The bones of the middle ear cause which structure in the inner ear to vibrate and change the sound into signals?
a) eardrum
b) cochlea
c) hammer
d) auricle

Answers

Answer 1

Answer:

B

Explanation:

The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus.

Answer 2

Answer:

the answer is the cochlea

Explanation:

the eardrum receives the sounds and the cochlea "decifers them" so you know what words people are saying or what sound is playing.

What is inertia and how can you increase an object's inertia?

Answers

Answer:

Explanation:

Inertia is the property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity.

The more mass, the more inertia. If you increase the mass of the object then you increase the inertia.

Calculate the total momentum of the three-sphere system if the three spheres are swung at −1.0 msto the left.

Answers

Answer:

, pfx = pix + Jx.

Explanation:

The momentum principle tells us that impulse transfers momentum to an object.

If an object has 2 kgm/s of momentum, a 1 kgm/s impulse delivered to the object

increases its momentum to 3 kgm/s. That is, pfx = pix + Jx.

Just as we did with energy, we can represent this “momentum accounting” with a

momentum bar chart. For example, the bar chart of FIGURE 11.6 represents the ball

colliding with a wall in Figure 11.4. Momentum bar charts are a tool for visualizing

Consider two soap bubbles having radii r1 and r2 (r1 < r2) connected via a valve. What happens if we open the valve?

Answers

Answer:

Explanation:

The radius of the smaller bubble, r1 will decrease and that of the bigger bubble, r2 will increase.

The pressure that is present in the smaller bubble usually is greater than the pressure that exists inside that of the bigger bubble. This then makes air to flow from r1 to r2 thereby making the radius of the smaller bubble r1, to decrease while keeping that of the bigger bubble r2 higher.

What is the kinetic energy of a 78kg object moving at a velocity of 2.5m/s

Answers

Answer:

[tex]\boxed {\boxed {\sf 243.75 \ J }}[/tex]

Explanation:

Kinetic energy is energy an object has due to motion. The formula is:

[tex]KE=\frac {1}{2}mv^2[/tex]

The mass of the object is 78 kilograms and the velocity is 2.5 meters per second.

[tex]m= 78 \ kg \\v= 2.5 \ m/s[/tex]

Substitute the values into the formula.

[tex]KE= \frac {1}{2} (78 \ kg)*(2.5 \ m/s)^2[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Solve the exponent first.

(2.5 m/s)²= 2.5 m/s * 2.5 m/s = 6.25 m²/s²

[tex]KE= \frac {1}{2}(78 \ kg)*6.25 \ m^2/s^2[/tex]

Multiply all three numbers together.

[tex]KE=39 \ kg * 6.25 \ m^2/s^2\\[/tex]

[tex]KE=243.75 \ kg*m^2/s^2[/tex]

1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 243.75 kg *m²/s² is equal to 243.75 Joules.

[tex]KE=243.75 \ J[/tex]

The object has 243.75 Joules of kinetic energy.

If a chemical reaction has a AH value of -125 kJ, it would be considered what?

Answers

Answer:  

Exothermic Reaction  

Explanation:  

ENDOTHERMIC REACTION: A chemical reaction is considered endothermic if the energy is absorbed during the reaction. In other words, if the energy is required by the reactants to proceed with the reaction, then the reaction is endothermic.

The value of enthalpy change ΔH is positive in such reactions showing intake of energy.

EXOTHERMIC REACTION: A chemical reaction is considered exothermic if the energy is released during the reaction. In other words, if the energy is produced as a product of the reaction, then the reaction is exothermic.

The value of enthalpy change ΔH is negative in such reactions showing the release of energy.

Since, the value of ΔH = -125 KJ, is negative for the given reaction.

Therefore, it would be considered as Exothermic Reaction.

Well for starters, that means that the air in the sky is very cold, and has a lower temperature. Since it is super dark, it is colder than the polar bear.

The polar bear is cold. Not as cold as the sky, and not as warm as the mouth and eyes, but it is still very cold. This is probably because it lives in a snowy and cold climate.

The polar bears eyes and mouth are warm. This is because, the spots where the eyes, mouth, and nose are is a very light shade. This concludes that those spots on the polar bear are warm.

If a 12 kg object's velocity changes from 5 m/s to 10 m/s in 5 s, what amount of force was applied to increase the speed of the object?

Answers

Answer:

12 N

Explanation:

Given that a 12 kg object's velocity changes from 5 m/s to 10 m/s in 5 s, what amount of force was applied to increase the speed of the object?

Solution

M = 12 kg

T = 5 s

The formula to use will be

F = ma

Where

Acceleration a = change in velocity/ time

Acceleration a = ( 10 - 5 ) / 5

Acceleration a = 5 / 5

Acceleration a = 1 m/s^2

Substitutes a into the formula above

F = ma

F = 12 × 1

F = 12 N

Therefore, the amount of force applied to increase the speed of the object is 12 N.
