Physics
A driver in a car traveling at a speed of 56.0 mi/h sees a deer 116 m away on the road. Calculate the minimum constant acceleration that is necessary for the car to stop without hitting the deer (assuming that the deer does not move in the meantime).

AP Chemistry
This is part of a marathon problem, we have to identify the five compunds of H, N, and O described below. For each compound, I have to write a Lewis structure that is consistent with the information given. a.) All the compunds are electrolytes, although not all of them are str...

What is the transfer mechanism of energy, momentum, and angular momentum?

gets larger?

suppose you have 2 cars, and the larger one is twice as massive as the smaller one. If you and a friend push on them so that their accelerations are equal, how must the forces applied to the cars compare? a. the force on the larger car is equal to that on the smaller car. b. t...

Suppose D=(w+2)(w-3)(w+6).For what three values of w will D have a value of 0?

Chemistry
If solution A had a pH of 8, and solution B had 1,000 times this hydrogen ion concentration what would be the pH of solution B, and would solution B be acidic or basic?
