Answer:
Usually when climbing, it's best to be in the small front ring and the largest back ring. If your cadence is about 100 rpm, then whatever gear you're in is fine. It depends on the road, but as long as your pedaling is at a level you're comfortable with, you're fine.

Google answer by the way.
The answer is C .Y on the chart. im 100% its right . hope this helps .
Ca (NO3)2(s) ---> Ca2 + (aq) + 2NO3 -(aq)
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
Solids - particles are close together in a regular structure and vibrate about fixed positions
liquids - particles are close together but free to move past each other randomly
gases - particles are far apart and move randomly in all directions
The density of a substance changes when it changes state. Its mass does not change. This is because its particles do not disappear - they are just rearranged and occupy a different volume.
