<h3><u>Answer;</u></h3>
It favors the movement of chloride ions from the inside to the outside of the cell.
<h3><u>Explanation;</u></h3>
- Electrochemical gradient refers to a gradient of electrochemical potential, normally for ions that can move across a membrane.
- Normally sodium (Na+) and chloride (Cl−) ions are at high concentrations in the extracellular region, and low concentrations in the intracellular regions.
- Assuming the chloride ions are equal on both sides of the membrane the electrochemical gradient for chloride ions favors the movement of chloride ions from the inside to the outside of the cell.
Answer:
v = 2.31 m/s
Explanation:
Kinetic energy will be converted partially into potential energy and rest will remain in the form of kinetic energy .
Initial kinetic energy = 1/2 mu²
u is initial velocity at the bottom .
Potential energy at the top
= mgh
Kinetic energy at the top
= 1/2 m v²
According to conservation of energy
1/2 mu² = mgh + 1/2 m v²
1/2 u² = gh + 1/2 v²
.5 x 4.5² = 9.8 x .76 + .5 v²
10.125 = 7.448 + .5 x v²
v = 2.31 m/s
Answer:
Amplitude
Explanation:
The amplitude is maximum height a wave is measured from its rest position.
Explanation:
The total distance in a path is called distance.
The shortest distance between two points is called displacement.
a) Here, the distance travelled between the park to your friend's house and back is
Distance between park to friends house + Distance from friend's house to your house.
b) Displacement would be the shortest distance between the park and your house.
a) Distance walked between your house to library and back is
Distance between your house and library + Distance between your house and library
b) Displacement would be zero (0) as the distance between you initial point and final point is zero. Here, the initial and final points are the same
