Calculate the electric force that exists between two objects that are 0.900 m
apart and carry charges of 0.00150 c and 0.00340 c. is this force attractive or
repulsive?

answer:

the electric force is 4,08e-5 joules

explanation:

we use the formula

e= 1/2 x q x v   , q being the charge stored in each capacitor plate and v the voltage applied to the plates

e =1/2 x (3,4 e-6 c) x (24 v) = 4,08 x-5 j

the unit joule equals coulomb x volt

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
