Parts D, and E ** 25. A n*, initially at rest, decays by way of the reaction n* = a* + x, where x is an unknownparticle. From a bubble chamber (a way to measure the velocity of charged particles), it isfound that the momentum of the a* is 29.792 MeV (this is momentum in energy units, thatis, it is the product pc). For this problem, you will need more accurate masses than given inTable 26.2. More accurate values are m = 139.570 MeV and m, = 105.658 MeV. [Hint: Keepall calculations accurate to the nearest 0.001 MeV.]%Da) Find the total energy of the u* after the decay.b) Use energy conservation to find the energy of the unknown particle.c) Use momentum conservation to find the momentum (pc) of the unknown particle.d) Find the mass of the unknown particle.e) Based on your mass result, and on other conservation laws, explain what you thinkthe particle might be.

The mass of the unknown particle can be calculated using the conservation laws

Which of the following are true statements about velocity, acceleration, and force? (More than one answer) A All three of these quantities are vectors. B Force always causes velocity to increase. C Acceleration always causes velocity to increase. D Acceleration is a change in force per unit time. E Force and acceleration are related by a law of nature; acceleration and change in velocity are related by a definition. F Velocity is not a vector, but force and acceleration are vectors. G Force = mass times velocity H Acceleration and net force are always in the same direction, but velocity can be in any relative direction to those. I Force and acceleration are related via mass. J Newton's Second Law of Motion says that: acceleration = mass times force
