Answer:

Antimatter is

molecules formed by atoms consisting of antiprotons, antineutrons, and positrons. Stable antimatter does not appear to exist in our universe.

A antimatter is particle physics, antimatter is a material composed of the antiparticle "partners" to the corresponding particles of ordinary matter. A particle and its antiparticle have the same mass as one another, but opposite electric charge and other quantum numbers.

Two protons, starting several meters apart, are aimed directly at each other with speeds of 2.00 * 105 m>s, measured relative
victus00 [196]

Explanation:

Since, the two protons are at the initial state of point a and point b. Hence, total mechanical energy at point a and point b is as follows.

           U_{a} + K_{a} = U_{b} + K_{b}

or,           K_{a} = U_{b}  

where,   K_{a} = kinetic energy of two protons

So,      2(\frac{1}{2}mV^{2}_{a}) = \frac{1}{4 \pi \epsilon_{o}} \frac{|e|^{2}}{r_{b}}

       r_{b} = \frac{1}{4 \pi \epsilon_{o}} \frac{e^{2}}{mV^{2}_{a}}

Putting the given values into the above formula we will calculate the value of r_{b} as follows.

      r_{b} = \frac{1}{4 \pi \epsilon_{o}} \frac{e^{2}}{mV^{2}_{a}}

                = (9.0 \times 10^{9} Nm^{2}/C^{2} \frac{(1.602 \times 10^{-19}^{2} C}{1.67 \times 10^{-27} kg \times 2 \times 10^{5}}

                = 3.45 \times 10^{-12} m

Now, we will calculate the maximum electric field as follows.

      F = \frac{1}{4 \pi \epsilon_{o}} \frac{|e|^{2}}{r^{2}_{b}}

         = 9.0 \times 10^{9} Nm^{2}/C^{2} \frac{(1.602 \times 10^{-19}C)^{2}}{3.45 \times 10^{-12}}

         = 0.194 \times 10^{-4} N

Therefore, we can conclude that the maximum electric force that these protons will exert on each other is 0.194 \times 10^{-4} N.

In the earth-moon system the moon orbits the earth. What is the "centripetal" force causing the moon to stay in orbit around the
gavmur [86]

The centripetal force is the gravitational force of attraction between the Earth and the Moon.

Also, the gravitational force of attraction between the Earth and the Sun is the centripetal force that causes the Earth to stay in orbit around the Sun.

Also, the gravitational force of attraction between a TV satellite, a weather satellite, or a GPS satellite and the Earth is the centripetal force that causes each satellite to stay in orbit around the Earth.
