Explanation:
a.)
We find the relative speed
u = vb + vc
b.)
chuck and the cart are at a rest position
m<em>cart</em>vc = <em>mball</em>vb
from part a above,
vc = u - vb
mcartu = vb(mcart + mball)
make vb the subject of the equation
c.)
from anser a,
vb = u - vc
then mcart vc = mball(u-vc)
d.
Mballvb = (Mcart + Mball)vj
we make vj the subject to get her relative speed
e.
given the solution in part d above,
we have
remember,
vb = u - vc
such that
thank you!
In this case you have 3 Oxygen.
Consider that H is hydrogen and doesn't have a number on its side so is 1.
N is nitrogen and as well as hydrogen doesn't have a number on its side so is also 1. On the other hand, O oxygen does have a number which is 3. Which means that to make Nitric Acid you need 1 hydrogen, 1 nitrogen and 3 oxygen.
If the number where to be on the left side of the thing and <span>teh</span> start mostly <span>then</span> that would mean that there are the # atoms of nitric Acid... Hope it help :3
Answer:
Preoperational
Explanation:
According to Piaget's theory of cognitive development, the preoperational stage is the second stage. This stage includes children between the age group of 2 to 7 years. Children can understand conservation tasks and learn to manipulate various symbols during this stage.
So, the answer is the preoperational stage.
