An emf of 0.50 v is induced across a coil when the current through it changes uniformly from 0.55 to 0.95 a in 0.40 s. what is t

love history [14]

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.

A forward horizontal force of 12n is used to pull a crate across a horizontal floor at a constant velocity. If the crate weighs

kow [346]

Explanation:

μ = coefficient of friction.

F = Frictional force = 12N

R = Normal reaction = mg = Weight = 240N

m = mass

g = acceleration due to gravity ≈ 9.8ms—²

μ = F/R

μ = 12/240

μ = ¹/20

μ = 0.05

Vladimir [108]

Answer:

v=4m/s

Explanation:

The formulas for accelerated motion are:

$v=v_0+at\\x=x_0+v_0t+\frac{at^2}{2}$

We can derive the formula $v^2=v_0^2+2ad$ from them.

We have:

$v-v_0=at\\t=\frac{v-v_0}{a}$

And substitute:

$x=x_0+v_0(\frac{v-v_0}{a})+\frac{a}{2}(\frac{v-v_0}{a})^2\\x-x_0=\frac{v_0(v-v_0)}{a}+\frac{(v-v_0)^2}{2a}\\2a(x-x_0)=2v_0(v-v_0)+(v-v_0)^2=2v_0v-2v_0^2+v^2+v_0^2-2vv_0=v^2-v_0^2$

Where in the first step of the last row we just multiplied everything by 2a. Since $x-x_0$ is the displacement d, we have proved that $v^2=v_0^2+2ad$

We use then our values to calculate the final velocity when starting from rest, traveling a distance 0.002m with acceleration $4000 m/s^2$ :

$v=\sqrt{v_0^2+2ad}=\sqrt{2(4000m/s^2)(0.002m)}=4m/s$
