Three equal point charges, each with charge 2.00 μC , are placed at the vertices of an equilateral triangle whose sides are of l
oksano4ka [1.4K]

Answer:

Explanation:

Energy of system of charges

= k q₁q₂ / r₁₂ + k q₁q₃ / r₁₃ + k q₃q₂ / r₃₂

q₁ , q₂ and q₃ are charges and  r₁₂ , r₁₃ , r₃₂ are densities between them

9 x 10⁹ ( 2x2 x10⁻¹²/ .25 + 2x2 x10⁻¹²/ .25 + 2x2 x10⁻¹²/ .25 )

= 9 x 10⁹  x 3 x 16 x 10⁻¹²

= 432 x 10⁻³

= .432 J .

2. Categorize each statement as true or false. A cylindrical capacitor is essentially a parallel-plate capacitor rolled into a t
Kruka [31]

Answer:

Explanation:

False --> A cylindrical capacitor is essentially a parallel plate capacitor rolled into a tube. This is because a cylindrical capacitor comprises two cylinders.

False --> The dielectric constant indicates the distance by which the two plates of a capacitor are separated.

True --> The charge on a capacitor increases quickly at first, then much more slowly as the capacitor charges. This is because the charge on the capacitor increases exponentially.

False --> The voltage across a capacitor in an RC circuit increases linearly during charging. This is because the voltage increases exponentially.

True --> One of the principal purposes of a capacitor is to store electric potential energy.

True --> A capacitor charges rapidly when connected to an RC circuit with a battery. This is because a cylindrical capacitor is basically a parallel plate capacitor rolled into a tube.

Describe how impacts between objects in the solar system have helped create notable features in the solar system such as craters
konstantin123 [22]
When 'The big bang' happened lots of large pieces of molten rock was flying around the solar system. As the rocks crashed together they got bigger and as the got bigger they attracted more rocks. Some scientists think that a large piece of molten rock hit the still developing Earth and created the Moon. This impact also caused the Earths angled spin. The Moon got trapped in Earth's orbit and has stayed ever since. Small astroids have hit the Moon causing craters. The Earth doesn't get hit as much because of our thicker atmosphere. Hope this helps!
