An inductor is connected to the terminals of a battery that has an emf of 16.0 V and negligible internal resistance. The current

balu736 [363]

Answer:

(a) The resistance R of the inductor is 2480.62 Ω

(b) The inductance L of the inductor is 1.67 H

Explanation:

Given;

emf of the battery, V = 16.0 V

current at 0.940 ms = 4.86 mA

after a long time, the current becomes 6.45 mA = maximum current

Part (a) The resistance R of the inductor

$R = \frac{V}{I_{max}} = \frac{16}{6.45*10^{-3}} = 2480.62 \ ohms$

Part (b) the inductance L of the inductor

$\frac{Rt}{L} = -ln(1-\frac{I}I_{max}})\\\\L = \frac{Rt}{-ln(1-\frac{I}I_{max})}}$

where;

L is the inductance

R is the resistance of the inductor

t is time

$L = \frac{Rt}{-ln(1-\frac{I}I_{max})}} = \frac{2480.62*0.94*10^{-3}}{-ln(1-\frac{4.86}{6.45})} \\\\L =\frac{2.3318}{1.4004} = 1.67 \ H$

Therefore, the inductance is 1.67 H

A particle moves so that its position as a function of time in SI units is r = i + (3.0) t2 j + t k. Write expressions for its v

maksim [4K]

Answer:

i - component of V is zero for any value of t i-e no motion in this direction

Explanation:

Since

r= i+3 $t^{2}$ j+t k

==> V = $\frac{d r}{dt}$ = $\frac{d(i+3t^{2}j+kt) }{dt}$

= $6tj+k$

and acceleration is given by taking derivative of velocity w.r.t t

==> a= $\frac{dV}{dt}$ = $\frac{d(6tj+k)}{dt}$ = $6j$

so, V=0i+6tj+k

and

a = 0i+6j+k

i - component of V is zero for any value of t i-e no motion in this direction

A scientist performs an experiment on an unknown element. She finds that the element forms an ionic bond with beryllium (Be) but

Bumek [7]

To fill up all of the valence electrons we must have 8 electrons total to have an ionic bond. In this case Lithium is in group 1 and so only has 1 valence electron and so it can bond with elements from group 17, since 7 + 1 = 8. However, this unknown element did bond with beryllium, and beryllium is in group 2 so it must bond with an atom that has 6 valence electrons. The elements that have 6 valence electrons are in group 16 not group 2. So the result does not support her conclusion.
