No, because the gravitational constant is much smaller than the electrostatic constant. Answer A: No, because the gravitational constant is much smaller than the electrostatic constant. A No, because the gravitational force is only attractive, and the electrostatic force can also be repulsive. Answer B: No, because the gravitational force is only attractive, and the electrostatic force can also be repulsive. B Yes, because both forces have the same 1/ r2 dependence. Answer C: Yes, because both forces have the same 1/ , r, 2, dependence. C Yes, because the gravitational force always equals the electrostatic force at any given distance.

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
