D. be transported from place to place
because it does allow c to happen but not directly as it would have to go through condensation first.
When the water is evaporated in the air it can be moved from place to place by the wind.
Almost anything that isn't a metal. Rubber, pure water, wood, and plastic, are all good answers.
Answer:
B yes when displacement is negative
When there is no air resistance, objects of different masses dropped from rest:
a.
fall with equal accelerations and with equal displacements.
Answer:
Explanation:
Potential energy of a pair of charges
= k q₁q₂ /r₁₂
At r₁₂ = .125 m
= - 9 x 10⁹ x 2.4 x 4.3 x 10⁻¹² / .125
= - 743 x 10⁻³J
At r₁₂ = √2 x .275 m
- 9 x 10⁹ x 2.4 x 4.3 x 10⁻¹² / √2 x .275
= - 238.85 x 10⁻³J
= 239 x 10⁻³ J
Change = - 238.85 x 10⁻³ +743 x 10⁻³
= 504.15 x 10⁻³ J
B )
Work done by electric force will be same but in negative sign
= - 504.15 x 10⁻³ J
= - 504 x 10⁻³ J
