Neutrons have a mass of 1.675×10 to the negative 27th. determine the kinetic energy of a neutron traveling 20. 5% of the speed of light

The K.E of the neutron is, K.E = 5.025 x 10⁻²⁰ J

Explanation:

Given data,

The mass of the neutron, m = 1.675 x 10⁻²⁷ kg

The velocity of the neutron, v = 20.5% of c

The speed of light, c = 3 x 10⁸ m/s

                                    v = 20.5% of c

                                       = 3 x 10⁸ x 20 / 100

                                       = 6 x 10⁷ m/s

The K.E of the neutron is,

                              K.E = ½ mv²

                                     = ½ x 1.675 x 10⁻²⁷ x 6 x 10⁷

                                      = 5.025 x 10⁻²⁰ J

Hence, the K.E of the neutron is, K.E = 5.025 x 10⁻²⁰ J

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

b.transmitters send radio waves, and receivers capture radio waves.
