I believe It's either a supernova or a planetary nebula.
Answer: Viendo que los aviones viajan muy raramente exactamente en la misma dirección que el para compensar continuamente tanto la dirección como la velocidad del vientoLos vientos en contra significa exactamente lo contrario; se necesita más combustible y el vuelo llevará más tiempo condiciones secas y húmedas, pero el piloto tiene la decisión final sobre si.
Answer:
a. Speed = 1.6 m/s
b. Amplitude = 0.3 m
c. Speed = 1.6 m/s
Amplitude = 0.15 m
Explanation:
a.
The frequency of the wave must be equal to the reciprocal of the time taken by the boat to move from the highest point to the highest point again. This time will be twice the value of the time taken to travel from the highest point to the lowest point:
frequency =
= 0.25 Hz
The wavelength of the wave is the distance between consecutive crests of the wave. Therefore,
Wavelength = 6.4 m
Now, the speed of the wave is given as:
Speed = (Frequency)(Wavelength)
Speed = (0.25 Hz)(6.4 m)
<u>Speed = 1.6 m/s</u>
b.
Amplitude is the distance between the mean position of the wave and the extreme position. Hence, it will be half the distance between the highest and lowest point:
Amplitude = (0.5)(0.6 m)
<u>Amplitude = 0.3 m</u>
c.
frequency =
= 0.25 Hz
Speed = (Frequency)(Wavelength)
Speed = (0.25 Hz)(6.4 m)
<u>Speed = 1.6 m/s</u>
Amplitude = (0.5)(0.3 m)
<u>Amplitude = 0.15 m</u>
Answer:
30 kilometers per hour.
Explanation:
we know this by dividing 60 by 2
