What is the purpose of sensory adaptation

Answers

Answer 1

Answer: Sensory adaptation is when the sensory receptors change and adapt to different stimuli. For example in a darkened room your pupils enlarge allowing more of the available light in. This is why you can see a little better in the dark after you get used to it.

Answer 2

Answer: Sensory adaptation is a phenomenon in which sensory neurons change their level of sensitivity to a constant stimulus over time. This adaptation allows people to adapt to their environments while balancing the need to receive new sensory input. Neurons involved with smell, hearing, taste, touch, and sight can all exhibit this phenomenon.

A box weighing 18 N requires a force of 6.0 N to drag it at a constant rate. What is the coefficient of sliding friction?

Answers

Use f = uN to find the coefficient of friction. We know friction (6.0 N) and the normal forces (18 N), so plug them in to the equation which gives us 6 = u18. Solving for u: u = 0.33

The Correct Answer Is 0.33.

Heat transfers through Earth's systems in different ways. In which atmospheric action can we see evidence of conduction? Cold air pushes warm air upward, creating a current. Cold air pushes warm air upward, creating a current. The surface of the Earth heats the air that contacts it. The surface of the Earth heats the air that contacts it. Radiation from the Sun heats the surface of the Earth. Radiation from the Sun heats the surface of the Earth. Air increases in density and sinks back towards the Earth.

Answers

Answer:

B. The surface of the Earth heats the air that contacts it.

Explanation:

Conduction is a mode of heat transfer in which energy is transferred from a hot molecule to the neighboring molecules due to contact. Thus, heat energy is transferred from one molecule to another in the process.

Therefore, the air that comes in contact with the surface of the earth heats up by conduction. Since the surface of the earth is heated up due to the radiation from the Sun.

-g A small block is attached to an ideal spring and is moving in SHM on a horizontal frictionless surface. The amplitude of the motion is 0.165 m. The maximum speed of the block is 3.90 m/s. What is the maximum magnitude of the acceleration of the block?

Answers

Answer:

a= 92. 13 m/s²

Explanation:

Given that

Amplitude ,A= 0.165 m

The maximum speed ,V(max) = 3.9 m/s

We know that maximum velocity in the SHM given as

V(max) = ω A

ω=Angular speed

A=Amplitude

$\omega =(3.9)/(0.165)\ rad/s$

ω=23.63 rad/s

The maximum acceleration given as

a = ω² A

a= (23.63)² x 0.165 m/s²

a= 92. 13 m/s²

Therefore the maximum magnitude of the acceleration will be 92. 13 m/s².

a baseball bat balances 74.8 cm from one end. if an 0.542-kg glove is attached to that end, the balance point moves 25.9 cm toward the glove. calculate the mass of the bat

Answers

The mass of the bat is approximately 1.56 kg. We can use the principle of moments to solve this problem. According to the principle of moments, the sum of the moments of all the forces acting on an object is equal to zero, assuming that the object is in equilibrium.

Let's assume that the bat has a mass of m kg and its center of mass is located at a distance of x cm from the end of the bat where the glove is attached. We can then write the following equation for the moments:

mx = (m+0.542)(x+74.8-25.9)

Here, the left-hand side represents the moment of the bat about the point where the glove is attached, and the right-hand side represents the moment of the bat and the glove about the same point. We have added the distance between the center of mass of the bat and the point where the glove is attached (74.8 cm) to the distance between the glove and the point where the glove is attached (-25.9 cm) to get the total distance between the center of mass of the combined system and the point where the glove is attached.

Simplifying the equation, we get:

m*x = (m+0.542)*48.9

Expanding the brackets, we get:

mx = 48.9m + 26.56

Rearranging and solving for m, we get:

m = 0.542*74.8/(-25.9) = 1.56 kg

Therefore, the mass of the bat is approximately 1.56 kg.
