The electric potential in a particular region of space varies only as a function of y-position and is given by the function V(y)

nikdorinn [45]

Answer:

$E = 55.9583\ Volts/meter$

Explanation:

First let's find the electric potential using y = 22.5:

$V(y) = 1.69y^2 +15.6y+52.5$

$V(22.5) = 1.69(22.5)^2 + 15.6*22.5 + 52.5$

$V(22.5) = 1259.0625\ Volts$

Then, to find the magnitude of the electric field, we just need to divide the electric potential by the distance y:

$E = V/d$

$E = 1259.0625/22.5$

$E = 55.9583\ Volts/meter$

QveST [7]

Answer:

Use the formula

g = GM/R^2

where

g = acceleration of gravity on moon

G = universal gravitational constant

= 6.67 x 10^-11 m^3/kg-s^2

M = mass of the moon

R = radius of the moon

solving for R, we get

R = 1.74 x 10^6 kg
