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>

An electron starts from rest in a vacuum, in a region of strong electric field. The electron moves through a potential differenc
Semenov [28]

Answer:

The kinetic energy is  KE  = 5.67*10^{-18} \ J

Explanation:

From the question we are told that

    The potential difference is  \Delta V  =  36 \ volts

       

The potential energy of the end  is mathematically represented as

        PEs  =  - q *  \Delta V

q  is the charge on an electron with a constant value of q =  1.60 *10^{-19} \  C

       substituting values

      PE  =  - 1.60*10^{-19} *  36

      PE  =  -  5.67*10^{- 18} \ J

Now from the law of energy conservation

     The PE_e    =  KEe

Where  KE _e is the potential  energy at the end

 So  

        KE  = 5.67*10^{-18} \ J

The  negative sign is not includes because kinetic energy can not be negative

A car travels 36 km in 30 minutes. The speed of the car is
iogann1982 [59]

Answer:

72km/hr

Explanation:

Speed in Km is usually represented in hours. so if the car is in constant velocity, and if the car travels 36km in 30 min then it travels 72km in 1 hour.

so the speed of the car is 72km/hr
