Question 10 A balloon with a charge of -6.67 x 10-6 C is brought near a metal rod with a
charge of -5.27 x 10-8 C. They are separated by a distance of 0.43 m.
a) What is the electrical force acting on them? (round your answer to the
nearest ten thousandths place, for example 0.1234 or -0.1234)
Please help me

The rocks expand when there hot/warm  and contract when they are cold.

When you go to ask a qustion there will be a picture of a paper clip looking thing and then it will pop up your files and you click on the imajes and then you up load it

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

It would stay the same
