Why must protons collide at such high speeds to fuse into deuterium?

Like charges repel. So to overcome the repulsive force protons do need high energy to perform work against the force of repulsion. Hence high speed

What is the resulting nucleus if a tritium and a deuterium nucleus fuse?
Helium and a neutron: D + T --> He + n + 17.59 MeV
What is the most common typle of nuclear fusion in the sun?
The most common fusion in the sun is two hydrogen atoms fusing to produce helium. There are different ways this can happen. Two deuterium atoms may fuse, or a deuterium atom may fuse with a tritium atom, or two tritium atoms may fuse. Since the half life of tritium is rather short, the overwhelming majority of these atoms are deuterium atoms. The commonest form of hydrogen, known as protium, does not take part in the process.
How does a brown dwarf compare to our sun?
The distinguishing feature is that a brown dwarf gets hot enough to fuse deuterium (hydrogen-2), but not hot enough to fuse hydrogen-1.
Where do the neutrons come from when hydrogen turns into helium in nuclear fusion?
In fusion engines we call stars, protons, which are hydrogen nuclei, are forced together and fused to create helium. This happens in early stellar life with the small- to medium-sized stars. When the protons are forced together, the first step involves fusing a pair of protons together with the weak interaction or weak nuclear force mediating the change of a proton into a neutron. Deuterium, or heavy hydrogen, is created. When deuterium reacts with a proton and the pair of particles are fused, a helium-3 nucleus is formed. From there, the reaction possibilities increase and we view what could occur along branches. This is the proton-proton chain reaction that is the basic process in stellar nucleosynthesis. The key to understanding these reactions is the knowledge of the ability of a proton to transform into a neutron through mediation by the weak nuclear force.
Is a particle accelerator used to accelerate particles at high speeds until the particles fuse together and create a new elements?
Not exactly.Accelerate particles to high speeds: yes.Create new elements: it is not new elements, but new particles that are created.Fuse together: this is not so much about particles fusing together; rather, the new particles are created from the energy of the impact. Remember that every energy has a mass equivalent. For example, the LHC is planned to increase its energy to 6.5 TeV per beam, meaning that two particles - two protons for example - will collide at a combined energy of 13 TeV. This corresponds to a mass of about 14,000 protons. This makes it possible to create new particles, including particles that are quite massive.
When is energy in the sun produced?
..particles (nuclei) fuse together to form heavier nuclei. Initially, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, lots of energy is released.

What occurs in a core of a star as the protons collide?
The atoms in the core of a star fuse together under the intense pressure, producing vast amounts of heat and energy.
What are elements the sun uses to produce energy?
Its mainly going to be Hydrogen nuclii. At the suns core, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, energy is released. Later on in the Stars life, fusion of the helium nuclii may take place a lot more often, as the preferred fuel of Hydrogen is depleted.
What converts hydrogen to helium in the sun?
The basic reactions: First 2 hydrogen nuclei (protons) fuse to form deuterium, a hydrogen isotope (1 proton, 1 neutron). Deuterium then fuses with another proton to form a light helium isotope, helium3 (2 protons, 1 neutron. 2 helium3 nuclei fuse to form Helium4 (2 protons 2 neutrons), + 2 hydrogen nuclei (protons).
What prevents two protons from combining?
the electromagnetic repulsion. they are both positively charged particles, and just like putting the south ends of a magnet together, they are actually repelled. what stops them from flying apart is the strong nuclear force. gravity is also an attractive force between them yet it is so weak that it is negligible when being compared to the electromagnetic repulsion.
