Rank the charge density at each labeled point a -e, greatest first. (note that point e indicates the left side of sphere 3; there is no labeled point on the right side of sphere 3.) rank positive charge greater than negative charge. include zero in your ranking. hint: image what would happen is sphere 1 were removed; then, consider what effect sphere 1 has on spheres 2 and 3 when it is present.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.

If a person whirls an object horizontally in a counter clockwise direction and the string breaks at point p as shown, what path will the rock follow?
