Misrepresentations of physical stimuli are known as Absolute Threshold


What is stimulus?
A stimulus is a measurable change in the physical or chemical structure of an organism's internal or external environment in physiology. Sensitivity refers to an organism's or organ's ability to perceive external stimuli and respond appropriately (excitability). Sensory receptors can receive information from both inside and outside the body, such as touch receptors in the skin or light receptors in the eye, as well as chemoreceptors and mechanoreceptors. When a sensory receptor detects a stimulus, it can generate a reflex via stimulus transduction. A homeostatic control system's first component is frequently an internal stimulus. External stimuli, such as the fight-or-flight response, are capable of eliciting systemic responses throughout the body.

How does a ramp make it easier to move a heavy object a certain distance?A by decreasing the distance the object movesB by decreasing the amount of work required to move the objectC by changing the direction in which the object movesDby decreasing the amount of force required to move the object

Answers

When lifting an object we are required to produce a force that is greater or equal than the weight of the object in order to be lifted:

When we use a ramp we have the following distribution of forces:

In the ramp, the force decomposes into two components. A component that is parallel to the ramp and a component that is perpendicular to the ramp. Now the force must be greater or equal to the parallel component of the ramp therefore, the amount of force required must be less. Therefore, the ramp makes it easier by decreasing the amount of force required to move the object.

Answer:

By Decreasing the amount of force required to move an object

Explanation:

Objects, especially simple machines, make work easier. They do not decrease the amount of work done, but actually decrease the amount of force applied. The less force applied, the easier it is to do work. Simple machines and other objects that help make work easier decrease the amount of force required to move an object.

So the answer is-

A ramp makes work easier by decreasing the amount of force required to move an object

Answers

Answer:

Explanation:

The dimensions of the scale model have the same ratio of the original dimensions. The ratio of the original dimenstions is

240/60 = 4

Then, the ratio for each option is

A. 360/90 = 4

B. 3/1 = 3

C. 80/20 = 4

D. 480/120 = 4

Therefore, B is not a correct option.

Additionally, we don't use A because the units for length and width are different

And we don't use D because the measures are too long for a model.

Therefore, the answer is

A train car with a mass of 14 kg and speed of 30 m/s is traveling to the right. Another train car with a mass of 26kg is moving with an unknown velocity. After the collision, the 14 kg train car is stuck to the 26 kg train car with a combined velocity of 12 m/s

Answers

From the Law of Conservation of Linear Momentum, when two particles get stuck together after a collision, it follows that:

[tex]m_1v_1+m_2v_2=(m_1+m_2)v_f[/tex]

In this case, the initial velocity of the second particle is unknown. Isolate it from the equation:

[tex]v_2=\frac{(m_1+m_2)v_f-m_1v_1}{m_2}[/tex]

Replace the given data to find the value of v₂:

[tex]\begin{gathered} m_1=14kg \\ v_1=30\frac{m}{s} \\ \\ m_2=26kg \\ v_2=\text{ unknown} \\ \\ v_f=12\frac{m}{s} \\ \\ \Rightarrow v_2=\frac{(14kg+26kg)(12\frac{m}{s})-(14kg)(30\frac{m}{s})}{26kg}=2.3077...\frac{m}{s} \\ \\ \therefore v_2\approx2.3\frac{m}{s} \end{gathered}[/tex]

Therefore, the initial velocity of the 26-kg car is approximately 2.3m/s.

Answers

The mass of the second skater is equal to 27 Kg, which acquires a speed of 3.81 m/s.

What is law of conservation of linear momentum?

According to the law of conservation of momentum, the sum of the momentum of the two objects before and after the collision must be equal.

m₁ u₁ + m₂u₂ = m₁ v₁ + m₂ v₂

where m₁ and m₂ is the mass of the collided bodies, u₁ and u₂ are the initial speed while v₁ & v₂ is their final speed.

The linear momentum can be described as the product of the mass times the velocity of the object. Conservation of momentum is a characteristic held by an object where the total amount of momentum remains the same.

Given the initial speed of the skaters is equal to zero so  u₁ = u₂ =0

The mass of the one skater, m₁ = 49 Kg

The first skater acquires the speed, v₁ = 2.10 m/s

The speed acquired by the second skater, v₂ = -3.81 m/s

From the law of conservation of momentum, we can find the mass of another skater:

m₁ u₁ + m₂ u₂ = m₁v₁ + m₂ v₂

49 × 0 + m₂ ×0 = 49 × (2.10) + m₂ × (- 3.81)

m₂ = -49 × (2.10)/ (- 3.81)

m₂ = 27 Kg

Two audio speakers are placed on a vertical rail. Speaker A is placed at head-level while Speaker B is place at some variable height, Δy, above Speaker A. Both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.880 meters. Calculate the lowest height that Speaker B can be placed above Speaker A to produce a minimum of sound heard by person standing Δx=6.38 meters directly in front of Speaker A.

Answers

The lowest height at which speaker B can be placed above speaker A to produce the lowest sound to the person standing in front of A by superposition and wave interference is ∆y ≈ 2.41 m.

What is the superposition principle?

The superposition principle states that the magnitude of the resulting wave when two waves overlap is the sum of the disturbance of the individual waves.

The given parameters are;

Height of speaker B above speaker A = ∆y

Wavelength of the wave = 0.880 meters

Distance between the person standing directly in front of speaker A and speaker A, ∆x = 6.38 meters

Required;

The minimum height of speaker B above speaker A that produces the minimum sound to the person in front of speaker A

Solution;

The minimum sound is given when there is destructive interference of the waves produced by the speakers

When there is destructive interference, the peak of the wave from speaker A coincides with the through of the wave from speaker B which gives;

Distance between a peak and the through of a wave = 0.5 × The wavelength

Therefore, for minimum sound, we have;

Distance from the person to speaker B = 6.38 m + 0.5 × (The wavelength)

Which gives;

Distance from the person to speaker B = 6.38 m + 0.5 × 0.88 m = 6.82 m

Pythagorean theorem is used to find the height of speaker B above speaker A as; ∆y = √(6.82² - 6.38²) ≈ 2.41

Answers

The velocity and acceleration of the marble will be greater when it travels 1.5 m compared to 0.5 m.

What is velocity?

The velocity of an object is the rate of change of displacement with time.

The velocity of the marble after it has travelled the given distance is calculated as follows;

v² = u² + 2as

where;

v is the final velocity of the marbleu is the initial velocity of the marbles is the distance travelled by the marblea is the acceleration of the marble

Assuming the marble started from rest, without initial velocity, our final equation becomes.

v² = 0² + 2as

v² = 2as

v = √2as

Acceleration is defined as the rate of change of velocity over time. Acceleration is a vector quantity because it has both magnitude and direction. It is also the second derivative of position with respect to time or the first derivative of velocity with respect to time. Acceleration is the name we give to the process of changing velocity. Because speed is speed and direction.

There are only two ways to accelerate. Either change speed change direction or change both. Acceleration is the rate of change of velocity. At any point in the orbit, the magnitude of the acceleration is given by the rate of change of magnitude and direction of velocity at that point. Velocity is the primary measure of object position and velocity. It can be defined as the distance traveled by an object in a unit of time.
