The third table shown in the diagram below can be modelled with the equation, y = x + 2, therefore, it represents a linear equation.
What is a Linear Function?A linear function is a function whose graph represents a straight line when the points are plotted, and also can be modelled by the equation, y = mx + b.
b is the value of y when x = 0 (y-intercept)
m is the slope or unit rate.
Thus, the third table shown in the diagram below can be modelled with the equation, y = x + 2, therefore, it represents a linear equation (see attachment). The last table has a constant slope of -3, hence it represents a linear function.
Table of functions
From the given table, we need to determine which of the table is a linear table. To determine that, we must check which of the table has a constant rate of change
Looking at the last table;
Slope = -4-(-2)/2-1
Slope = -4+1/1
Slope = -3
Since the last table has a constant slope of -3, hence it represents a linear function.

What is latent heat ?The quantity of heat (in joules or calories) per mole or unit mass of the substance undergoing a change in state is the typical way to represent latent heat.
The latent heat involved in melting solids or freezing liquids is referred to as the "heat of fusion," while the latent heat involved in vaporizing solids or liquids or condensing vapor is referred to as the "heat of vaporization."
When water boils at 100°C and turns into steam, water vaporizes into steam by absorbing heat of vaporization. This heat energy remains in the steam as kinetic energy and makes their movement fast.
So, The molecules will have more space between them and will be moving at higher speeds as steam compare to water.

Explanation:
A 200kg car is coasting to the right and slowing down due to a friction force of 200N.
By Newton's second law, the net force on the car is
∑ F = m a
where m is the mass of the car and a is magnitude of the acceleration.
The car is slowing down, so the net force opposes the direction in which the car is moving. Vertically, the car is in equilibrium, the net force is entirely due to friction. Taking the direction opposite the car's motion to be negative, we have
- 200 N = (200 kg) (-a)
a = (200 kg) / (200 N)
a = 1 m/s²
If you're also supposed to find the coefficient of kinetic friction, use the fact that the car the vertical forces cancel out, namely
n + (-w) = 0
where n is the magnitude of the normal force and w is the car's weight. The friction force f is proportional to the normal force n by a factor of µ, the coefficient of kinetic friction, such that f = µ n. Then
f / µ = w
(200 N) / µ = (200 kg) (9.80 m/s²)
µ = (200 N) / ((200 kg) (9.80 m/s²))
µ ≈ 0.102

Which shows the correct angle of reflection given the incident ray shown?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
The angle of reflection given the incident ray from the given diagrams is option C.
What is the refraction of light?When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.
When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.
The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.
Thus, the ideal solution is option C.
