What causes the apparent colors of the objects we see?
Answers
Answer: The human eye and brain transform light into color. Allowing us to see them.
Explanation: Light receptors within the eye turn light into color. The color that is reflected off of an object, is what we see. Hope this helps.
The apparent colors of the objects we see causes due to reflection of the light which they absorb and emit.
What is reflection?Reflection is the change in direction of a wavefront which occurs at an interface present between the two different media so that the wavefront of the wave returns into the medium from which it has been originated. Common examples of reflection include the reflection of light, sound wave and water waves.
The color of an object is the wavelengths of light waves that it reflects. The reflection is determined by the arrangement of electrons in the atoms of that substance which will absorb and re-emit photons of particular energy levels according to the quantum laws.

a 2kg book falls off the top of a 2.3m bookshelf. how much work is required to lift the book back to it's original position? gravity acceleration is 9.58 m/s ²
Answers
Answer:
44.068 J
Explanation:
From the question,
Work(W) = mgh............... Equation 1
Where m = mass of the book, g = acceleraton due to gravity, h = height.
Given: m = 2 kg, h = 2.3 m, g = 9.58 m/s²
Substitute these values into equation 1
W = 2×2.3×9.58
W = 44.068 J
Hence the work required to lift the book is 44.068 J

explain why the magnetic field in solenoid is Greater if the solenoid has an iron core?
Answers
Answer:
he magnetic field is greater because the magnetization of the material is added
Explanation:
The magnetic field in a solenoid is given by the relation
B₀o = μ₀ n I
where n is the density of turns and I the current
When we put a magnetic material inside solenoid
the magnetic field is
B = B₀ + μ₀ M
where M is called the magnetization of the material and corresponds to the alignment of the magnetic moments of the atoms with the field, therefore the total field is much greater, it should be noted that the part of Bo increases with the current, but the magnetization has a maximum value.
Consequently the magnetic field is greater because the magnetization of the material is added

I used this formula to get the formula for Vy:
v^2=vi^2+2(a)(x)
And got
Vy=square root (19.6 h)
Then I used that and put it in this formula:
tan(65) =Vy/Vx
tan(65) = square root (19.6 h)/15.0
Then I rearranged it to:
h=[(15.0)(tan65)]/19.6
h=52.79 m
when is the object at rest? in constant speed? accelerating?
Answers
Answer:
Answered in explanaion.
Explanation:
REST: When an object does not change its position with respect to its frame of reference or surrounding, then the object is said to be in the state of rest.
CONSTANT SPEED: When the object covers equal distance in equal intervals of time, the object is said to be moving with constant speed.
ACCELERATING: An object is said to be accelerating when the speed of the object increases with respect to time.

A non -viscous incompressible fluid is pumped steadily into the narrow end of a long tapered pipe and emerges from the wide end . The pressure at the input is greater than at the output . A possible explanation is :
Answers
Answer:
v₂ =[tex]( \frac{r_1}{r_2})^2 \ v_1[/tex]
Explanation:
This phenomenon is explained by the continuity equation in fluids
v₁A₁ = v₂A₂
where the subscript 1 is for the input narrow part and the subscript 2 for the wide part
v₂ = [tex]\frac{A_1}{A_2} v_1[/tex]
consider the cross section at each point
A₁ = π r₁²
A₂ = π r₂²
we substitute
v₂ =[tex]( \frac{r_1}{r_2})^2 \ v_1[/tex]
therefore the exit velocity is less than the entrance velocity of the fluid.
We can also analyze the situation using Bernoulli's equation
P₁ + ρ g v₁² + ρ g y₁ = P₂ + ρ g v₂² + ρ g y²
if we assume a horizontal system y₁ = y₂
P₁-P₂ = ρ g (v₂² - v₁²)
Which items would have this energy transformation: chemical energy -> mechanical energy?
Answers
Answer:
La transformación energética, transformación de la energía, conversión energética o conversión de la energía es el proceso de cambiar la energía de un tipo de energía a otro. En física, la energía es una cantidad que proporciona la capacidad de realizar un trabajo (por ejemplo, levantar un objeto) o proporciona calor. Además de ser convertible, de acuerdo con la ley de conservación de la energía, la energía es transferible a una ubicación u objeto diferente, pero no se puede crear ni destruir.
La energía en muchas de sus formas se puede utilizar en procesos naturales o para proporcionar algún servicio a la sociedad, como calefacción, refrigeración, iluminación o realizar trabajos mecánicos para operar máquinas. Por ejemplo, para calentar una casa, el horno quema combustible, cuya energía potencial química se convierte en energía térmica, que luego se transfiere al aire de la casa para elevar su temperatura.
