CASE STUDY On planet Betatron, mass is measured in bloobits and length in bots. You are the Earth representative on the interplanetary commission for unit conversions and find that 1 kg = 0.23 bloobits and 1 m = 1.41 bots. Express the density of a raisin (2 103 kg/m3) in Betatron units.
Momentum (p) is a quantity with unit kgms−1 . It is thought to be related to the mass (m) and velocity (v) of a particle. Use dimensional analysis to find the relationship among p, m and v.
When a particle decays, it splits into two different particles and each is shot off in opposite direction. The speed of each particle is such that momentum is conserved. uranium 238 decays into thorium 234 by emitting an alpha particle (helium 4). If the alpha particle leaves with a speed of 6.8 x 10^3 m/s, what is the speed of the thorium atom? Give your answer in m/s to three significant figures. Use atomic mass units for the mass of each particle. Uranium 238 in atomic mass units is 238 to three significant figures.
In this problem we will observe how the momentum of an electron changes as its velocity approaches the speed of light. The mass of an electron is 9.109 × 10-31 kg Part (a) First, what is the momentum of an electron which is moving at the speed of a car on a highway, say 31 m/s, in kilogram meters per second? Part (b) What is the momentum of an electron moving at 18 % of the speed of light, in kilogram meters per second?
