<span>We calculate the electric field as follows:
r = </span>√<span>(3)/6 x 19 cm = .05484 m
The angle for the triangle would be 30 on each side.
tan(30) = r/(L/2)
E' = kQ/{r*sqrt[(L/2)^2 + r^2]} = (8.99e9 x 15e-9) / {.05484 * sqrt[(.19/2)^2 + .003]}
</span>E' <span>= 22413 N/C
The value above is the electric field strength for a single rod at the center.
|E'| = 22413 N/C
E = 2|E'|sin(30) + |E'| = 49000 N/C</span>
The correct answer is 0.67 h
The coil's induced emf is specified as e=0. 50 v.
i i = 0.55 A is the initial value of the current flow.
I f = 0.95 A is the total amount of current flowing.
The shift in current occurs in a period of time when dt = 0.40 s.
The self-inductance is determined as follows:
The current change rate is represented here by dI/dt.
Step 2 After entering the values,
As a result, the self-inductance is 0.67 H.
The definition of self inductance is the induction of a voltage in a wire that carries current when the current in the wire is changing. When there is self-inductance, a circuit's own changing current creates a magnetic field that causes a voltage to be induced.

Answer:
2.75 m/s^2
Explanation:
The airplane's acceleration on the runway was 2.75 m/s^2
We can find the acceleration by using the equation: a = (v-u)/t
where a is acceleration, v is final velocity, u is initial velocity, and t is time.
In this case, v is 71 m/s, u is 0 m/s, and t is 26.1 s Therefore: a = (71-0)/26.1
a = 2.75 m/s^2
I’m unsure of the answer, but it is not b.
The potential energy that the ball has at the top of the tower is its kinetic energy when it hits the ground. The second ball has more potential energy at the top, because you did more work on it to carry it up there. So it has more KE at the bottom. (A)
