The statement 'in a linear relationship, a change in one variable will always result in a change of the same size in the other variable' is FALSE.
What is a linear relationship?A linear relationship is a type of association between two variables where a change in one produces a direct modification in the another one.
A linear relationship may change depending on the rate of change and therefore the size of this variation is not the same.
In conclusion, the statement 'in a linear relationship, a change in one variable will always result in a change of the same size in the other variable' is FALSE.

The diagram below shows a light ray striking a plane mirror surface at an angle of 40° to the normal. Which of the following diagrams shows the ray that is reflected from the plane mirror surface?
Answer:
3rd diagram
Explanation:
From the laws of reflection, we understood that the angle of incidence in equal to the angle of reflection.
For example, if a ray of light strikes a mirror at 60°, it reflected at the same angle (i.e 60°)
Considering the diagram given in the question above,
The ray of light strikes the mirror at 40°. Therefore, the light will be reflected with the same angle (i.e 40°)
Thus, the 3rd diagram gives the correct answer to the question.
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?
Answer:
50 W
Explanation:
Given :Force applied = 100 NDistance covered = 5 metresTime = 10 secondsTo find :
Power
Solution :For calculating power, we first need to know about the work done.
[tex] \bf \boxed{Work = Force \times displacement} [/tex]
Now, substituting values in the above formula;
Work = 100 × 5
= 500 Nm or 500 J
We know that,
[tex]\bf \boxed{Power=\dfrac{Work\:done}{Time\: taken}}[/tex]
Substituting values in above formula;
Power = 500/ 10
= 50 Nm/s or 50 W
Hence, power = 50 W .

A marathon runner runs a 200m sprint in 10 seconds. It is known that he started standing still. Then determine the acceleration achieved by him knowing that his final speed was 36 km / h.
Answer:
The acceleration of the runner is 0.25 m/s²
Explanation:
Given;
distance covered by the runner, d = 200 m
time of motion, t = 10 s
initial velocity of the runner, u = 0 (he started standing still)
final velocity of the runner, v = 36 km/h = 10 m/s
Therefore, to achieve the final speed of the runner, his acceleration is calculated as follows;
v² = u² + 2as
10² = 0 + (2 x 200)a
100 = 400a
a = 100/400
a = 0.25 m/s²
The acceleration of the runner is 0.25 m/s²

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 would doubling the mass of Earth affect the gravity we experience?
What will be the mass of a body at the center of the earth as compared to other places on
the earth?
Answer:
The mass of the object does not change by moving it to another place. ... At the center of the earth the net gravitational force is zero, so the weight will be zero, but its masses will remain same. Hence the mass at the centre of earth will be equl to 50 kg.
Explanation:
It's because the mass of the object doesn't change by moving it to next place.

What are gravity and gravitational force?Gravity is a fundamental force in the universe that causes objects with mass or energy to attract one another. It is a force of attraction between any two objects in the universe that have mass. The force of gravity is directly proportional to the masses of the objects and inversely proportional to the distance between them.
Mathematically,
F=G×m1×m2/r²
The gravitational force is the force of attraction between two objects due to their masses. It is the force that causes objects to be drawn toward one another.
The strength of the gravitational force between two objects is determined by the mass of each object and the distance between them. The larger the mass of an object, the greater its gravitational force, and the closer two objects are, the greater their gravitational force.
Gravitational force is responsible for keeping the planets in orbit around the sun, for the tides on Earth, and for many other natural phenomena. The gravitational force is one of the four fundamental forces of nature, along with the strong nuclear force, the weak nuclear force, and the electromagnetic force.
Here in the question
Jupiter's strong gravitational force can significantly influence the trajectory of a comet, causing it to change direction or even collide with the planet. This is due to Jupiter's massive size, which creates a powerful gravitational pull that can affect objects within its vicinity. In fact, Jupiter is often referred to as the "vacuum cleaner of the solar system" because it has such a strong gravitational pull that it can attract and capture comets and asteroids.
Hence C. Jupiter because of its strong gravitational force, plays a most important role in changing the direction of a comet's path.

An archer shoots an arrow 75 m distant target; the bull's-eye of the target is at the same height as the release height of the arrow. If d = 75 m and v = 37 m/s. At what angle must the arrow be released to hit the bull's-eye if its initial speed is 37 m/s?
Answer:
[tex]16.25^{\circ}[/tex]
Explanation:
R = Horizontal range of projectile = 75 m
v = Velocity of projectile = 37 m/s
g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
Horizontal range is given by
[tex]R=\dfrac{v^2\sin2\theta}{g}\\\Rightarrow \theta=\dfrac{\sin^{-1}\dfrac{Rg}{v^2}}{2}\\\Rightarrow \theta=\dfrac{\sin^{-1}\dfrac{75\times 9.81}{37^2}}{2}\\\Rightarrow \theta=16.25^{\circ}[/tex]
The angle at which the arrow is to be released is [tex]16.25^{\circ}[/tex].

HELP PLEASE:How much work is done to increase the speed of a 2kg body from 36km / h to 72km / h?
Answer:
100 joules (J).
Explanation:
Converting Units - 36 km/h = 10 m/s
72 km/h = 20 m/s ( 1 km/h = 5/18 m/s)
Change in speed = 20 - 10 = 10 m/s
Applying the Work-Energy theorem,
[tex]Work done = \frac{1}{2} 2 (10)^2[/tex]
= 100 J.
