By tracking the midpoint of the line joining the stars weighted by mass
By counting pulses

Question 2342

▼

What determines the direction of motion of decay products in the lab frame?

Temperature
Color of particles
Conservation of momentum and initial motion
Magnetic field

Question 2343

▼

In a two-body decay with unequal masses, how do their speeds compare in the CM frame?

Both move at same speed
Heavier moves faster

Speeds are unrelated

Question 2344

▼

Why is the center of mass frame preferred in particle physics experiments?

It increases speed
It reduces particle mass
It simplifies the analysis of collision and decay products
It stops time

Question 2345

▼
