Given that the electric potential is 7.3*10-2 V higher outside the cell than inside the cell, and that the cell membrane is 0.10 μm thick, calculate the work that must be done (in joules) to move one sodium ion from inside the cell to outside.

An object is moving forward along the ground. In order to change the object's direction, a force needs to act on the object. This force could be A. a push or pull forward. B. a push or pull downward. C. a push or pull to the right. D. all of these

What is the magnetic force acting on an electron if its speed is 3.0 * 106 meters/second and the direction is perpendicular to a magnetic field of 0.020 teslas? The value of q = - 1.6 * 10-19 coulombs.

Katya listed major questions that scientists try to answer when they classify organisms. Her list included the following questions: How many living things are there? What are the characteristics that define living things?

As a snowboarder descends a mountain slope, gravity, the normal force, and friction combine to exert a net force of 320 N in the downhill direction. The net force does 4700 J of work on her during one segment of her descent.
