Suppose we have two positively charged particles a distance of 4 m apart from each other. Particle 1 has a charge of 6 C and particle 2 has a charge of 1.3 x 10^3 C. What amount of
electrostatic force exists between these two particles?
4.35 x 10^12 N
1.75 x 10^13 N
6.5 x 10^2 N (aka 650 N)

Apassenger walks toward the rear of a moving train. describe her motion as seen from a reference point on the train. then describe it from a reference point on the ground

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
