6400 km = 1600 km from the surface
Answer is: <span>canoe's kinetic energy is 136 J.
</span>m(canoe) = 17 kg.
v (speedcanoe) = 4 m/s.
E(canoe's kinetic energy) = ?
E = 1/2 · m(canoe) · v²(canoe).
E = 0,5 · 17 kg · 16 m²/s².
E = 136 J.
<span>The kinetic energy of a non rotating object of </span>mass m<span> traveling at a </span>speed v. <span>The standard unit of kinetic energy is the </span>joule.
