A nucleus of Uranium-238 (m = 3.95292599x10^-25 kg) ejects an alpha particle (m = 6.64465675x10^-27 kg), transmuting into a nucleus of Thorium-234 (m = 3.88638509x10^-25 kg).
If the alpha particle is ejected to the right at 1.443x10^7m/s, determine the magnitude of the velocity
of the nucleus as it recoils to the left.
V= ? •105 m/s to the left

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
