FREQUENCY is the number of complete waves that pass a given point in a certain amount of time.
Good luck :)
Answer:
1. B. Increase
2. A. Decrease
Explanation:
To understand this issue, we need to put some values and using the ohm's law we can corroborate the two situations.
Ohm's law:
Now for the voltage we will use V = 110 [V], for resistance R = 10 [ohms]
Replacing the values we have:
Now let's double the voltage 220 [V]:
Therefore the current will be increased.
Let's do the same for the resistance if originally we have R = 10 [ohms]
Now let's double the resistance 20 [ohms]:
Therefore the current will be decreased.
we know that electromagnetic waves travels faster through the gas than a solid as they do not need medium to travel.
x-ray sis used in taking images of bones in medical field.
since x-ray is an electromagnetic wave , it travels at the speed of 300,000,000 m/s through space
The above mentioned characteristics belongs to x-ray. hence the correct choice is X-ray

Explanation:
Un motor aeronáutico o motor de aviación es aquel que se utiliza para la propulsión de aeronaves mediante la generación de una fuerza de arrastre.
Existen distintos tipos de motores de aviación, aunque se dividen en dos clases básicas: motores recíprocos —o de pistón— y de turbina de gas. Recientemente y gracias al desarrollo de la NASA y otras entidades, se ha comenzado también la producción de motores eléctricos para aeronaves que funcionen con energía solar fotovoltaica.
eso depende de el motor que cada avion tenga
