Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.
hope this helps have a nice day❤️
Explanation:
Answer:
ATP
Explanation:
We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.
AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.
Hope t help!
Answer:
Pressure, P = 28.2 kPa
Explanation:
Given that,
Number of moles, n = 0.54 mol
Volume of ideal gas, V = 35.5 L
Temperature, T = 223 K
We need to find the pressure of ideal gas. The equation of ideal gas is given by :
R is gas constant
P is pressure
So, the pressure of the gas is 28.2 kPa.
Blood flows through an artery that is partially blocked. as the blood moves from the wider region into the narrow region, alternately increases and then decreases.
<h3>What is the purpose of blood flow in heart?</h3>
The removal of positive charge by electrochemical gradients causes the membrane potential of the cell to shift more strongly in the direction of the equilibrium potential for potassium.
The membrane would become more negative as potassium permeability through the membrane increased. Given that potassium is a positively-charged ion and that the intracellular environment has a net negative charge, enhancing the membrane's permeability would result in a more negative membrane.
For instance, the amplitude of the potassium concentration gradient across the myocyte decreases as the external potassium level rises, lowering the resting membrane potential.
