Answer:

They come in different kinds, called elements, but each atom shares certain characteristics in common. All atoms have a dense central core called the atomic nucleus. ... All atoms have at least one proton in their core, and the number of protons determines which kind of element an atom is.

s A horizontal insulating rod of length 11.0-cm and charge 19 nC is in a plane with a long straight vertical uniform line charge

guajiro [1.7K]

Answer:

F = 2.26 × 10⁻³ N

Explanation:

given,

length of rod = 11 cm

charge = 19 nC

linear charge density = 3.9 x 10⁻⁷ C/m

electric force at 2 cm away.

$E(r) = \dfrac{2K\lambda}{r}$

F = E q

$F= \dfrac{2K\lambda\ q}{L}\int \dfrac{dr}{r}$

integrating from 0.02 to 0.02 + L

$F= \dfrac{2K\lambda\ q}{L}[ln(0.02+L)-ln(0.002)]$

$F= \dfrac{2\times 9 \times 10^9\times 3.9\times 10^{-7}\times 19 \times 10^{-9}}{0.11}[ln(0.02+0.11)-ln(0.002)]$

F = 2.26 × 10⁻³ N

How much force (in Newtons) acts on a 1700 kg car going around a

Daniel [21]

Answer:

b) 4781 N

Explanation:

Because there is a redius do this question is talking about the acceleration force which= mv^2/r

so a=15^2/80=2.8125 m^2/s

so the force will be = m.a

F =1700×2.8125=4781.25 N
