Answer:
The answer is "Choice B and Choice C".
Explanation:
In this question, the two features, which make electromagnetic waves effective for interaction, which they don't really need a method of travel of data and move information quite fast. The motion among magnetic and electrical forces is generated by electromagnetic radiation. These waves will spread without the need for a source for their movement, and they have high speed and also the electromagnetic waves it has the same frequency as light.
Answer:
The net force and the acceleration on the falling skydiver is upward
Explanation:
An upward net force on a downward falling object would cause that object to slow down. the skydiver this slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
Answer:
a) 35 sequndos b) M1 = 600m M2 = 875m
Explanation:
a)
Antes de que el otro móvil comience a moverse, el primer móvil ha viajado 5 segundos a una velocidad de 15 m / s.
5 segundos x 15 m / s = 75 metros.
Podemos establecer una ecuación con la información que conocemos. Juntos, en total, los dos recorren 1475 metros.
Voy a representar el tiempo como t. Un móvil ya ha recorrido 75 metros y hará otros 15 t. El otro aún no se ha movido y viajará 25t. Esos tres números se sumarán a 1475.
75 + 15t + 25t = 1475.
Resta 75 de ambos lados y suma términos similares de t: 40t = 1400
t = 35 segundos.
b)
Ahora tome la distancia recorrida por cada vehículo por separado y conecte 35 segundos para t.
Primer móvil: 75 + 15t = 75 + 15 (35) = 600m
Segundo móvil: 25t = 25 (35) = 875m
