Object a attracts objects with a gravitational force of 5 newtons from a given distance. if the distance between the two objects is reduced in
half, what will be the changed force of attraction between them?
a 2.5 newtons
b. 10 newtons
c 15 newtons
d. 20 newtons
e 25 newtons

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

Wow good luck with that answer

At maximum height, kinetic energy is converted in potential energy  formula: at max height, ke = ½ * 0.27kg * (16m/s) ² = 34.56 j  so the remaining pe = (41.70 – 34.56)= 7.14 j = 0.27 kg * 9.8m/s² * h  = (9.8/7.14 * 0.27)so max height h = 5.08 or 5 m 

Following the american gauge wire standards ,the larger gauge number, the slimmer the wire and thus the smaller current carrying capacity it can have.then both statements would be incorrect, as they are saying the opposite of what it is actually is.(smaller gauge numbers have thicker wires and can carry more current)
