If the IMA of a machine is 4 and the effort force is 6.0 newtons, then the force exerted on the resistance by the machine is D-24 N
Answer:
a. Remaining at rest requires the use of ATP.
Explanation:
The resting membrane potential is maintained by the sodium-potassium pump. The sodium potassium pump does this by actively pumping sodium ions out of the cell and potassium ions inside the cell in a ratio of 3:2. This movement of ions by the sodium-potassium pump is against their concentration gradient. In a neuron at rest, there are more sodium ions outside the cell than there are inside the cell. Also, there are are more potassium ions inside the cell than there are outside the cell. However, there are ion channels through which these ions enter and leave the cell. Sodium ion channels allow sodium to enter the cell following its concentration gradient, whereas, potassium ion channels allow potassium to leave the cell following its concentration gradient. However, more potassium ions leave the cell than do sodium ions enter the cell because of the higher permeability of the cell to potassium ions.
In order to maintain the resting membrane potential, the sodium potassium pump powered by the hydrolysis of an ATP molecules pumps sodium ions out of the cell and potassium ions into the cell.
<em>Therefore, the correct option is A, as ATP is needed by the sodium-potassium pump in order to maintain the resting membrane potential.</em>
They discovered that *elements* show increase in atomic numbers across the period.
Answer:
Shinkansen this a bullet train are very high speed trains in Japan. The disaster was nearly saved to occur with legitimate and successful administration. On 11 December, a split was found in a train which was around 14 cm long. It is said that had it been 17 cm, the train could have been crashed and along these lines the calamity didn't happen just by 3 cm.
It was a five hour journey meanwhile a intern who was selling something seen an odd smell and conversed with the conductor about it. At long last it was explored and they additionally saw a bizarre sound at a station while boarding. at the point when the architects explored, they chose to proceed with the voyage saying everything is ordinary. At last the train halted at Nagoya station where the break was watched obviously. It additionally had sensors that could identify it
In spite of the fact that they halted before the break could turn out to be huge, if wrecking had happened, it could have caused gigantic devastation. Till now, the makers asserted that slug trains have zero percent plausibility to confront any mishap however this episode opened the eyes of all.
Explanation:
Answer:
Well he couldn't be pushed back as there isn't a place for him to float back, because of Newton's third law: Every force has an opposite force when Eugene pushes, he will float backwards
Explanation:
Hope this helps!
