Nebula - protostar - main sequence star. The hydrogen gas in the nebula is pulled together by gravity and it begins to spin and
andrezito [222]

Answer:

The mass of a star determines its life cycle, that is, more the mass, shorter will be its life cycle. The mass of the star is determined by the concentration of matter, which is found within its nebula. In the nebula, with time, the hydrogen gas comes in close proximity with each other due to gravity and starts to spin.  

With the brisk spinning, the gas heats up and turns into a protostar. The temperature now reaches 15,000,000 degrees and within the core of the cloud, the phenomenon of nuclear fusion takes place. The cloud now contracts a little, starts to glow brightly, and turns stable. The cloud now becomes a prime sequence star, and will stay in this phase for millions of years, the Sun of our galaxy is in this stage at the moment.

Under certain circumstances, potassium ions ( K + ) in a cell will move across the cell membrane from the inside to the outside.
dexar [7]

Answer:

8.18 × 10 ⁻²¹.

Explanation:

The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.

The change in the potential energy can be calculated as follows:

W = v2-v1 × q.

Here, the charge of the proton is considered because k+ ions has been used.

W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.

W= 8.18 × 10 ⁻²¹J.

Thus, the answer is 8.18 × 10 ⁻²¹.
