Phantasy [73]3 years ago

Current requires only an EMF source ... like a battery, or a current already flowing ... and a conducting path ... like wire, ionized air, or something dissolved in water. A switch isn't needed unless you want a quick, easy way to STOP the current. A resistor isn't needed unless you want to be able to dissipate some energy from the current, or limit its magnitude.

7 the density of the american white oak tree is 752 kilograms per cubic meter. if the trunk of an american white oak tree has a
alexdok [17]

First, we determine the volume of the trunk by finding first the radius from the circumference through the equation,

<span>                                                            C = 2πr</span>

<span>                                                            r = C/2π</span>

Substituting the known values,

<span>                                                            r = 4.5/2π = 0.716 m</span>

Then, we calculate for the volume through the equation,

<span>                                                            V = πr2h</span>

<span>                                                V = π(0.716 m)2(8m) = 12.9 m3</span>

Multiplying the calculated value to the density will give the mass as,

<span>                                                Mass = (12.9 m3)(752 kg/m3) = <span>9699.36 kg</span></span>
