1 answer:
Answer:
La profesora Fernanda da 452.381 mililitros de agua fresca a cada estudiante.
Explanation:
Sabemos que un litro equivale a 1000 mililitros, inicialmente obtenemos la capacidad de cada hielera al dividir la capacidad completa por el total de hieleras:
Si sabemos que cada hielera es utilizada por 7 estudiantes, entonces obtenemos la capacidad asignada a cada uno al dividir la capacidad de la hielera por el número de estudiantes:
La profesora Fernanda da 452.381 mililitros de agua fresca a cada estudiante.

Answer:
108 km
Explanation:
The conversion factor between meters and feet is
1 m = 3.28 ft
So the second altitude, written in feet, can be rewritten in meters as
or in kilometers,
the first altitude in kilometers is
so the difference between the two altitudes is
If one of two interacting charges is doubled, the force between the charges will double.
Explanation:
The force between two charges is given by Coulomb's law
K=constant= 9 x 10⁹ N m²/C²
q1= charge on first particle
q2= charge on second particle
r= distance between the two charges
Now if the first charge is doubled,
we get
F'= 2 F
Thus the force gets doubled.
To solve the problem it is necessary to take into account the concepts related to beat frequency, i.e., The number of those wobbles per second.
The equation that describes the beat frequency is
For our given case we have that the frequency of the instrument is 440Hz and the Beat frequency is 5Hz therefore,
A) The frequency of the violin would be given by
B) <em>The violinist must loosen the string.</em> As the tightening increases the frequency, thereby increasing the number of beats from 5 to 6, i. e, on thightening the string, the frequency further increases as high frequency will be produced by short trings.
