The Sodium Pump Living cells actively "pump" positive sodium ions (Na+) from inside the cell to outside the cell. Th pumping because work must be done on the ions to move them from the negatively charged inner surface of the membrane to the positively charged outer surface A) Given that the electric potential is 6.4x102 V higher outside the cell than inside the cell, and that the cell membrane is 0.10 um thick, calculate the work that must be done (in joules) to move one sodium ion fronm inside the cell to outside. Express your answer using two significant figures B) If the thickness of the cell membrane is increased, does your answer to part A:? a) increase b) decrease c) stay the same

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?

A2.00-m long piano wire with a mass per unit length of 12.0 g/m is under a tension of 8.00 kn. what is the frequency of the fundamental mode of vibration of this wire?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
