A9.5 v battery supplies a 2.0 ma current to a circuit for 6.0 h . you may want to review (page) . for with math skills, you may want to review: conversion between seconds and hours part a how much charge has been transferred from the negative to the positive terminal

= 43.2 Coulombs

Explanation:

Using the formula;

Q = it

where Q is the charge in coulombs

I is the current in Amperes and

t is the time is seconds

I = 2.0 mA = 0.002 A

t = 6.0 h = 6 × 3600 seconds

Therefore;

Q = 0.002 × 6 × 3600 s

   = 43.2 Coulombs

Therefore the charge that has been transferred from the negative to the positive terminal is 43.2 coulombs.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
