Answer:
a. El tiempo de recorrido es
segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
b. El tiempo de recorrido es 0.118 segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
Explanation:
El sonido es un tipo de onda mecánica, que es un tipo de onda que necesita de un medio material para propagarse. En este caso, entendemos que el sonido se propaga a través del aire atmosférico hasta llegar a su destino y devolverse a rapidez constante. Entonces, podemos estimar el tiempo (
), medido en segundos, a partir de la siguiente fórmula:

Donde:
- Distancia entre la cámara fotográfica y el objeto, medida en metros.
- Rapidez del sonido en el aire atmosférico, medida en metros por segundo.
A continuación, calculamos el tiempo de recorrido:
a. (

)


El tiempo de recorrido es
segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
b. (

)


El tiempo de recorrido es 0.118 segundos para un objeto localizado a un metro de distancia de la cámara fotográfica.
Answer:
variations in great horned owl body size due to food supply can be acted on by natural selection.
Explanation:
Natural selection can help select great horned owl with smaller body size since it's an advantage in a place with smaller available food sources, compared to a bigger body size that will need more food. At first, birds with smaller body survive while those bigger ones die out, and the smaller birds pass on this genes to their offspring.
Answer:
variation in body size due to inherited traits can be acted on by natural selection
Explanation :
Variations in body size in body size due to inherited trait can be acted upon by natural selection by favoring the size that is best suited for the survival of the species. Those with these genes survive and pass it on to their offspring, while those with the unfavorable body size are wiped out.

Answer:
The velocity of the ball when its hit the ground will be 54.22 m/sec
Explanation:
We have given height from which ball is dropped h = 150 m
Acceleration due to gravity 
As the ball is dropped so initial velocity will be zero so u = 0 m/sec
According to third equation of motion we know that 


So the velocity of the ball when its hit the ground will be 54.22 m/sec
