Scientfic notation 1.063 x 10^2
Answer:
C
Explanation:
When A and B come in contact with each other, +12 - 12 = 0 so their changes cancel.
Now C has a charge of +12
When A and C come together they each have an equal share of that 12, so each of them has 6
So the answer is
A B C
6 0 6
which is C
An element is a pure substance made of atoms that are all of the same type.
Answer:
Number 6:
• From the formula of force:
![force = mass \times acceleration \\ { \boxed{f = ma}}](https://tex.z-dn.net/?f=force%20%3D%20mass%20%5Ctimes%20acceleration%20%5C%5C%20%7B%20%5Cboxed%7Bf%20%3D%20ma%7D%7D)
• But we need to get the acceleration, from the first newtons equation of motion
![v = u + at](https://tex.z-dn.net/?f=v%20%3D%20u%20%2B%20at)
• v is the final velocity, but v is zero because the bullet came to rest.
• u is the initial velocity, u = 350 m/s
• a is the acceleration that we need
• t is the time, t = 0.0018 seconds.
» let's now substitute:
![0 = 350 + (a \times 0.0018) \\ 0.0018a = - 350 \\a = - 194444.44 \\ { \underline{ \: \: |a| = 194444.44 \: m {s}^{ - 2} }}](https://tex.z-dn.net/?f=0%20%3D%20350%20%2B%20%28a%20%5Ctimes%200.0018%29%20%5C%5C%200.0018a%20%3D%20%20-%20350%20%5C%5Ca%20%3D%20%20-%20194444.44%20%5C%5C%20%20%7B%20%5Cunderline%7B%20%5C%3A%20%20%5C%3A%20%20%7Ca%7C%20%20%3D%20%20194444.44%20%5C%3A%20m%20%7Bs%7D%5E%7B%20-%202%7D%20%7D%7D)
[ negative shows retârdation or deceleration or decrease in speed ]
• Therefore, let's find the force:
mass = 6g = (6/1000) kg = 0.006 kg
![force = m \times |a| \\ f = 0.006 \times 194444.44 \\ { \underline{ \underline{ \: \: force = 1166.67 \: \: { \sf{newtons \: \: }}}}}](https://tex.z-dn.net/?f=force%20%3D%20m%20%5Ctimes%20%20%7Ca%7C%20%20%5C%5C%20f%20%3D%200.006%20%5Ctimes%20194444.44%20%5C%5C%20%7B%20%5Cunderline%7B%20%5Cunderline%7B%20%5C%3A%20%20%5C%3A%20force%20%3D%201166.67%20%5C%3A%20%20%5C%3A%20%7B%20%5Csf%7Bnewtons%20%5C%3A%20%20%5C%3A%20%7D%7D%7D%7D%7D)
