To receive AM radio, you want an RLC circuit that can be made to resonate at any frequency between 500 and 1650 kHz. This is acc
levacccp [35]

The formula for resonant frequency is:

f_0=\frac{1}{2\pi\sqrt{LC} }

Given information:

f_{0\text{,small}}=500 \text{ kHz}\\f_{0\text{,large}}=1650 \text{ kHz}\\L=3.83\text{ } \mu \text{H}

Plug in the given values to find one value of capacitance:

500 \text{ kHz}=\frac{1}{2\pi\sqrt{C(3.83\text{ } \mu \text{H})} }\\C=2.645*10^{-8} \text{ F}=26.45 \text{ nF}

Plug in the given values to find the other value of capacitance:

1650 \text{ kHz}=\frac{1}{2\pi\sqrt{C(3.83\text{ } \mu \text{H})} }\\C=2.429*10^{-8} \text{ F}=2.429 \text{ nF}

This gives a range of 2.429 nF to 26.45 nF.

With significant figures taken into account, the range of capacitance is 2.43 nF to 30 nF.

Two frisky otters slide down frictionless hillsides of the same height but different slopes. The slope of the hill of otter 1 is
alexdok [17]

Answer:

The  frisky otters will be moving at the same speed  at the bottom of the hill because the hillsides are of the same height

Explanation:

From the question we are told that

   The slope of the hill of otter one is \theta_1 =  30^o

   The slope of the hill of otter two  is  \theta _2 =  60^o

Generally the from the law of energy conservation

     PE_{top} =  KE_{bottom}

Here  PE_{top} =  mgh

and  KE_{bottom} =  \frac{1}{2} mv^2

So

       mgh  = \frac{1}{2} m v^2

=>   v = \sqrt{2gh}

From this equation for v we see that velocity is only dependent on the height and is not affected by the slope

Hence both frisky otters will travel at same speed because the hillsides are of the same height
