Answer to Problem 1QAP

False

Explanation of Solution

The basic environmental requirement of life is the presence of atmosphere, abundant surface water that is drinkable, combination of surface pressure and temperature and some set of chemical elements from which cells are formed.

The four basic chemical elements that make up 96% mass of living organism are oxygen, hydrogen, carbon, and nitrogen and the presence of these elements is a basic requirement for life in general. All chemical elements except hydrogen and helium were produced by stars. Therefore they are present everywhere.

One more important requirement is the presence of these elements in molecules that are used as building blocks of life; most of the organic molecules are created by some chemical reactions in the presence of water. Water acts as a solvent in most of the organic reactions.

Conclusion:

Thus, Water is the essential component for life to begin so self-replicating molecule cannot begin a life alone. Hence the above statement is false.

4B. Four electrons are located on the corners of a square, one on each corner, with the sides of the square being 25 cm long. a) Draw a sketch of the scenario and use your sketch to b)  Determine the total force (magnitude and direction) on one of the electrons from the other three?
Portfolio Problem 3. A ball is thrown vertically upwards with a speed vo from the floor of a room of height h. It hits the ceiling and then returns to the floor, from which it rebounds, managing just to hit the ceiling a second time. Assume that the coefficient of restitution between the ball and the floor, e, is equal to that between the ball and the ceiling. Compute e.
Portfolio Problem 4. Consider two identical springs, each with natural length and spring constant k, attached to a horizontal frame at distance 2l apart. Their free ends are attached to the same particle of mass m, which is hanging under gravity. Let z denote the vertical displacement of the particle from the hori- zontal frame, so that z < 0 when the particle is below the frame, as shown in the figure. The particle has zero horizontal velocity, so that the motion is one dimensional along z. 000000 0 eeeeee (a) Show that the total force acting on the particle is X F-mg k-2kz 1 (1. l k. (b) Find the potential energy U(x, y, z) of the system such that U x = : 0. = O when (c) The particle is pulled down until the springs are each of length 3l, and then released. Find the velocity of the particle when it crosses z = 0.
