Audition begins when sound waves strike the ________,causing it to vibrate. A) eardrum B) anvil C) stirrup D) cochlea

Answers

Answer 1
Answer:

Answer: A) eardrum

Explanation: Audition refers to the sense of hearing. It is the process by which sound waves are perceived and interpreted by our brain. When sound waves enter the ear, they cause the eardrum to vibrate. These vibrations then travel further into the inner ear, leading to a chain of events that ultimately allows us to interpret and understand the sounds that we hear. Therefore, A is correct.

That's it!

How does inertia affect a person who is not wearing a seatbelt during a collision?

Answers

well an object in motion stays in motion. the body would continue to go at the speed the car was going before it was hit, and then the boy would go threw the windshield (if they are in the front seat). Which means inertia wouldn't have any affect on the person until they hit the windshield and then the pavement. Hope this makes sense to you!
En caso de una colisión de bajo nivel de gravedad podría golpearse con el tablero del carro o en la parte del sillón (si esta sentado en la parte trasera). Pero si es muy grave la colisión podría salirse del carro por el cristal.

Emilio's teacher told his class that a controlled experiment's results are valid only if one factor in the experiment is changed and all the other factors remain constant. Why is this statement true?Changing several different factors in an experiment takes too much time.

Changing several different factors in an experiment takes too many controls.

When only one factor is changed, you don't need to use a control.

When only one factor is changed, you can be more certain that it caused the results.

Answers

Actually, two of the statements can be argued to be true:
1)Changing several different factors in an experiment takes too many controls.

This means that for every factor that is changed you need a control which has all the other factors stable - but with many factors, this might be undoable.

2) - and this is the best answer:
When only one factor is changed, you can be more certain that it caused the results.

If this factor is the only thing that changes, you can safely assume that it caused the results!

A.  When only one factor is changed, you can be more certain that it caused the results.

There are several ways to make sure the results of an investigation are valid. First, you and others can try to repeat the experiment. In addition, if it is a controlled experiment, you can make sure you have a control, only one independent variable, at least one dependent variable, and constants.

It is especially important to use only one independent variable because when only one factor is changed, you can be more certain that it caused the results. If you change multiple factors, you won't know which one was responsible for the change.

Which factors are used the calculate the kinetic energy of an object? Check all that apply. gravity velocity volume mass height

Answers

The factors that are included in the calculation of the kinetic energy of an object would be the velocity and its mass. The kinetic energy's formula is half of the product of the mass and the velocity that is squared. The volume, height, and gravity are not included.
Kinetic energy = (1/2) (the object's mass) (its speed or velocity)²  .

No other quantities are involved.

What is the equation for calculating electric power?

Answers

Power consumed by an electric device, or dissipated as heat, is

Power = (voltage between the ends of the device) x (current through it)  
The equation for calculating electric power is given by the folloowing equation : -

P = VI

Where P stands for power, V for potential difference and I for current.
