<span>The answer is A. high pressure. The fusion of two deuterium nuclei can only be done with high temperature and also highpressure to prevent electrostatic repulsion of the proton. The successful combination of the deuterium then creates helium as it all combines.

Answer:
Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.
Let us consider the centripetal force equation,
centripetal force F = mv² / r
f= force
v= velocity
m= mass
r= radius.
in all the factors only velocity has the power of 2. so when you double the velocity then it will become square of that.
if v= 2v , F = m4v² / r
so velocity is doubled it would produce the greatest change in the centripetal force.
A piece of DNA from the parent to the offspring.
For example when you were born you're mum transferred some of her traits (hair color, personality ect.) on to you. Same with your dad. So you might look like your dad but have the same personality as your mum.
