Which statement correctly compares nuclear fission with nuclear fusion?
A. Nuclear fission forms a larger nucleus, and nuclear fusion forms
smaller nuclei.
B. Nuclear fission uses a common isotope, and nuclear fusion uses a
rare isotope.
C. Nuclear fission reactions demonstrate the conservation of atomic
number, and nuclear fusion reactions do not.
D. Both nuclear fission and nuclear fusion produce energy from
matter
Help please
Answer:
Both nuclear fission and nuclear fusion produce energy from
matter
:D
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
What is nuclear fusion?The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.
The more energy it takes to liberate an electron from a smaller atom. This is referred to as binding energy.
As a result, when two little nuclei fuse together, there is more binding energy than when two big nuclei fuse together.
For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
Hence option D is correct.

How do positive and negative acceleration differ?
Positive acceleration represents an object speeding up; negative acceleration represents an object slowing down.
Positive acceleration moves north or east; negative acceleration moves south or west.
Positive acceleration occurs when there is more velocity than speed; negative acceleration occurs when there is less velocity than speed.
Positive acceleration occurs when an object changes its speed but not its direction; negative acceleration occurs when an object changes both its speed and direction.
Answer:
acceleration
Explanation:
acceleration determines whether you will be adding to or subtracting from the velocity. while negative acceleration means you will subtract from the current value of the velocity and a positive acceleration means you will add

If the current in a wire which is placed perpendicular to a magnetic field increases the force on the wire
Answer:
The force on the wire increases
Explanation:
Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.
Given that the magnetic field and the wire are perpendicular, Ф = 90°
So, F = BILsin90° = BIL
Since B and L are constant, F ∝ I
So, if the current in the wire increases, the force on the wire also increases.

You cannot classify matter based on chemical properties. true or false?
Answer:
ture i think
Explanation:
It is false that one cannot classify matter based on chemical properties.
What is a matter?Matter is the scientific term for any type of material. Matter is defined as anything with mass that occupies space.
Matter requires at least one subatomic particle, though most matter is made up of atoms. A pure substance is sometimes referred to as matter.
Solids, liquids, and gases are the three forms or phases of matter. A substance is defined as matter that is homogeneous and has identical parts.
Substances are classified as either elements or compounds. Elements are pure substances that cannot be chemically decomposed into simpler substances.
Chemically, matter can be classified as pure substance elements and compounds, mixture, or impure substance.
Thus, the given statement is false.

You just earned a $1000 bonus at your job. Would you rather receive all the money at the end of the
year or half the money now and half the money later? Why?
A 100 N force is applied to move an object a horizontal distance of 5 meters at constant speed in 10 seconds. How much power is done?
The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W
We'll begin by calculating the energy. This can be obtained as follow:
Force (F) = 100 N
Distance (s) = 5 m
Energy (E) =?E = F × s
E = 100 × 5
E = 500 JFinally, we shall determine the power. This can be obtained as follow:
Energy (E) = 500 J
Time (t) = 10 s
Power (P) =?[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]
P = 50 WTherefore, the power used in moving the object is 50 W.

10. A jogger runs along a road for a distance of 2700 m. If it takes her 900 seconds
to run that distance, what is her speed?
Answer:
Speed = 3 m/s
Explanation:
Given the following data;
Distance = 2700m
Time = 900 s
To find the speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting into the equation, we have;
[tex]Speed = \frac{2700}{900}[/tex]
Speed = 3 m/s

calculate the magnitude of distance and displacement of a body moving in a complete circle
Answer:
Total distance = 2πr
Total displacement = 0
Explanation:
To Calculate the magnitude of distance and displacement of a body moving in a complete circle, we must come to these facts that:
The distance = circumference of the circle which is equal to the product of 2 ,pi and radius r
That is
Circumference = 2πr
Since velocity is changing and not constant, it is a vector quantity. Likewise displacement is a vector quantity.
The total displacement will be equal to zero.
Therefore, total distance is equal to the circumference of a circle while total displacement is equal to zero.

There are some ways objects in motion are affected. _______________, or pushes and pulls, affect the motion of an object. _______________ is a force that pulls objects down to Earth. _______________ is a force that slows things down or can even make them stop. Did you know acceleration means more than the increase of an object’s speed? It also describes an object that is slowing down or changing _______________. Since acceleration is a change in speed or direction, that means, _______________ is a change in velocity
Answer:
Forces, Gravity, Friction, Direction, Acceleration.
The answers for the fill-in-the-blanks would be Force, gravity friction
direction and acceleration respectively.
What is gravity?It can be defined as the force by which a body attracts another body towards its center as the result of the gravitational pull of one body and another,
There are a few ways that moving objects are impacted. Pushes and pulls, or force, have an impact on how an object moves.
The force of gravity drags items toward the Earth.
Friction is a force that causes objects to move more slowly or even come to a stop.
It also applies to an item that is reversing course or slowing down. Since acceleration is a change in velocity, it can also be a change in speed or direction.
Thus, Force, gravity friction direction, and acceleration are the answers respectively.
