when is the object at rest? in constant speed? accelerating?
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.

What causes the apparent colors of the objects we see?
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.

Which items would have this energy transformation: chemical energy -> mechanical energy?
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.

Newton's 2nd Law describes the relationships between force, mass and acceleration. What is the exact
relationship between force and acceleration if mass were to remain constant?
Newton’s second law of motion seems simple enough: Push on an object of a certain mass, and it accelerates based on the amount of force and mass. A small force with a large mass results in a slow acceleration, and a large force with a small mass gives a fast acceleration. What happens when there’s no force? A force of zero on any mass gives zero acceleration. If the object is standing still, it remains still; if it’s moving, it continues to move at the same speed and direction. Keep in mind that several forces can be involved at the same time. For example, you tie a rope around a boulder and pull with all your might. There are force and mass, but the boulder doesn’t budge, so acceleration is zero. The force of friction between the boulder and the ground cancels out the force of your pull. You need a much bigger force, such as from a tractor, to move the boulder.
Answer:
Force ∝ Acceleration
Explanation:
Force is directly proportional to acceleration. This is because as you increase force, the acceleration increases.

If a riding lawnmower engine exerts 19 hp in one minute to move the mower, how much work is done? (Hint convert: 1 watt equals 0.00135962 hp)
Answer:
Work done = 838470 Joules.
Explanation:
Given the following data;
Power = 19 hp
Time = 1 minute to seconds = 60 seconds.
Next, we would convert the unit of power in "hp" to "Watt."
1 Watt = 0.00135962 horsepower
x Watt = 19 horsepower
Cross-multiplying, we have;
19 = 0.00135962x
x = 19/0.00135962
x = 13974.5 Watts.
Now, to find the work done in moving the mower;
Work done = power * time
Substituting into the formula, we have;
Work done = 13974.5 * 60
Work done = 838470 Joules.

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
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

Mac and Suzanne cut holes in the bottom of two cups and connect them with a string. When Mac whispers into one cup,
Suzanne can hear him through the other. What is the best reason to explain why this happens?
A
Sound waves produce an echo.
B
Sound waves can travel great distances.
Sound waves travel better through solids than gases.
D
Sound waves from whispering have a higher frequency
Answer:
Answer is D
Explanation:
The sound travels along the string as a longitudinal wave and ultimately vibrates the bottom of the receiving cup. The cup transmits the sound into the air around the listener's ear, allowing her to hear the speaker.
Mac and Suzanne cut holes in the bottom of two cups and connect them with a string. When Mac whispers into one cup, Suzanne can hear him through the other. This is because sound waves produce an echo. Thus, the correct option is A.
What is an echo?In audio signal processing and acoustics, an echo can be defined as a reflection of sound waves which arrives at the listener with a delay in time after the direct sound waves. The delay in this is directly proportional to the distance of the reflecting surface from the source and that of the listener.
An echo is the repetition of sound which results due to reflection from a surface. We cannot hear an echo until and unless there is a reflecting surface present beyond a specified distance from the source of the sound wave. The minimum distance which is required to hear an echo is 17.2 meters. The sensation of sound persists for the time period of 0.1 second.
Therefore, the correct option is A.

Explanation:
Acceleration = [tex]\frac{Force}{mass}[/tex]
Force = 11N
Mass = 5.9 kg
∴ Acceleration = [tex]\frac{11}{5.9}[/tex]

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 :
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)
