What you’re doing is so easy pay attention more I think
I'm sorry, but this is not a question. What do you need to know?
Explanation:
The question is not complete, here is the complete question
<em>"Beatrice and the Elevator Beatrice, a middle school student, is visiting a very tall office building and notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is traveling down. After making these observations, Beatrice comes back to the building and stands on a bathroom scale that measures her weight as she travels up and down in the elevator.</em>
<em>1. . What question is Beatrice trying to answer?</em>
<em>2. What is one variable Beatrice could change in her investigation? What might she figure out if this
</em>
<em> variable was changed"</em>
1. Beatrice is trying to observe the influence of the elevator movement on her weight, Hence the question is<em> "will the elevator movement cause her weight to change"</em>
therefore moving upward the reading on the scale will increase
Reading=mg+ma
downward
Reading will reduce
Reading=mg-ma
2. The independent variable is the acceleration due to gravity g=9.81m/s^2
while the dependent variables are
i. The elevators acceleration
ii. Beatrice's mass

phone services can be compared through several characteristic. The rate of the
data transfer: the higher the rate the better the service, the availability-
the percent of the time the service is available (the greater the percent the
better the service) and the reliability, which means that the service is non
interrupted.</span>
Option (A) is correct. Fission and fusion reactions both involve making changes to an atom's nuclei.
Nuclear fission is a process in which a bigger nucleus breaks into two or more smaller nuclei with the liberation of large amount of energy.
Nuclear fusion is a process in which two smaller nuclei fuse together to form a bigger nucleus. A tremendous amount of energy is released during fusion.
Thus both fission and fusion involve the changes in the nuclei of atoms. Rest of the atom like the electronic configuration etc remains same.
