The phone gives off sound waves, and the sound waves go into your ear to be interpreted by ur brain

Personally, I call it the wave's "amplitude".

What do YOU call it ?

Ondrea could drive a Jetson's flying car at a constant speed of 540.0 km/hr across oceans and space, approximately how long woul

Tcecarenko [31]

Answer:

The time taken in years is $x = 125 \ years$

Explanation:

From the question we are told that

The speed is $v = 540.00 \ km /hr = \frac{540 *1000}{3600} = 150\ m/s$

The distance from the sun to Pluto is $d = 5.9*10^{9} \ k m = 5.9*10^9 * 1000 = 5.9*10^{12} \ m$

Generally the time taken is mathematically represented as

$t = \frac{d}{v}$

=> $t = \frac{5.9*10^{11}}{150}$

=> $t = 3.933*10^{9}$

Converting to years

$1 year \to 3.154*10^7 \ s$

$x \ years \to 3.933*10^{9}$

=> $x = \frac{ 3.933*10^{9} * 1 }{ 3.154 *10^7}$

=> $x = 125 \ years$

Three equal point charges, each with charge 1.15 μCμC , are placed at the vertices of an equilateral triangle whose sides are of

julsineya [31]

Answer:

$U=50.96J$

Explanation:

The electrostatic potential energy for pair of charge is given by

U=1/4π∈₀×(q₁q₂/r)

Hence for a system of three charges the electrostatic potential energy can be found by adding up the potential energy for all possible pairs or charges.For three equal charges on the corners of an equilateral triangle,the electrostatic potential energy is given by:

U=1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)+1/4π∈₀×(q²/r)

U=3×1/4π∈₀×(q²/r)

Substitute given values

$U=3\frac{1}{4\pi E_{o} }\frac{q^{2} }{r}\\ U=3\frac{1}{4\pi8.85*10^{-12} }\frac{(1.15*10^{-6}C )^{2} }{0.0007m}\\ U=50.96J$
