Answer:
ΔV=V1-V2 = 27692307.69volts
Explanation:
Hello! Let's solve this!
The formula to calculate the power difference is
ΔV=V1-V2
V = k * (q / r)
k is a constant that equals
The data we have are:
r = 0.0013m
From the following formula we can calculate how much q2 is
F = k * (q1 * q2 / r2)
q2 = (F * r2) / (k * q1)
q2 = (15*10^{-6} N[/tex] * 0.00132) / (9*10^{9}N*m^{2}/C^{2}[/tex] *40*10^{-6}C\)
Now we calculate with q1 and q2, V1 and V2 respectively.
V1 = (9*10^{9}N*m^{2}/C^{2}[/tex] * 40*10^{-6}C\) /0.0013m
V1 = 27692307.69 volts
V2 = (9*10^{9}N*m^{2}/C^{2}[/tex] * 7.0417x^{-17}C[/tex]) /0.0013m
Then we solve the potential difference:
V1-V2 = 27692307.69 volts-4.875*10^{-4}volts[/tex]
ΔV=V1-V2 = 27692307.69volts
If air were a good conductor of heat" then soup will not stay hot for longer because this time convection+conduction will both help to transfer heat away from soup. Because conduction is the transfer of heat through a substances as a result of neighbouring vibrating particles, The particles in air are far apart.
The correct answer is C. She did no work because she did not move the scales or sword while she posed.
Explanation:
In physics, the term "work" is used to refer to the energy or force related to the displacement of an object. Indeed, this variable is calculated through the formula W (work) = F (force) x d (displacement). This implies, there is only work if there is displacement. According to this, Brandi did no work while posing because even if she used her force to hold the scales and sword she did not move and displacement is essential for work to exist. Thus, the correct option is C.
