The direction the horse travels has nothing to do with its speed but...
The horse would be traveling 6.25 km/hr
You simply take the overall travel (25km) and divide it by the total time (4hr)
You get 6.25km as your answer, meaning that every hour the horse traveled 6.25km every hour.
4 hours later the horse has reached 25km
Answer:
Explanation:
<h3>a and b</h3>
We can use the following formula, from kinematics:

where
is the final speed,
is the initial speed, a is the acceleration and d the distance traveled.
Knowing that the final speed is zero, and the initial speed is

we obtain



Now, knowing that

then


<h3>c</h3>
We can use the following formula

so



<h3>d</h3>



i don't know what symbol ya'll use for wavelength so i just put the word instead.We use the greek symbol lambda.So just plug in everything you know.
wavelength=4.257×10^-7x10^-2 and
v=speed of light = 3×10^8
So you should get f= 7.04 ×10^15Hz
Answer: A. force with which air rushes across the vocal folds
Explanation:
The human voice is produced in the larynx, whose essential part is the glottis. This is how the air coming from the lungs is forced during expiration through the glottis, making its two pairs of vocal folds to vibrate.
It should be noted that this process can be consciously controlled by the person who speaks (or sings), since the variation in the intensity of the sound of the voice depends on the strength of the breath.
