A Particle (Charge 4

question 29

Multiple Choice

A particle (charge 4.0 µC) is released from rest at a point on the x- axis,x = 5.0 cm.It begins to move due to the presence of a 3.0-µC charge that remains fixed at the origin.What is the kinetic energy of the particle at the instant it passes the point x = 12 cm?

Definitions:

Light Compensation Point

The light intensity level at which the rate of photosynthesis equals the rate of respiration, leading to no net gain of energy by the plant.

Photosynthesis

The process by which green plants and some other organisms use sunlight to synthesize foods with carbon dioxide and water, producing oxygen as a byproduct.

Respiration

(1) Cellular respiration is the process by which cells generate ATP through a series of redox reactions. In aerobic cellular respiration, the terminal electron acceptor is molecular oxygen; in anaerobic cellular respiration, the terminal acceptor is an inorganic molecule other than oxygen. (2) Organismic respiration is the process of gas exchange between a complex animal and its environment, generally through a specialized respiratory surface, such as a lung or gill.

Calvin Cycle

A series of biochemical reactions taking place in the chloroplasts of photosynthetic organisms, part of the process of converting carbon dioxide and water into glucose, using ATP and NADPH produced in the light reactions of photosynthesis.
