Aline of a -25 mc uniformly distributed charge extends from the y 0.0 m to y 8.0 m a) at the (x, v) coordinate (4.0 m, 4.0 m), what is the electric potential due to the distribution of charge? (assume that the electric potential 0 at a point an infinite distance away from the origin.) b) what is the electric potential at (2.0m, 3.0m)? for the last part of this problem, let there be four lines of charge, each 8.0 m long with a uniformly distributed charge of -100 mc (total). these lines are put in a plane forming a square with coners at (om, om), (8m, om), (8m, 8m), (om, 8m). c) what is the electric potential at the center of the square?

Alarge box of mass m is pulled across a horizontal frictionless surface by a horizontal rope with tension t. a small box of mass m sits on top of the large box. the coefficients of static and

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
