Answer:
force of the breaks is 6650 N, direction opposite to direction of movement
Explanation:
Answer: If a positively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be directed OUTWARD. Thus, the equilibrium potential for this ion would be POSITIVELY charged. The correct answer is OUTWARD: POSITIVELY.
Explanation: Usually across a cell membrane there is a force that acts on it which is as a result of unequal distribution of charges. This force is known as electrochemical driving force. It is determined by the difference between the membrane potential ( that is, the electrical potential difference across the cell membrane) and the ion equilibrium potential. The membrane potential of a cell helps in signal transmission between different parts of the cell and results when there is unequal distribution across the cell.
Therefore If a positively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be directed outward.Thus, the equilibrium potential for this ion would be positively charged.
It has increased. More kinetic energy increases the opposing force.
KE = 1/2mv^2
1. Find velocity:
8.0 + 6.1 = 14.1 m/s
2. Plug and Chug
KE = 1/2mv^2
KE = 1/2(75g)(14.1 m/s)^2
KE = 7,455.375 Joules
