Answer:
Fnet = 12 N
Explanation:
Force on a point charge due to another point charge = kq1q2 / d^2
Force on +32uC = due to + 20uC + due to -60uC
where uC = 1 x 10^-6 C and k = 9 x 10^9 N m^2 / C^2
Net Force =
Fnet = 12 N
Answer:
The total distance at 7 s is:
Explanation:
<u>Distance due to the force</u>
We can use second Newton's law to find the acceleration.
Now, using the kinematic equation we will find the distance during this interval of time. Let's recall that the initial velocity is zero.
In the second part of the motion, the object moves at a constant velocity, as long as there is no friction between the object and the floor.
First, we need to find the final velocity of the first interval
So the second distance will be:
Therefore, the total distance is:

Uneven heating is what causes the temperature differences
<span>It's A. Individuals with traits NOT suited for survival DON'T pass their traits to their offspring, because they don't survive and they DON'T HAVE OFFSPRING. That's why, after a while, most of the living individuals have traits that ARE suited for survival. THAT's what evolution says. It says nothing about individuals changing. Note this not my answer its the answer of the guy up above who wrote it in the comments instead of in an answer!</span><span />
