Which statement is true of an alpha particle? A. It is a particle that travels at the speed of light.
B. It is an electron.
C. It is the largest decay particle.
O
D. It is electromagnetic radiation, not a true particle.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
