Auniform electric field exists everywere in the x, y plane. this electric field has a magnitude of 4500 n/c and is directed in the positive x direction. a point charge -8.0 x 10^-9c is placed at the origin. determine the magnitude of the net electric field at (a.) x= -0.15 m, (b.) x= +0.15 m, and (c.) y= +0.15 m.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
