Answer:
a light ray will always A light ray will always reflect away from a surface at an angle equal to the angle at which it struck the surface
Explanation:
it sound more formal and just plainly better
KE = mv²/2
m=2*KE/v²
v=50 m/s
KE=500J
m=2*KE/v² =2*500/50²=1000/2500= 0.4 kg
m/s² aka meter per second squared.
acceleration = change in velocity/time
= distance/time
--
time
= m/s
--
s
=m/s^2
M(Mn(ClO3)3)=(54.938)+(35.45x3)+(15.999x9)
M(Mn(ClO3)3)=305.279 g/mol
