The answer would be Matter
Answer:
it has three atoms of hydrogen on each side.
Explanation:
it must be equal on both sides and answer D. is the most specific
Answer:
s=0.36m part c lands
Explanation:
from conservation of linear momentum
we know that
the momentum before Collision(explosion) is equal to the momentum after collision( explosion)
0=maua+mbub+mcuc
ma=.5kg
mb=.5kg
mc=9.8-(0.5+0.5)
mc=8.8kg
since the fragments all fall to the ground at the same time, we assume same time for all
t=0.27s
the velocity of a
v=u +at
since it falling stariaght down
v=0+9.81*.27
v=2.64m/s is the vertical side of its velocity
, since its falling straight down , the horizontal velocity is zero
the velocity of b
s=ut horizontal component of the distance
6.5=.27*ub
ub=24.07m/s
from
0=maua+mbub+mcuc
0=0.5*0+0.5*24.07+8.8*cu
uc=1.36
the distance from a will be
s=ut
s=1.36*.27
s=0.36m
