Answer:
24 kgm/s
Explanation:
Momentum (p) = mass x velocity
Mass = 3kg , velocity 8m/s
momentum (p) = 3kg x 8m/s
= 24kgm/s
Particle-A is an electron, racing around in a cloud that's far from the nucleus.
Particle-B is either a proton or a neutron, in the nucleus.
The big clue is where you said that particle-A has very little mass
compared to particle-B. Protons and neutrons have almost identical
masses, but it's the same mass as more than 1,800 electrons !
Answer:
These planets rotate around the sun in a circular path. Likewise in a heliocentric model it is believed that the sun is at the center of the universe and the planet earth along with all other planet move around it. Thus in both geocentric model and heliocentric model bodies in space move in circular orbits.
