is. light from the lamp reaches the person via two paths. it
strikesthe mirror at a 30.0 degree angle of incidence and reflects
from itbefore reaching the person. it also travels directly to the

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
