What is the sequence of the energy transformations that occur in a nuclear reactor

Answers

Answer 1
Answer: Nuclear reactors use uranium, consisting of solid ceramic pellets. The uranium atoms split through the process of fission which produces heat energy. Nuclear power plants obtains the heat needed to form steam that rotates the turbine to produce electrical energy which is being distributed to houses wherein electrical energy is utilized to different appliances.

Look at Figure 2. Describe the motion of the object in Graph ACompare Graphs A and B in Figure 2. At a time of 2 seconds, which graph shows a greater velocity? How do you know?

Answers

The graphs show distance versus time data. For graph A, we can say that velocity is constant until it reaches time of 8 seconds. And a constant velocity is again exhibited starting at time 12 seconds. For graph B, the velocity is changing as time pass by since  the slope is changing. At time of 2 seconds, graph A has greater velocity since it has a steeper slope.

Answers

The answer is current.

Current in the context of an electrical circuit is the flow of charge. Current is a quantity that is physical and can be measured. Current is defined as the rate of the flow charge past a certain point in a circuit. Current is expressed in Amperes which is equal to 1 coulomb/1second.

What is produced when calcium reacts with fluorine in a synthesis reaction? Ca + F2 →

Answers

When calcium reacts with fluorine in a synthesis reaction, calcium fluoride or CaF2 is produced. This compound is a colorless, powdery, and insoluble substance. It is used as a coating in a wide variety of industries such as the windows and lenses industries. Also, it is used in different thermal imaging equipment, spectroscopy, and lasers because of its transparency.

Jake drops a book out of a window from a height of 10 meters. At what velocity does the book hit the ground? Answer choices: A: 7.0Meters/Second B: 10Meters/Second C: 14Meters/Second D: 28Meters/Second

Answers

Jake drops a book out of a window from a height of 10 meters. The velocity does the book hit the ground is 14 m/s. hence option C is correct.  

What is velocity?

Velocity is defined as the pace at which an item changes position while moving in one direction, as seen from a certain point of view and as measured by a specific unit of time. Given that it has both a magnitude and a direction, velocity is a vector quantity.  Velocity measures movement that begins in one location and moves to another location.

We are aware that V=final velocity and V2-U2=2.

U is the initial velocity, and A is the acceleration, and D is the distance, therefore V=14 m/s.

Thus, Jake drops a book out of a window from a height of 10 meters. The velocity does the book hit the ground is 14 m/s. hence option C is correct.

#SPJ2
C is your answer. we know V^2-U^2=2 as where V=final velocity.
U is inital velocity
A= acc.
s= distence
a.t.q
v^2 -o^2 =(2*9.8*1o)
so, V=14 m/s
